Scanned from specimen found near Arlington, Maricopa Co., Arizona. May 1, 2008

WINTER-SPRING ANNUAL : Low growing tufted grass mostly less than 20 cm tall.

LEAVES Narrow blades. Notice long hairs at ligules.

RANGE : Fairly common in mostly agricultural areas of the Sonoran Desert of Arizona.

FLOWERS: Small spikelets on narrow spiked inflorescence. Distinguished from similar Schismus barbatus by high magnification (10x) of the floral parts: The glumes are slightly longer (6mm) and the lemmas are hairy on the back and have a 0.5 mm to 1 mm notch in tip. The two species may intergrade.
