Description:Species Description - Climbing, or trailing, this hairy vine, with broad leaflets and small, yellow flowers, inhabits dry and moist parts of Porto Rico, at lower and middle altitudes, and also the small islands Mona, Vieques and Culebra. It grows nearly throughout the West Indies, and on the continent from southern Mexico to Costa Rica and Colombia. Besides the species here illustrated, there are 2 others in the Porto Rico Flora.
Dolicholus(diminutive of Dolichos, a related genus) established by the German botanist Medicus in 1787, is a large genus, including about 200 species, of tropical and temperate regions. They are perennial vines, or erect herbs, their leaves with 3 leaflets, or in some species only 1, and small, yellow, clustered, mostly axillary flowers. The 4-lobed, or 5-lobed calyx is somewhat 2-lipped ; the standard petal is broad, spreading, or reflexed, the wing-petals narrow, the keel more or less curved; there are 10 stamens, of which 9 are united by their filaments; the nearly stalkless ovary contains only 1 or 2 ovules, and the style is slender. The flat, oblong to nearly orbicular, more or less oblique pod splits elastically into two valves, releasing the 1 or 2 seeds.
Dolicholus reticulatus (netted-veined leaflets) may reach a length of about 5 meters. Its stalked leaves have 3, elliptic or ovate, netted-veined, pointed, or blunt leaflets from 5 to 10 centimeters long, the 2 lateral ones nearly stalkless, the end one long-stalked. The flower-clusters are shorter than the leaves, the individual flowers on very short stalks; the deeply 4-cleft calyx is from 7 to 12 millimeters long, with lance-shaped, pointed lobes; the s tandard petal is a little longer than the calyx. The pod is lunate in form, about 2.5 centimeters long, from 6 to 9 millimeters wide, the seeds small and nearly black.
