Apios priceana
Template:Short description Template:Speciesbox
Apios priceana is a rare species of flowering plant in the legume family known by the common names Price's potato-bean, Price's groundnut, and traveler's delight. It is a climbing yellow-green vine growing from a stout, potato-like tuber. The plant is native to the Southeastern United States.
Description
The vines may be up to Script error: No such module "convert". long. It has a large underground tuber, distinguishing it from other Apios species. The leaves are alternately arranged on the stem, about Script error: No such module "convert". long, and comprising seven leaflets. The fragrant pale pink or greenish-yellow pea-like flowers bloom in the summer.[1] The fruit is a long slender pod about Script error: No such module "convert". long.
Distribution and habitat
The plant is native to the U.S. states of Alabama, Mississippi, Kentucky, and Tennessee. It occurred in Illinois in the past but its population there was destroyed.[2] It is usually associated with openings in the forest canopy in mixed hardwood stands where ravine slopes grade into creek or stream bottoms.
Ecology
The flowers are pollinated by bees and the long-tailed skipper (Urbanus proteus).[1]
The threatened status of the species is primarily due to habitat destruction, but other impacts such as disease, predation, and historical tuber collection have also contributed.
Conservation
With about 50 to 100 known occurrences,[2][1] the plant is federally listed as a threatened species.[3][4]
Uses
The plant was probably used as a food source by Indigenous peoples of the Americas and early white settlers.[2]
