A Botanist Documents a Rare Nightshade in the California Desert - Observation of the Week, 2/23/21

Our Observation of the Week is this Nevada Oryctes (Oryctes nevadensis), seen in the United States by @swinitsky!

As a child growing up in Los Angeles, Sophie Witnisky says she didn’t encounter much real wilderness but learning to garden “helped me develop an eye for biodiversity and I wanted to learn as much as I could, specifically about plants.” After some time working in sustainable agriculture, she heard about professional botanists

and that shifted everything. My first solo and careful exploration of wilderness came when I took a seasonal job (living right next to where we found the Oryctes nevadensis!) with the Inyo National Forest. From there, my life has been shaped by searching for, identifying and asking questions to plants.

Currently a student at Montana State University, she studies Marina, “a mostly Mexican, glandular, arid-dwelling genus of legume.” Another area of interest is the flora of the Eastern Sierra, “specifically areas impacted by the LA aqueduct.”

[Growing up in Los Angeles,] I felt a personal connection and responsibility towards the land and water grab between eastern California and Los Angeles. It felt right to pursue research that follows up on the long term botanical impacts of the aqueduct. This week I published a conservation plan [PDF] for Calochortus excavatus, a rare plant that runs the entire length of the aqueduct and my M.S. research was on the flora of alkali meadows and marshes, the habitat most impacted by the aqueduct. I also follow this entire area on iNaturalist, which allows me to plan my fieldwork efficiently, since phenology fluctuates a lot, and to keep an eye out for plants I don't know.

In May of 2019, Sophie was in the area with three other botanists: Isaac Marck (@california_naturalist), Maria Jesus (@mariaj),j and Nico Medina (@botanico_las), “which makes looking for plants a lot more fun and a lot slower paced.”

The Oryctes nevadensis population we documented is along the Owens River, which is severely impacted by the aqueduct. This area is heavily botanized - it's California! - so finding something so rare, close to highway 395, reminds us how much there is to learn. The other known populations are farther south and are quite likely extirpated, they were last documented in the early 1980s. We had heard about this population found on sand dunes near the White Mountain Research Station, in Bishop, where we were staying, but the plants rarely come up since they need a specific precipitation regime.

Expectations were low since we heard this population was last seen in the fifties, but it was so snowy (even though it was summer, note the strange rain pattern) that our more glamorous botanizing locations were inaccessible...This population is also highly at risk due to the off roading that happens directly on the plants. They don't look like rare wildflowers, they look like sticky weeds, or perhaps even escaped tomatoes!

The nondescript appearance of Oryctes nevadensis is also a plus for Jim Morefield (@jdmore), a botanist with the Nevada Division of Natural Heritage, who was kind enough to tell me a bit more about the species. “As an inconspicuous desert annual,” he says, “Oryctes nevadensis is automatically on my list of favorite plants.” However, he’s never actually come across one.

Seeing Oryctes nevadensis in the flesh has been on my bucket list for the entire 30 years I have worked as a rare plant botanist in Nevada, but the timing just never worked out. So imagine my delight (and sense of irony) at seeing the first live photos of the species in Sophie’s well-documented observation from California! Its main geographic range is in the sandy valleys of the Lahontan Basin in west-central Nevada, and it only barely spills over into California in similar habitats at the southwestern corner of its range. It is found nowhere else in the world.

The species was first discovered and named in 1871, from specimens found near the lower Truckee River. This rare desert annual is of conservation concern in both Nevada and California, and it is so rarely seen because of its inconspicuous appearance and tendency to germinate only in exceptionally wet spring seasons, like 2019 was.

Due to its rarity, Jim tells me little else is known about the species, although it does belong to the nightshade family (Solanaceae), hence its similarity to tomatoes.

In addition to posting photos of rare plants, Sophie (above) uses iNat in her research on Marina. “Many of these beans have only been seen a couple times or are just known from type collections, so iNaturalist is incredibly helpful,” she explains.

Like Oryctes, they can look weedy or uninteresting (obviously I do not agree) and can be easily overlooked, but uploading them to iNat is easy and advances our understanding of their distribution. I am working on the systematics of the group as a PhD project and hoping to better understand their rarity, evolution, biogeography and conservation. I follow them and all their close relatives on iNaturalist and it helps me track phenology, plan my fieldwork and network with local botanists.

A Euphorbia Observation in Brazil Provides Tantalizing Natural History Clues - Observation of the Week, 2/8/21

Our Observation of the Week is this likely Euphorbia duckei plant, seen in Brazil by @nelson_wisnik.

