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 was found to increase in occurrence and abundance in response to clearcutting and chopping in South Carolina. It has shown regrowth in reestablished native forest habitat that was disturbed by these practices.[7] D. laevigatum was found to be an increaser in its long-term response following cessation of repeated soil disturbance.[8]
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.[9][4]
Seed dispersal
This species is thought to be dispersed by translocation on animal fur or feathers. [10]
Fire ecology
Populations of Desmodium laevigatum have been known to persist through repeated annual burns.[11][12] 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.[13] For fire seasonality, one study found greatest abundance after a summer burn rather than a spring burn.[14]
Herbivory and toxicology
Desmodium laevigatum consists of approximately 10-25% of the diet for large mammals and terrestrial birds.[15] D. laevigatum has been recorded as a food source for white-tailed deer as well as northern bobwhite quail.[16][17]
Conservation, cultivation, and restoration
D. laevigatum is listed as endangered by the New York Department of Environmental Conservation, Division of Land and Forests.[18]
