I thought the complexity of branching of the bracts was more like domestic carrots than typical wild carrots, but there's variation in that.
You piqued my interest. I was able to find a key to the subspecies of D. carota in the Flora Europaea. The distinguishing factor for the two subspecies in question here is the fleshiness of the root, which unfortunately is not shown in this photo. I can say that all the carrots I pulled at this property had thin, white roots, not the thick roots seen in subsp. sativus.
This species is provincially blue-listed (of special concern). When you see whitebark pines, it's worth uploading several photos of one in the iNaturalist observation, to show more features. The BC Conservation Data Centre folk appreciate receiving current records.
@judithofsquamish Thanks for your remarks about uploading photos of whitebark pine. My citizen science project incorporates iNaturalist and I have included some tips on taking and uploading photos of whitebark pine on the project website here: https://elfinwoodecology.org/the-whitebark-pine-project/
On Plantago media. Specimen deposited at the Royal Alberta Museum.
Basal part of the elytra are more shining than the apical, and the punctures are larger at the base, with shining spaces between them (see: https://bugguide.net/node/view/35674).
@ianswift Would you mind taking a look at this one as well? Not very many observations from western Canada. Thanks!
Hi Peter. I know there are both C. flavescens subspecies hirta and C. rubra at this location. Henry Conner states in the grass flora that north of the distribution of C. rigida, plants resembling C. rigida are often hybrids between the two aforementioned species. Your plant has quite distinctly rolled leaves which suggests to me there is some C. rubra in it, but the other features match for C. flavecens subspecies hirta except leaf width, which could also be explained by the C. rubra influence. C. rigida shouldn't have such strongly rolled leaves I don't think.
Hi @rowan_hindmarsh_walls, thanks! That makes sense. When keying this plant, I indeed struggles a bit with the strongly u-shaped leaf lamina.

Thousands of juveniles in a freshwater pool at the end of rocky run. Pools were outside of tidal influence by a long way, but in range of sea spray.
Thank you! I forgot to bring my waterproof camera so had to suffice with S22+ camera from above, the lighting was shocking. I'm just glad that I could get some shots of the critters in focus.
I think this gives some insight into the reproductive ecology of the shrimp - I'd bet money that they directly develop to prevent them from washing out of the creek.
The pools I found them in were essentially the last freshwater along the creek before a sharp drop of about 4-5m into the ocean.
I forget the author, but remember reading a paper on genetic and life history differences between headwater and lowland paratya. The former directly develop to stay upstream, while the latter produce larva that join estuary plankton and subsequently migrate back in to freshwater. The latter would be impossible in this case.
or maybe spicata.
For me, the bark plating pattern is a good match for Sugar Pine, as Western White Pine when old, typically has more of a rectangular grid-like pattern with smaller plates, although it can be a similar color. But who knows, maybe I haven't seen enough examples.
Zooming in on the cones: The cones are held at angles instead of hanging straight down as is common on sugar pine, and those cones seem smaller than what you would expect with sugar pine.
It looks like the location on the map is incorrect. Can you edit the observation to reposition the map pinpoint? You can do this by zooming in on the map within the mobile app or by editing on the website and tapping/clicking where it was observed. You indicate a "general area" by dragging one of the points around the circle further from the center point to as accurate a location as you can estimate. If you don't want to reveal the exact location, you can also select “obscured”, which will only display the approximate region and not the precise map pinpoint.