While he always enjoyed being out in nature, Nelson Wisnik says “I only started paying more attention to fauna and flora when I became a professor of physics in forestry and agricultural engineering courses, showing how physical conditions shape beings, how the energy flow governs the interactions between them, from the point of view of physics.”

Now retired, he spends much of his time trying to observe, record, and share biodiversity. After living on a boat in the central Amazon region from 2002-2008, he spends several months every year exploring the area. He’s also volunteered as an environmental educator in Brazil as well. And of course, that’s where he came across these peculiar plants.

“In the region of the mouth of the Tapajós River, the level of the rivers presents an annual variation of approximately 6.5 m (21 feet) between flood and ebb,” explains Nelson.

The beaches appear on the banks of the rivers and vast areas of lowland are drained, allowing the growth of many species of plants, which, in turn, attract a wide variety of fauna, including migratory species. In this scenario, on two occasions I observed, among other species of the same genus, the Euphorbia duckei. Not being a botanist or biologist, I didn't immediately realize the value of these observations, but [only] later on, during the discussion about their identification.

That discussion included @trh_blue and @nathantaylor, who is iNat’s top Euphorbia identifier. While Nathan says “the only way to be absolutely sure is to see a cyathium on the plant,

E. duckei is the only species known from Brazil that gets that woody and shrubby and has straight branches like those in the observation. What's more, the type locality is along the Tapajós River (the observation was found where the Tapajós River meets the Amazon River.) While geography alone doesn't rule out other species growing in the area and morphology isn't enough to rule out the possibility of an undescribed species or some other new occurrence, together they give pretty good evidence for the identity of the species.

Nathan is quite sure that, aside from the type specimen, these are the only records of E. duckei online and tells me they provide a lot of interesting life history information that wasn’t previously available. “To give a sense of how little is given about the species,” says Nathan,

I'll quote the describer of the plant Léon Croizat in 1943: "The characters of this plant are outstanding, and that it represents a new species seems to be obvious. The material, however, is hardly satisfactory for a generalized description, because it shows a stage in which the new growth is barely beginning, but the old branchlets have already lost their leaves." The observations [Nelson actually observed this species in 2018 as well - Tony] provided show most of what the type specimen lacks. It also gives a more accurate scale of the plant that a specimen simply can't provide. But more interesting to me than the above, it shows the habitat of the species. The observations show that the plant can clearly survive with their roots under water, a condition that would kill any perennial sandmat. Given the comments of the observer that the plants are underwater much of the year, this could represent the first example of an emergent aquatic sandmat.

The thing that I find most fun about this is that Léon Croizat named the species Euphorbia duckei after Adolpho Ducke, likely having no inclination about the conditions under which the plants grew. The humor in this name may already be apparent to you, but I can't help but wonder if any future student will look at the plant and the habitat and use the associations with "duckies" as a way to help them remember the name.

Nelson (above) has contributed over 12,000 observations and nearly 10,000 IDs to iNaturalist so far, and tells me

In my opinion, iNaturalist is the most complete biodiversity data platform that best adapts to my objective, that is, to give visibility to my observations, so that the information contained therein is accessible for scientific studies and educational activities.

Through the direct collaboration of the participants, to whom I am very grateful, the use of iNaturalist taught me not only about the species I had observed, but also how to proceed and be more attentive in observing biodiversity.


- Another one of Nelson’s observations was chosen as Observation of the Day a few years ago. Take a look and then read his journal post about it.

The genus Euphorbia contains around 2,000 species, here are the most-faved observations of plants in this genus on iNat.

- Nathan has posted a ton of resources about euphorbias and other taxa, here’s a hub of links to some of his work.

- Nathan talked euphorbias and iNat on the In Defense of Plants podcast.

50% of all Vertebrates Observed!

We were looking back at this post from almost exactly three years ago when we announced that we'd tallied one third of all vertebrate species. We re-crunched the numbers and it looks like we're now at 50%! Here's the same breakdown by species group (apologies for switching the colors compared to the older figure, but we though it was a bit more intuitive this way)

We've broken 90% with birds with 9,761 of 10,560 species having been logged. And we are now above 50% for reptiles (6,824 of 11,350 species), mammals (3,322 of 5,818 species) and amphibians (4,317 of 8,229 species). The average is being brought down by the most diverse group fishes which includes the ray-finned fishes (10,158 of 33,128 species) and the other fish orders such as sharks and rays (602 of 1,427 species).

