Description
"Annual or perennial herbs. Stems erect, teret, often in clumps. Leaves opposite, entire, sessile to short-petiolate. Flowers solitary or in congested cymes, pedicellate or sessile. Calyx 4-5 lobed, tubular; corolla cleft ½ or less its length, campanulate, funnelform or tubular, lobes the same number as the sepals, often connected with a thin tissue (pleats); stamens 4-5, anthers free, or coherent in a ring around the style; stigmas erect, recurved in age, style short or absent. Capsule laterally compressed, elongate, stipitate; seeds 0.6-2.2 mm long." [2]
"Perennial with thick fleshy roots. Stem strict, ascending to erect, 1.5-5 dm tall. Leaves elliptic, 4-8.5 cm long, 1-3 cm wide, acute to obtuse, base attenuate to cuneate, sessile to short-petiolate. Flowers essentially sessile, solitary or in compact, 3-7 flowered cymes. Calyx 2-3.3 cm long, tube 7-13 mm long, lobes linear to narrowly elliptic, 10-20 mm long, to 3 mm wide, acute, erect to ascending; corolla greenish to yellowish white, usually tinted or striped with purple, funnel form, 3-4.2 cm long, tube 2.5-4 cm long, lobes 5, triangular-ovate, the corolla, anther adherent; stigmas spreading-recurved, style 3-5 mm long. Capsules ellipsoid to oblong, laterally compressed, 1.7-2.5 cm long, stipitate; seeds brown, ellipsoid to oblong, faintly reticulate, 1.1-1.3 mm long." [2]
Distribution
Gentiana villosa can be found from southeast Pennsylvania west to northern Kentucky and western Tennessee, and south to the Florida panhandle and eastern Louisiana.[1]
Ecology
Habitat
Generally, G. villosa grows in sandhill or pocosin ecotones and upland forests.[1] This species has been found in mixed woodlands, secondary, brushy pine-oak upland woods, longleaf pine-turkey oak sand ridges, and hillsides. It has been observed growing in rich, moist, humus in shaded locations.[3] It is considered a characteristic species of the shortleaf pine-oak-hickory habitat found in the Red Hills Region of northern Florida and southern Georgia.[4]
Associated species include Pinus palustris and Quercus laevis.[3]
Phenology
It generally flowers from late August until November.[5] This plant has been observed to flower from October to November.[3][6]
Seed dispersal
This species is thought to be dispersed by gravity. [7]
Fire ecology
Gentiana villosa is found in areas that are repeatedly annually burned.[3][8] It has also been found in areas that are fire-excluded.[9]
Pollination
It is considered by pollination ecologists to be of special value to bumble bees.[10]
Conservation, cultivation, and restoration
Gentiana villosa is listed as endangered by the Indiana Department of Natural Resources, by the Maryland Department of Natural Resources, by the Ohio Department of Natural Resources, and by the Pennsylvania Department of Conservation and Natural Resources.[11] It is also presumed extirpated in New Jersey and Washington D.C., and considered vulnerable in Louisiana and Alabama.[12]
Cultural use
In Appalachia, the plant has a variety of uses. It is believed carrying a piece of the plant on one's person increases physical strength. The roots are used to make a tonic tea for anxiety and digestion, and the rhizome can be a treatment for gout, indigestion, rheumatism, and nausea.[13]
