GENUS INDEX

GENUS CODE: ARIST
GENUS SCIENTIFIC: Aristida
GENUS AUTHORITY: L.
GENUS COMMON: Threeawn
GENUS SUMMARY: A genus of about 250-300 species, widespread in the tropics, subtropics, and warm temperate zones. Cerros-Tlatilpa, Columbus, & Barker (2011) disuss the phylogeny of the genus.
GENUS IDENTIFICATION: Identification notes: The awns must be dry and relatively mature to assume their characteristic positions (immature awns and moist mature awns are erect and parallel). It is sometimes useful to dry a collection unpressed. Beware, however, that drying followed by dispersal can take place very quickly under the right conditions (such as the dashboard of a hot car)!

FAMILY INDEX

FAMILY CODE: POACEA
FAMILY SCIENTIFIC: Poaceae
FAMILY AUTHORITY: (R. Brown) Barnhart 1895 or GRAMINEAE A.L. de Jussieu 1789
FAMILY COMMON: Grass Family
FAMILY SUMMARY: A family of about 771 genera and 12,074 species, herbs (and some shrubs and trees), cosmopolitan. Tribal classification largely follows FNA (2003a, 2007a), with some changes based on subsequent research, as for instance in the Chloridoideae (Peterson, Romaschenko, & Johnson 2010a).
FAMILY REFERENCE: Flora of North America Editorial Committee (2003a, 2007a)=FNA; Hitchcock and Chase (1950)=HC; Blomquist (1948); Peterson, Romaschenko, & Johnson (2010a, 2010b). Key to genera adapted in large part from FNA.
