C. virginianum habitats are in pine lands and coastal uplands.[2]

Morphology[edit]

Centrosema virginianum are perennial and herbaceous vine [3] a couple meters in length; stems are approximately 29 to 160 centimeters long.[1] It has three alternate pinnately leaves, 3 to 10 centimeters long. C. virginianum stipules are lanceolate or ovate, 1 to 4 mm long,[1] and the petiole are identify to be 2 to 5 cm long. C. virginianum is often deciduous, however it is mostly setaceous.[1] There is a wide range of leaflets from linear to ovate to oblong or lanceolate-oblong, acute or acuminate at the apex.[1] C. virginianum produces abundant flowers, between early August and late September [3]
