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.
