Diplachne fusca (L.) P. Beauv. ex Roem. & Schult. ssp. fascicularis (Lam.) P.M. Peterson & N. Snow[HC2]

Origin: Native

selected vouchers: WTU

Notes: FNA24: "Leptochloa fusca subsp. fascicularis extends from southern British Columbia and Ontario to Argentina, although it has not yet been reported from Georgia. Coastal populations from Massachusetts to Florida with long lemma awns have been called L. fascicularis var. maritima (E.P. Bicknell) Gleason. They do not merit taxonomic recognition because long awns and salinity tolerance are common throughout the species.

Leptochloa fusca subsp. fascicularis differs from L. viscida, which grows in the same region, in its longer panicles, frequently unawned or mucronate lemmas, and whitish florets."
