Taxonomic Notes
Synonyms: Glycine apios Linnaeus. [1]
Varieties: Apios americana var. americana; Apios americana var. turrigera Fernald[1]
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] The legume fruit is indehiscent and with usually 1 seed, and the seeds are oblong or square in shape with a dark brown wrinkled surface.[2]
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] and has been observed along the borders of bodies of water and wet flatwoods, in loamy sand and calcareous soil, and in disturbed areas like roadsides.[6] It has been reported as common in a lakeshore cypress swamp on the east side of Lake Arbuckle, Polk County, FL.[7] 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%.[8]
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, A. americana has been observed flowering in April and June through September, with a peak inflorescence between August and September.[9] Flowering in large numbers during the winter month of January has been reported in the central peninsular Florida Polk County.[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 burned habitats.[10] A different study in Michigan white pine/red pine stands showed the mean percent coverage was greatest when burned once (1.62%) over a five year period (1991-1995). Biennial burn frequencies had a mean percent coverage of 1.09% and unburned areas covered 0.29%.[11]
Pollination
The only pollinator identified for A. americana are leafcutting bees from the family Megachilidae, though it has been speculated that they are fly pollinated.[5]
Herbivory and toxicology
This species has been observed to host Lygus lineolaris (family Miridae).[12] A. americana has been found to be consumed by white-tailed deer, but not commonly.[13]
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.[14]
Conservation, cultivation, and restoration
Cultural use
The cord-like rootstalk contains edible tubers that have been eaten historically by Native Americans and the Pilgrims in soups, stews, or fried like potatoes. Cooked seeds can also be consumed by humans.[3] It was a food source for multiple Native American tribes, including the Omaha, Dakota, Santee Sioux, Cheyenne, Osage, Pawnee, and Hidatsa. Groundnuts were eaten raw, cooked, dried, or even ground for flour. As well, the rhizomes were stored by boiling, peeling, and drying them, and the seeds are cooked and eaten like peas during the summer.[2][15]
