Polypogon interruptus Kunth[FNA24, HC, HC2]
ditch rabbit's-foot grass

Publication: Nov. Gen. Sp. (quarto ed.) 1: 134, pl. 44 [1816]. 1815.

Origin: Introduced

selected vouchers: WTU

Notes: We follow several floras (e.g., Jepson 2nd, Intermountain Flora), which treats this as native to South America, but see comments from FNA below.

FNA24: "Polypogon interruptus grows in moist soil at lower elevations. It is native to the Western Hemisphere, extending south from the western United States into northern Mexico, and through the American tropics to Argentina and Bolivia. The more eastern records may indicate introductions; it is not known whether or not the species persists at these locations."
