bouteloua | Lantana horrida |
numerous misIDs with Lantana urticoides due to common & sci name synonymy |

Many reference books call Texas lantana (by which I mean the horrid-smelling species with smallish leaves and yellow and bright orange flowers) Lantana horrida, so this conundrum isn’t confined to iNat. Add to it the difficulty of distinguishing reddish-orange varieties of Lantana camara from the native species and it’s surprising that anything found in Texas isn’t classified in observations here in iNat and elsewhere as Lantana horrida.
For those reasons, I’ve despaired of even trying to clasdify observations of these two species beyond the level of genus.
Time spent in the Devil's River/Del Rio/Amistad area in the past year allowed us to see native Lantana urticoides in its natural setting, far from any L. camara influence.

Chuck, I’ve seen some plants in a landscape on Lakewood Drive just west of 360 that are dead ringers for these but smell just like Lantana camara. The color is right, the leaves are the right size, and the dentition is right (fewer, larger teeth and more rounded tips), but the odor is almost pleasant. So am I mistaken about the aroma of Texas lantana, or do we have a stealthy invasive species?
On the other hand, is it safe to classify all lantanas with larger leaves and many, fine teeth (more serrate than dentate) as nonnative, invasive plants?
This is a problematic group to ID for all of us: In particular, when it comes to plants, I have poor odor discrimination. Plants either don't smell, or they are "fragrant" to my undiscerning nose. (The various aromas of Hedeoma are virtually lost on me.) I'll have to go out and crush some leaves, but I will be a poor observer of that aspect.
Moreover, although leaf shape and dentition are useful, these are quite variable among the species and of little use for any individual plant. Finally, the details that Palmer uses in his recent revision of this group of Lantana species are excruciatingly archane--like variation in the types of hairs on the upper and and underside of the leaves and their distribution over the surfaces of the leaves.
And they all hybridize and there are cultivars running amok.
Jeez!
No, I wouldn't say it's not possible to find the native urticoides in the Austin area. Some plants out "in the wild" may approach native phenotype; I think we are within its natural range. But there will be various cultivars and versions of "Lantana camara" which have escaped...including some with yellow & orange flowers.
Just carry your 100X field stereoscope in your backpack when you hike around and the differences of the harriness on the underside of the leaves will be very apparent after you look at every leaf. ;-)
As of July 11th, 2019 I think there were about 1,300 observations of L. horrida on iNat.
As said above, most of these are Lantana × urticoides or L. camara or hybrid origin.

@bouteloua, my inclination would be to back them up to genus unless I'm sure they're Lantana camara. Is that OK with you?
Here's what I just added as a comment with a genus-level ID:
Lantana horrida is now reserved for a species that doesn't occur in the United States. The native (to Texas) plant commonly called Texas lantana is now classified as Lantana x urticoides, but so many orange-and-yellow cultivars of the commercially introduced L. camara (or hybrids of that cultivar with L. x urticoides) are out there that I have despaired of identifying them beyond the genus. (Everything I thought I knew about Texas lantana turns out to have been incomplete, if not wrong.)
Customize as desired, if you wish.
Still around 500 observations of Lantana horrida in the US. And a lot outside are probably other species too. But here's the link to reidentify in the US:
https://www.inaturalist.org/observations/identify?quality_grade=casual%2Cneeds_id%2Cresearch&taxon_id=243637&place_id=1
And a link to help refine genus observations to species if you're able (I'm definitely not...):
https://www.inaturalist.org/observations/identify?quality_grade=casual%2Cneeds_id&ident_taxon_id=243637&place_id=1&lrank=section
Currently around 260 observations out of range, 130 in the US. Big improvement but still work to be done!
No idea who's gonna help with all the Lantana IDs that are actually within the range of horrida? Most of those are probably misIDed too.
Too many honey-dos! My wife has gotten used to seeing me at home, so now she thinks she can give me all kinds of tasks: "Wash those dishes! Clean out the garage! Shampoo that carpet! Clear a path into that wilderness where some people would have a back yard!" She really gets on me about it. Some of these things she's reminding me of again, and it hasn't even been six months since she last mentioned them!
:-D
Lantana urticoides
has a synonym L. horrida Moldenke* has synonyms L. horrida f. bracteosa Moldenke and L. horrida f. latibracteata Moldenke.Lantana horrida Kunth is apparently also a valid species. Unfortunately L. horrida on iNat was given a common name "Texas Lantana" and as a result of that + the sciname synonymy, there are a ton of IDs of L. horrida in the US on iNat, where the species isn't known to occur. I removed that common name from L. horrida. But I don't know this taxon well enough to add species or lower IDs to it.

*(as of July 2019, L. horrida Moldenke is no longer listed on POWO as a synonym)
