The fruit is a cylindrical legume 13—20 cm (5—8 inches) in length. Flowering occurs from mid-June through August, with fruits present from late August through September (Kral 1983, Medley 1980, Woods 1988). This species can be distinguished from Apios americana (ground-nut), the only other North American species of Apias, on several taxonomic characters. Most notable is thesingle large tuber of Apiospriceana, as compared to the multiple small tubers in Apios americana. Apios priceana typically has larger leaves, more leaflets, and longer fruits. The standard petal (uppermost petal) is more yellow-green than purplish-maroon (as in Apias americana), and has a fleshy mucro-like appendage at its tip (Kral1983, Medley 1980, Woods 1988). Apios priceana is of potential economic importance as a food crop. Its large single tuber is edible (National Academy of. Sciences 1979, Walter et a]. 1986) and it may have been a food source for Indians and pioneers (Medley 1980), as was the more common Apios americana (Yanovsky 1936, National Academy of Sciences 1979, Seabrook and Dionne 1976). Walter (et a]. 1986) suggests that Apias priceana is perhaps or loss of habitat through cattle grazing! most valuable as a source of germ plasm trampling, clear-cutting and succession. for breeding with other Apios species.