We're still logging a dozen or so new vertebrates a day, but we expect this rate to taper off as only rarer and rarer species remain. Any bets on how long it will take us to get to two thirds of all vertebrates?

A Marbled Polecat is Spotted in Mongolia! - (Bonus) Observation of the Week, 2/2/21

Our (Bonus) Observation of the Week is this Marbled Polecat (Эрээн хүрнэ), seen in Mongolia by @otgonbayar_tsend!

In the grand tradition of so many Observations of the Week, the observer - Otgonbayar Tsend - documented a species that is not in their main primary field of study, which I think speaks to the value of just being observant and curious about nature in general.

Otgonbayar is an ornithologist and currently works at a wildlife science and conservation center in Mongolia, but tells me he also “likes to take pictures of nature and wild animals.” When researching relict gulls in the western regions of Mongolia, he came across this marble polecat and was able to snap a few photos. “This animal was photographed in a very short time because it was moving so fast,” he recalls.

The only species in the genus Vormela, marbled polecats range from Eastern Europe to Central Asia and prefer dry, non-mountainous habitats. They’ll dig their own dens or utilize those made by other mammals and prey on various small mammals, both vertebrates and invertebrates. But due to loss of habitat and hunting in some areas, the IUCN lists this species as Vulnerable.

Otgonbayar (above, on the right) has only recently started using iNaturalist, and is part of a growing number of users in Mongolia (see below), led by @oyuna, @gundegmaa, and many others.

For his part, Otgonbayar says “I’ve learned more as I use iNaturalist. I'm happy to have the opportunity to share what I know with others, in addition to recognizing what I don't know.”


- Take a look at some pretty fantastic footage of marbled polecats.

- Lots of amazing plants in the Flora of Mongolia project, check out its most-faved observations.

- Having been born just a *bit* too early for the Pokemon craze, I had no idea Otgonbayar’s photo would make such a connection on social media when I shared it, but apparently this creature looks quite a bit like Zigzagoon.

Rest in Peace, Greg

Greg Lasley passed away on January 30th, 2021. Greg was a giant on iNaturalist, as one of our most prolific observers and most helpful identifiers, Greg made iNat a great place to be, starting way back in 2012 when iNat was a whole lot smaller. If you look at a map of all the observations he identified, you'll see he helped people all around the world.

We’ve written about Greg in the past, so if he helped you on iNat but you didn’t know him in person, check out Tony’s interview with Greg in 2018 or this Observation of the Week by Greg of a Golden-cheeked Warbler.

I thought the comments on this post would be a good place to share our memories of him. Please be polite and respectful, as Greg was dear to many of us.

I'll go first: in 2015 my friend @robberfly invited me to join a trip he was taking to tour the Rio Grande Valley area with Greg. It turned into a bit of an iNat-a-palooza, but I had a brief chance to get to know Greg in person. He was, of course, a naturalist with knowledge both deep and broad, but my lasting impression was of a consummate gentleman, as generous and kind to others as he was curious about nature. I don't think I heard him utter an unkind word about anyone on that trip, and it was obvious from talking to the many people we met how esteemed and loved Greg was all around the state.

Some random memories from that trip: he thought nothing of driving at 50 MPH in reverse down the shoulder of a state highway to check out some roadkill; he had a giant trash can in his car which I found perplexing and perplexingly useful; his green-boots-and-pink-shirt field combo was both practical and styling. He showed us all kinds of cool creatures, told us a few good (tall?) tales, and led us to some stellar BBQ.

I'll miss him, and my heart goes out to all his friends and family. He clearly inspired and encouraged many people to learn about and appreciate the natural world, both by example and by getting outside with folks and pointing things out, so I know he lives on in every life he touched.

A Japanese Mycologist and a Poison Fire Coral Fungus - Observation of the Week, 1/25/21

Our Observation of the Week is this Poison Fire Coral fungus (火炎茸), seen in Japan by @hirabe1216!

Hiroshi Abe has been fascinated with fungi since he was a child and ended up studying mycology in both college and graduate school. His focus is on the ecology of ectomycorrhizal symbiosis, “the strong relationship between tree species and mushroom forming fungi,” he explains. “I was really surprised to know tree species cannot survive without fungal symbionts in the natural environment.”

Since graduating, he has been studying fungi of nearby Komiya Park in Tokyo as a first step towards urban ecosystem conservation. 

I think even recording species with a short description and DNA sequence data will help us understand and evaluate the local natural environment. In addition, due to the fact that taxonomy of fungi is now just developing, undescribed species are found even in the local park!

