Clarkia is my favorite group of plants (and basically the only ones I can identify)! I'm currently a graduate student working on a phylogeny for the genus Clarkia. I am also researching the evolution of pigmentation patterns in the same genus.

I'm currently working on making some guides to identifying Clarkia:

These guides are a work in progress, so message if you have suggestions!
