NEED IN SITU PHOTOS. Lemmon's rockcress, a tundra plant, is called “common” on Stony Pass. Elsewhere there are only two collections from the Watershed: NE of Bristol Head summit (Mineral Co), and 0.5 mile E of the Continental Divide above Eldorado Lake (San Juan Co). FNA notes that currently the species embraces both sexual and apomictic specimens, and may need further nomenclatural division. So named, Boechera lemmonii is present in all USA states W of the Great Plains except for Arizona and New Mexico.