Poison fire coral fungus, however, is a well known species, and Hiroshi (along with his friend Takahiko Koizumi) came across this specimen during their first exploration into Komiya Park. “This species is well-known as a lethal mushroom in Japan,” he tells me, “[and its] Japanese name is ‘火炎茸(kaen-take)’ meaning ‘flame fungus.’

It is also said that the number of [poison fire coral fungi] is increasing as oak wilt disease expands in Japan. Oak wilt disease, which triggers mass mortality of Quercus trees nurturing birds, insects and ectomycorrhizal fungi etc., is now one of the serious problems in urban ecosystems in Japan. In fact, dead Quercus trees attacked by the disease are increasing in Komiya Park.

Hiroshi (above) uses iNat to record and share his fungus explorations, look for observations made by others, and get ID help from the iNat community. “iNaturalist,” he says, “is the great first step of citizen-science!!”

(Some quotes have been lightly edited for clarity.)


- Poison fire coral fungus (also known as Podostroma cornu-damae) has devastating effects if ingested, you can read more here [PDF] if you’re interested.

- Once known mainly eastern Asia, it has been found as far a south as Australia. There’s even an iNat observation of one there.

- And because why not, here’s an electronic instrumental dance song named after this mushroom.

An Iranian Bird Guide and Bright Pink Native Plant - Observation of the Week, 1/19/21

Our Observation of the Week is this Bongardia chrysogonum (commonly known as سینه کبکی in Farsi) plant, seen in Iran by @shahrzadasa.

For nearly ten years now, Shahrzad Fattahi has worked as a bird guide, but she got her start in plants many years ago. “Iran is a country that is very rich in plant diversity,” she tells me, 

[and] at first I became interested in plants and I was able to take a short course to get acquainted with plants with taxonomy. Photography of nature was an integral part of my observations, so in the genre of wildlife photography and macrography, I expanded my activities and gradually became interested in birds and butterflies...I work and often travel alone to natural places and photograph the species observed, especially birds, butterflies and plants in different seasons.

It was on one of those trips, in 2016, where she took the photograph you see above.

During one of my trips to Mazandaran province, in a large plain called Lasem, which is full of flowers and butterflies in spring, I came across various plants, one of which was Bongardia chrysogonum

I remember a spring day with natural colorful flowers. A gentle breeze and a butterfly dance, along with the sound of a Common Rosefinch playing across the plains, thrilled me. After watching and photographing the species, I lay down on the grass for a short rest and watched the sky beyond the leaves, which attracted my attention more and I took two photos of it. I did not imagine that one day it could fit in a site like iNaturalist and be introduced to the public.

Shahrzad explains Bongardia chrysogonum grows in many of Iran’s natural areas, and its bright pink color attracts attention (the flowers are yellow when in bloom, however).  It’s commonly known as سینه کبکی, she tells me, which means “breast of the chukar” as it resembles that bird. The plant’s leaves, which are quite beautiful, as well as its tuber, are eaten and used medicinal purposes. A member of the barberry family (Berberidaceae), it ranges from Southeastern Europe into Kazakhstan, as well as North Africa.

After her friend @parham_beyhaghi suggested she share her finds on iNat, Shahrzad (above) signed up in 2017 and has posted over one thousand observations (and added 1,300+ IDs). She has been contacted by several students who are researching plants in the region, asking for information and photos, making her realize “how important this site is in introducing species and helping students and naturalists, and it can be a good communication bridge for exchanging useful information all over the world.

I am very happy to join this site so I can improve my knowledge and connect with other researchers and scientists of nature and use their information to learn. iNaturalist is a source of biodiversity learning in the world and it has made me much more interested than ever before.

Some quotes have been lightly edited for clarity and flow.


- Parham Beyhaghi was the subject of an early Observation of the Week, posted almost exactly four years ago!

- Bongardia chrysogonum has been traditionally used to treat urinary tract infections, and this study shows it may be effective in treating prostate issues in humans.

- It may also be an effective epilepsy medication, according to another study.

The First iNat Observation of a Rare Brazilian Viper - Observation of the Week, 1/12/21

Our Observation of the Day is the first Alcatrazes Lancehead (Araraca-das-alcatrazes) posted to iNat! Seen in Brazil by @diegojsantana.

