Draba serpentina

It is endemic to Nevada in the United States, where it occurs in the Snake Range in White Pine County and the Toiyabe Range of Lander County.

[1] Until 2007 this taxon was treated as a variety of Draba oreibata.

The two were separated because they are different in morphology, in chromosome number, and in distribution, as they grow over 480 kilometers apart.

[1] This is a small cushion-like plant with stems 3 to 13 centimeters long.

It has up to 14 white flowers in its inflorescence, each with petals 5 or 6 millimeters long.
