» Life History
Populations of Barneby reed-mustard occur in Emery and Wayne Counties, Utah. Populations have been know to occur on the Moenkopi Formation, Kaibab Limestone and on the Carmel Formation. This species is found growing on coarse soils derived from cobble and gravel river terrace deposits, or rocky surfaces at 4,800 to 6,500 feet in elevation. Barneby reed-mustard can be found growing with other desert shrubland plants including shadscale, Indian ricegrass and pygmy sagebrush.
We have little information on the biology and life history of Barneby reed-mustard. Plants reproduce sexually and flower from late April to mid or late May (Welsh and Neese 1984). Gravity, wind and rain are thought to be the primary dispersal agent of seeds (Welsh and Neese 1984).
This species looks similar to Schoenocrambe argillacea. Barneby reed-mustard is slightly larger and its leaves are elliptic to oblancelate with fewer flowers. The two species can be difficult to tell apart when they are small.
