Taxonomic Notes
Varieties: A. americana var. americana; A. americana var. turrigera[1]
Synonym: Glycine apios[1][2]
Description
A. americana is a dioeceious perennial that grows as a forb/herb or a vine.[2] As a vine, it can reach 1-6 m in length[4] and produces maroon or reddish-brown pea-like flowers in compact racemes arising from leaf axils. Leaves are green and alternate.[3]
Distribution
This species occurs from Nova Scotia, New Brunswick, and Quebec, westward to Minnesota and South Dakota, southward to southern Florida and Texas.[1] The plant can also be found cultivated in Europe.[5]
Ecology
Habitat
A. americana occurs in marshes (tidal and non-tidal), wet thickets, streambanks, and bottomland forests.[1] In Washington D.C. marshes, relative cover of vegetation in reference sites was 1.60% and the relative density of seedlings emerging from seed bank samples was 1.12%.[6]
Phenology
In the southeastern and mid-Atlantic United States, flowering occurs from June through August and fruiting from July though September.[1] On the Florida panhandle, flowering has been reported in April and June through Septemeber, peaking in August and September.[7]
Fire ecology
In southern Illinois brown shale barrens, Apios americana was absent in preburn sampling but present postburn, suggesting the species may require, or at least do well, in frequently burned habitats.[8]
Pollination
The only legitimate pollinator known for A. americana are bees of the family Megachilidae.[5]
Use by animals
The cord-like rootstalk contains edible tubers that have been eaten historically by Indians and the Pilgrims in soups, stews, or fried like potatoes. Cooked seeds can also be consumed by humans.[3]
Diseases and parasites
In Baton Rouge, Louisiana, cucumber mosaic virus and Desmodium yellow mottle virus are reported to be causal agents of diseases in A. americana.[9]
