Tephrosia hispidula, also known as sprawling hoarypea, is a species of perennial legume native to North America.[1]

Description

The stems of T. hispidula range from decumbent to erect in stature, reaching a length of up to 50 cm (20 in).[2] The leaves are narrowly elliptic to elliptic-lanceolate in shape, with bicolored blades ranging in length from 9 to 20 cm (3.5 to 7.9 in).[3] They are glabrous to densely pubescent on the top and sparsely to densely pubescent on the underside.[2]

Inflorescence occurs opposite the leaves, ranging from 5 to 15 cm (2.0 to 5.9 in) in length, with a flattened peduncle or terete and narrowly lanceolate to linear bracts.[2] The corolla starts as white to yellow in coloration, transitioning over time to reddish.[3]

When legumes are produced they are 3 to 4.2 cm (1.2 to 1.7 in) in length and sparsely to moderately pubescent, with trichomes at least 0.6 mm (0.024 in) in length.[2]

Distribution and habitat

Tephrosia hispidula is endemic to the southeastern region of the United States, its range stretching from Virginia south to Florida and westward to Louisiana.[1] It may be found in environments such as pine savannas, sandhills, hardwood swamps, wiregrass woodlands, and alongside rivers.[4][5]
