Aira elegans Willd. ex Roem. & Schult.
Stem: 9--35 cm, generally glabrous. Leaf: sheath and ligule glabrous to slightly scabrous. Inflorescence: > 1.5 cm wide, open, branches not equal; spikelet stalk 2--8 × spikelet. Spikelet: 1.5--2.5 mm; glumes 1.5--2.5 mm; lemma +- 2 mm, awn +- 3 mm. Chromosomes: 2n=14.
Ecology: Sandy to clay soils, open sites; Elevation: generally < 400 m. Bioregional Distribution: NCoRO, n SNF, ScV, SnFrB, w WTR, PR; Distribution Outside California: to Washington, eastern and southern United States; native to southern Europe. Flowering Time: Apr--May Note: Also treated as Aira caryophyllea var. capillaris Bluff, Nees & Schauer, Aira elegantissima Schur, Aira pulchella Willd. Until the taxonomy of these European species is more clearly understood, it seems best to use Aira elegans as in Wipff 2007 FNANM 24:615--617.
Synonyms: Aira elegantissima Schur; Aira caryophyllea L. var. capillaris Bluff, Nees, & Schauer; Aira pulchella Willd.