@amr_mn
I wonder if Sinanodonta woodiana is the only freshwater clam like this observed in Europe. I'm also curious about what distinguishes it morphologically from other species of the genus Sinanodonta.
@pintail As we've discussed before, the Sinanodonta invading Europe appears not to be S. woodiana sensu stricto, but a cryptic species originating in the Yangtze that currently has no correct name:
Bolotov et al (2016) called this "Temperate Invasive Lineage"
Kondakov et al (2018) called this "cf. gibba"
Lopes-Lima et al (2020) called it "cf. woodiana 1".
Further, genetic studies have shown that all the European Sinanodonta are this same species.
With that background, Yes, Sinanodonta cf. woodiana is the only Unionid like this in Europe. The native European species most similar are all in the genus Anodonta. They have very fine umbonal rugae.
They rarely have rays, or reddish tones in the periostracum.
They rarely have pink tones in their nacre.
They are rarely as inflated as S. woodiana often is.
Their umbos barely rise above the hinge.
Their shapes aren't as round as S. woodiana.
There may be some overlap in shape between the roundest Anodonta and the longest S. woodiana.
I don't really know how to tell the difference morphologically between different species within Sinanodonta. In Europe, one doesn't have to: they're all S. woodiana... At least until someone publishes a peer-reviewed paper that says otherwise and assigns it a name.
I should also note that the above discussion of Europe excludes the Volga River system of Russia, where S. lauta has also been introduced in addition to the "S. woodiana" that has been introduced to the rest of Europe.
@pintail The difficulty in separating species within Cristariini is why I have rarely added any identifications to your observations in Korea.
@amr_mn
Thanks for the detailed explanation.^^
and
I always forgot about freshwater clams because I didn't think about them.
The species I call Sinanodonta lauta in Korea is Sinanodonta woodiana cf. 1 bunch.
And the Sinanodonta woodiana I mentioned is a group that was recorded as "Sinanodonta woodiana cf. 2" in a previous paper.
Then, the species recorded as Sinanodonta woodiana in Europe seems to be the same group as the species I talked about as Sinanodonta lauta in Korea.
@pintail Yes, S. lauta and "S. cf. woodiana 1" were each others' closest relatives in Lopes-Lima et al (2020).
If S. woodiana is split (as it appears will happen), the name will apply to "cf. 2" as it was first described from Canton, China. So all of the Sinanodonta in Europe will get a new name.

In the above paper, freshwater clams in Greece were studied. The Sinanodonta woodiana recorded above had the same gene sequence as "Sinanodonta cf. wooodiana 2".
And the appearance is also similar to the object with the same sequence as "Sinanodonta cf. wooodiana 2" in Korea.
@arm_mn
If you give me an email address where I can receive the picture file, I will send you the phylogenetic tree and fas file I drew last year.
@pintail I'll have to re-read the sources... I may have written "cf. 1" when I meant "cf. 2".

@jokurtz Just wondering if this should be reassessed. This was the first or second I shot from this location five years ago. I've shot about 20 more in the past five years here and all that went to research grade grade ID'd as Rough Blazing Star (L. aspera).
You are one of the ID'ers on several of them.
Here are my later observations. Maybe they will help. Or maybe we have two species at this nature area :)

Thanks!
@bpagnier
This one would suggest that Kuebler Langford Nature Area has two species and one ssp all growing in the same area. This area is so small that if you stood on a 5 gallon bucket you could probably see them all, which last year was maybe 25 specimens at best (the most I ever saw there). Not questioning your knowledge here but really would like to nail it down if in fact this is the case. Some I have found here have yet to be ID'd.

Thanks for all the help on these!
@bpagnier
Very interesting results from those you went through, which I think were all of them. These were all found in controlled burn areas in three different reclaimed prairie areas. Most from Kuebler Langford, some from Pickerel Lake and some from Halfmoon Lake. They are all within hiking distance from each other but distinctly different controlled burn areas within Pinckney Recreation Area. I read you profile and it seems you are well versed in this area. I hope you don't mind me asking.
Do you think that most Blazing Stars in these reclaimed areas are reintroductions by the DNR. If so, in your state is there an attempt to reintroduce the exact species that was there 100 years ago for example? Assuming these are reintroductions, do you have any idea of why they'd introduce two different species just 15 miles apart? Liatris scariosa var. nieuwlandii is an anomaly in that it was found within an area with all the others being Devils Bite.
Thank you!
