How to know the Texas Arabideae (Genera Draba, Abdra, and Tomostima)
Species of the Tribe Arabideae are among the first flowers to bloom (January--March or early April). Being small and inconspicuous, they are often overlooked (especially Draba reptans). Observations of Texas Arabideae are here. These species have been lumped and split, taxonomically; recently, all were in the genus Draba. The following characteristics vary, so documenting multiple characteristics will confirm the ID. Features to capture include:
- side view of mature fruits (pods)
- side view of flowering stem (pedicel) from top to bottom (with hairs in focus)
- view of leaves
Also, young plants may be challenging or impossible to identify.

*There is also a yellow-flowered species in Jeff Davis county (Trans-Pecos): Draba standleyi

Thanks - I’ll be prepared for these this year!
Whew. I remember trying to wrestle with Draba a while back and getting super confused... I think it was mostly youngsters that I was trying to ID (before fruits developed).
Anywho, great journal entry again, Russell! :) Thanks for curating these genera!
Ahhh... I missed this post. It was probably during my forced holiday break. Bookmarking!
Ah, thank you! I'm bookmarking, too!
Just ran across this and it helped me with an identification recently, thank you for putting it together!
