Price's Ground Nut was first collected by Sadie Price in Kentucky in 1896 (USFWS 1993). The plant is an herbaceous, perennial vine that grows from a stout, thick tuber. Apios priceana blooms from mid-June through August, producing clusters of fleshy greenish-white or brownish pink flowers. Fruit is set in late August through early October.
A. priceana has potential value as a food source for humans. The plant produces large single tubers which are edible and may have been used by Native American Indians and early settlers as food (Walter et al. 1986, USFWS 1993). However, A. priceana may be of greatest value as a source of germplasm for breeding with other Apios species.
Distribution & Occurrence
A. priceana occurs in open woods and along wood edges in limestone areas. Several populations grow along highway rights-of-way and powerline corridors. Soils are well-drained loams on old alluvium or over limestone (Kral 1983).
Often associated with Acer saccharum, Amphicarpa bracteata, Campanula americana, Cercis canandensis, Lindera benzoin, Quercus muhlenbergii, Tilia americana, Toxicodendron radicans, and Ulmus rubra (USFWS 1993).
|A. priceana is currently known from 25 sites in fifteen counties in four states. Most of these sites contain fewer that 25 individuals.
Counties include: Alabama: Autauga, Madison, and Marshall counties. Kentucky: Nelson, Livingston, Edmonson, Warren, and Hickman counties. Mississippi: Chickasaw, Clay, Kemper, Oktibbeha, and Lee (Coonewah Creek Chalk Bluffs Preserve) counties. Tennessee: Montgomery, Davidson, Williamson, Grundy, and Marion counties (USFWS 1993). The plant was reported from Illinois in the past, but is now considered to be extirpated from that state.
Conservation, Ecology & Research
Habitat loss due to highway maintenance and cattle grazing and trampling
Logging (clear cutting)
Succession (leading to a closed tree canopy)
Germination protocols have been established (incisions made in seed coat and incubated at 70 degrees Fahrenheit).
search for and establish new populations, research all aspects of life history research (pollination ecology, seed production, germination, seedling recruitment and survival).
