Discussion
Variety megalopetala is known from the southern Sierra Nevada from Mono and Tuolumne to Tulare counties. It tends to be the largest of the three varieties, with plants having larger flowers and longer and narrower leaflet lobes, which commonly have apical setae to 0.5 mm. Variety megalopetala is also more likely to occur in wet meadows along subalpine streams.
