Schistophragma intermedia (A.Gray) Pennell

A summer annual of extreme southwestern New Mexico and adjacent Arizona that can be abundant in wet years. Most specimens are collected along sandy washes and are 2-3" high. When visiting the Peloncillo Mountains in late summer in 2007, however, I found this species abundant on many small gravel catchments on exposed igneous slopes. Although abundant, the plants were quite minute, most less than 1" in height.

Plant habit near Mormon Pass in the Peloncillo Mountains, Hidalgo County, New Mexico, 26 Aug 2007.
