These flowers appear to have not bloomed yet. As a result I am having trouble identifying. Catherine Creek Trail. April 27, 2013.
Possibly Eriogonum umbellatum. Nope, not that -- not on the cheatsheet. Maybe the Eriogonum strictum one mentioned.
Nope, leaf is a good match. Would like to see it develop for another week or so to see if the inflorescence expands.
