Description

Generally for the Desmodium genus, they are "annual or perennial herbs, shrubs or small trees. Leaves 1-5 foliolate, pinnately 3-foliolate in ours or rarely the uppermost or lowermost 1-foliolate; leaflets entire, usually stipellate; stipules caduceus to persistent, ovate to subulate, foliaceous to setaceous, often striate. Inflorescence terminal and from the upper axils, paniculate or occasionally racemose; pedicel of each papilionaceous flower subtended by a secondary bract or bractlet, the cluster of 1-few flowers subtended by a primary bract. Calyx slightly to conspicuously 2-lipped, the upper lip scarcely bifid, the lower lip 3-dentate; petals pink, roseate, purple, bluish or white; stamens monadelphous or more commonly diadelphous and then 9 and 1. Legume a stipitate loment, the segments 2-many or rarely solitary, usually flattened and densely uncinated-pubescent, separating into 1-seeded, indehiscent segments." [1].

Specifically, for D. laevigatum species, they are "erect perennial; stems 0.5-1.2 m tall, glabrous to sparsely and inconspicuously uncinulate-puberulent. Terminal leaflets ovate to elliptic-ovate or elliptic-oblong, (3) 4-7 (9) cm long, glabrous to very sparsely puberulent above, glabrous to puberulent or sparsely short-pilose, often glaucous beneath with the trichomes largely restricted to the principal veins; stipules caduceus, lance-attenuate, 5-8 mm long; stipels persistent. Inflorescence usually paniculate, moderately to densely uncinulate-puberulent; pedicels mostly 7-19 mm long. Calyx densely puberulent; petals pink or roseate to purple, 8-10 mm long; stamens diadelphous. Loment of 2-5 subrhombic segments, each about 5-8 mm long, 3.5-5 mm broad, with a straight or slightly convex upper suture and an abruptly angled lower suture, with densely uncinulate sutures; stipe ca. 4.5-6.5 mm longer, much longer than the calyx tube but often equaling or even exceeding the calyx lobes, shorter than stamina remnants." [1].

Distribution

Ecology

Habitat

It is found in areas that frequently burn such as open woods bordering a bay, hardwood hammocks, upland pine, in open mixed pine-hardwood forest, well drained upland, savannas, turkey oak sand ridges. Requires low-high light levels. Is associated with loamy sand, sandy clay loam, limestone, and sand soil types[2].

Associated species include Desmodium ciliare, D. lineatum, D. glabellum[2].

Phenology

It has been observed flowering and fruiting from September to November[2].