Fittingly for someone who watched frogs and snakes while on fishing trips as a child, Diego Santana is currently a professor at the Federal University of Mato Grosso do Sul in Campo Grande, Brazil, where he works on the systemics and biogeography of reptiles and amphibians. Last November, he found himself on the Alcatrazes Islands, off the coast of Brazil, assisting researchers from the Butantan Institute, a large producer of immunobiological and biopharmaceutical compounds. The researchers were studying snake venom evolution and asked for Diego's assistance in finding and wrangling the island’s endemic viper species.

“We saw nine individuals in four days there and collected their venom, marked each individual with a microchip, and released them back to nature,” says Diego.

The island is beautiful, and to know that we were the only humans there with these incredible animals was an awesome sensation. We also observed two threatened frog species, which are also endemic to the island (Ololygon alcatraz [Scinax alcatraz on iNat] and Cycloramphus faustoi).

Alcatrazes lanceheads are known only from one island in the archipelago, Ilha Alcatrazes, which measures about 1.35 square km in area. The islands were previously attached to the mainland, and it is believed Alcatrazes lanceheads evolved from Bothrops jararaca snakes stranded there after the islands were cut off from the continent by rising oceans. Alcatrazes lanceheads are smaller than their mainland counterparts and feed primarily on centipedes and frogs as no rodents live on the island. Research shows that their venom is not particularly potent in mice, suggesting they have evolved to specialize in their resident non-mammalian prey. 

In the past, Ilha Alcatrazes was used for target practice by the Brazilian Navy but that’s no longer the case and Diego tells me “the island is within a conservation unit, is monitored constantly, and  access is granted only for research purposes (and it's not easy to get a license).”

Diego (above, assisting with a viper on Ilha Alcatrazes) says he heard about iNat from some friends and joined a few weeks ago and has been uploading photos from his archives as well as providing ID help on South American reptile and amphibian observations. “I really enjoy it and is one of my favorites hobbies now,” he tells me.

Slimelilies in the Algerian Desert - Observation of the Week, 1/4/21

Our Observation of the Week is this Albuca amoena plant, seen in Algeria by @zaidiabdelhamid!

“I am in love with nature as I like calm,” says Zaidi Hamid, who heads a department in Algeria’s Department of Forest Administration. “Since I was young, I like the calm that I discovered outside in nature away from pollution, far from the noise of the city.” Early on, he tells me he didn’t have the means to have a particular method for work and research, but since 2015 he’s  been researching wild plants of southwestern Algeria. 

“I see that information on the current plants in the region are very rare,” he explains. It’s made up of two zones, one called REG or the hamada and the other called the ERG. The REG is stony, while the ERG contains enormous sand dunes that reach 300m (984 ft) in height.

I saw that it is necessary to update [information about plants in this area] and to present it to the world because the plants of arid and Saharan regions are very different from the plants of other regions.

Furthermore, the plants of the Saharan zones have a high nutritional and therapeutic value for individual lives and society as a whole in the Sahara. (In our traditions, we use wild plants of our region as food and as medicinal plants more than anything.)

While driving back to his home city of Abadla nearly two years ago, Zaidi saw Albuca amoena plants in flower, so he stopped and photographed them with his smartphone, taking about 30-40 shots. “After photographing Albuca Ameona, I had an indescribable feeling for the way that I captured these images without specialized photography equipment,” he tells me. “Even if our means are limited, we do not do not lose hope of achieving our desired goal.”

Plants of the genus Albuca are commonly known as “slimelilies” in English, as they exude mucous-like slime. The mechanism of pollination for this genus has been a bit of a mystery, as the tepals of its flowers close tightly over the stigma, which is where pollination usually happens. Steven D. Johnson, et al, found that in Albuca canadensis and Albuca setosa, which occur in southern Africa, large Megachilid bees deposited pollen from their backs onto the tips of the tepals. The pollen germinates from liquid exuded by the plant, and when the flower wilts the tepal brings that to the style, pollinating it. If you’re having a hard time picturing how this works, check out the excellent diagram (Figure 4) in the Discussion section of their publication, which is available here.

Joining iNat just last month on the recommendation of @karimhaddad, Zaidi (above), says 

It was a great honor for me to join it to enrich my knowledge and to join the group of scientists and researchers in the field of nature.

iNaturalist changed my view of research, especially the way to photograph plants and nature in general.

iNaturalist is truly a world that brings together naturalists and scientists that one can trust in, and I am very honored to have joined them.

(Zaidi's text was translated from French by Marité Xavier)


- Zaidi also photographed this gorgeous Colchicum gramineum on the same day he saw the Albuca amoena!

- Here are the most-faved observations of this genus.
