Potentilla basaltica

• http://www.calflora.net/botanicalnames/pageBA-BI.html

basal'tica: of or from basaltic regions or soils. David Hollombe contributes the following: "Potentilla basaltica occurs near the head of the west arm of the Black Rock Desert, named for the dark pinnacle at the south end of the Black Rock Range known as Black Rock Point. The point owes its color to a cap of basalt rock. Our specific epithet is intended to honor this seemingly desolate area of Nevada." (ref. Potentilla basaltica)
