Chilean brome, Bromus trinii (B. berteroanus in FNA, v.24:223-224)
Known from a serpentine outcrop in area H adjacent to the abandoned exclosure, until a second station was found March 4, 2007, several plants in bloom just a few yards east of the extensive Allium falcifolium area UTM 0568637, 4140177; Sector 24, upper 4B. In April 2010 it was found along trail 15 and also Rd F in serpentine. This pilose annual plant has a long awn (13+ mm) arising from the sinus of acuminate lemma teeth and the first glume has a single vein. Lemma backs are more or less rounded. The characteristic awn bend and twists is apparent in dried specimens.
