Discussion

Variety lactea is the most common and conspicuous Drymocallis at higher elevations in the central and southern Sierra Nevada, where it is recognized by its large cream-white to yellowish petals and narrow inflorescences. It also occurs in the San Jacinto Mountains and Transverse Ranges of southern California, and extends into the Intermountain Region from the mountains of southeastern Oregon to central Nevada.
