Stellate Pubesence

Taking a break from sedges and practicing on Lesquerellas, this is Lesquerella gordonii which got picked for practice because any two of its stellate arms may be fused at the base and therefore termed bifurcated.

I need to do better. I had to use software to enhance the image. It get dark fast at this magnification.

But that aside, I have always found that using the vestiture of Lesquerellas as a key character is aggravating. That's becasue on any given specimen there will be lots of variation in the hairs.

Actually, since I have a bunch of different ones of these, I may do a little comparitive series on their hairs.

Dana is sending me a specimen of that endangered south Texas one to photograph its hairs. It used to be called Lesquerella thamnophila, but apparaently someone has put it in a different genus for the nonce. Zapata bladderpod, ye know.

I also have several Lesquerella specimens that are not keyed out to my standards, and I wouldn't mind someone else's opinion on, whut they are.

Speaking of mustards, how are your bracted twist flowers doing?
