Anemone, anemone, wherefore art thou?

For those of us eager to get a jump on documenting spring wildflowers, the anemones are beginning to bloom here in Texas. There are five species in TX, but most aren't well documented. Anemone berlandieri is the most common. I'm hoping we can fill in the gaps for the less commonly observed species.

Here's a guide to the features that need to be clearly visible in pictures to make a positive ID:

Here's a map showing iNat observations of all 5 species of Anemone occurring in Texas (In the overlay panel, toggle off A. berlandieri as it obscures some of the others)

Anemone caroliniana can occur together with A. berlandieri, sometimes growing side-by-side. But A. caroliniana is far less common, and seems to prefer sandy soils.

Anemone okennonii was described as a new species in 1994. Many new observations of this species added in 2019 contribute to our understanding of its geographic range.

Anemone edwardsiana has a distribution limited to the limestone outcrops of the Balcones Escarpment. It appears to prefer canyons where it is relatively more moist. This species could be better documented, so those exploring the Balcones Escarpment during March should watch for this species--especially between Concan and Boerne and the vicinity of San Marcos.

In Texas, Anemone tuberosa is found only near El Paso at least as far east as Hueco Tanks State Park. (Note: A. okennonii was elevated from within A. tuberosa, so older literature includes the range of A. okennonii in the range of A. tuberosa.

Please tag anyone who you think might be interested in making Anemone observations!
