Evidence against the existence of varieties in Arctagrostis latifolia ssp. arundinacea (Poaceae)
The morphological diversity of North American specimens of Arctagrostis latifolia ssp. arundinacea (Trin.) Tzvelev was evaluated for possible varieties within the subspecies by considering (i) descriptions of three previously recognized taxa included in the subspecies, (ii) measurements of spikelet...
