Discussion
In subsp. lasiocarpum there is considerable variation in the density and location of trichomes on the fruit valve; in some populations (e.g., Rollins & Munz 6741, GH), the trichomes are present over the entire valve; in others they are restricted as a fringe along part of the fruit margin.
