Barneby reed-mustard, Schoenocrambe barnebyi, is a Federally listed endangered plant that is a narrow endemic to (is found only on) the Colorado Plateau in Emery County and Wayne County, Utah. A member of the mustard family, this species is a perennial herb that is 10-25 cm tall. Specimens have a branched woody base that gives rise to purple veined, white, or lilac flowers from late April to early June. Barneby reed-mustard grows in xeric, fine textured soils on steep eroding slopes of the Moenkopi and Chinle formations. It grows in sparsely vegetated sites in mixed desert shrub and pinyon-juniper communities, at elevations ranging from 1460 to 1985 meters. Uranium mining has impacted this plant in the past, and trampling by hikers is a potential problem at some locations.
