Basic Description: Twining perennial herbaceous vine of the pea family, with small pink-purple flowers in long clusters from the leaf axils.
Technical Description: Perennial herb; stems twining (occasionally trailing), usually climbing, 1-2 m long, pubescent; stem pubescence villosulous or loosely appressed, hairs to 0.4-0.5 mm long, or (in the "macreei" phase) strigose or strigulose, commonly retrorsely so, hairs 0.2-0.5 mm long. Leaflets ovate to oblong-lanceolate, 1.5-4.5 (-5) cm long, 1.2-4 times as long as wide, at least the lower surface spreading-hairy; inflorescence(s) usually much exserted, (2-) 4-15 (-20) cm long, bearing several to numerous flower clusters, most commonly spaced at intervals exceeding length of flower and pedicel and distributed on half or more of an elongate axis (-or axis short and few-flowered); flower buds 5-8 mm long; calyx 4-7 (-8) mm long, spreading-hairy; corolla pink-purple, fading blue, 8-12 (-14) mm long; legume 2-6 cm x 3-5 (-6) mm, strigose or puberulent with hairs 1 mm or less long. 2n = 20. Includes Fernald's (1950) G. macreei M.A. Curtis and G. volubilis var. mississippiensis Vail (with the leaflets loosely hairy on the upper as well as the lower surface). The status of populations that are commonly called G. macreei is ambiguous. These partly replace typical G. volubilis on the eastern Coastal Plain. They commonly contrast with inland G. volubilis in being loosely twining or trailing and tend to have strigulose pubescence; their leaflets are commonly narrower, their flowers are usually slightly larger, and the legumes average longer. Thus from Georgia north, the two kinds are reasonably discernible, and they may deserve the taxonomic recognition accorded by several authors. But this definition fades in peninsular Florida and on the Gulf Coastal Plain. (description mostly taken from Isely 1990, some information from Gleason & Cronquist 1991). Genus characters not mentioned above: leaves pinnately trifoliolate, well petioled; leaflets entire, stipellate, stipules inconspicuous or caducous; inflorescences axillary pseudoracemes; bracts subulate, caducous; bracteoles calycine, subulate, caducous or briefly persistent. Calyx campanulate to obconic, lobes 4, lanceolate and usually longer than tube; corolla papilionaceous, usually drying pale, commonly ephemeral; androecium diadelphous; style glabrous. Legume sessile or substipitate, dehiscent, oblong, laterally compressed. Seeds several. (Isely 1990)
Diagnostic Characteristics: Part of Isely's (1990) "G. volubilis complex" of the southeastern United States. Distinguished from other species in this complex by 1) leaves less than 5 times as long as wide (G. parviflora and G. pinetorum have leaves generally 4-12 times as long as wide); 2) twining habit (G. microphylla, G. floridana, G. smallii, and G. regularis are generally trailing plants); 3) long inflorescences, generally bearing flowers in clusters (unlike G. microphylla and G. smallii), the distance between clusters usually longer than the length of flower and pedicel (G. regularis has flowers usually closer together, at least the apical ones). In addition to these species, G. elliottii may be separated by having over 3 leaflets; G. erecta is an erect herb; G striata occurs only in southern Florida, and has the legume much wider (over 6mm wide); and G. mollis is much hairier, with bright red-purple and white flowers.
Duration: PERENNIAL
Terrestrial Habitat(s): Old field, Savanna
Habitat Comments: "Usually dry, open woodlands and borders, savannahs, old fields, thickets, roadsides; or on lower e. Coastal Plain, also marshes and beaches" (Isely 1990). G. volubilis: dry thickets & borders of woods; G. macreei: damp or wet thickets, low woods & pond-margins (Fernald 1950).
