Synonym: Meibomia laevigata (Nuttall) Kuntze.[1]
Varieties: none.[1]
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." [2]
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." [2]
Distribution
D. laevigatum is native to the United States from south New York west to Indiana and Missouri, south to north Florida and the panhandle, and west to Texas.[3]
Ecology
Habitat
This species is commonly found in fields, woodland borders, pine and dry oak forests, and disturbed areas in its native distribution.[3] It has been observed 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.[4] Where it is found, it is infrequent compared to other Desmodium species that can be found in the same habitat.[5] D. laevigatum has been found to respond positively to disturbance, where a study found flowering to increase in response to tornado damage and in turn an increase in light.[6] D. laevigatum responds positively to clearcutting and chopping in South Carolina.[7]
Associated species include Desmodium ciliare, D. lineatum, D. glabellum.[4]
Phenology
D. laevigatum commonly flowers between June and September and fruits between August and October.[3] It has been observed flowering from September to November with peak inflorescence in September; it is also been observed fruiting during the same time period.[8][4]
Seed dispersal
This species is thought to be dispersed by translocation on animal fur or feathers. [9]
Fire ecology
It has been observed in areas that are frequently burned[4], but has also been found in areas that are fire excluded which means it is not fully fire dependent.[10] For fire seasonality, one study found greatest abundance after a summer burn rather than a spring burn.[11]
Use by animals
It consists of approximately 10-25% of the diet for large mammals and terrestrial birds.[12] D. laevigatum has been recorded as a food source for white-tailed deer as well as northern bobwhite quail.[13][14]
Conservation and management
D. laevigatum is listed as endangered by the New York Department of Environmental Conservation, Division of Land and Forests.[15]
