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. lineatum species, they are "perennial with uncinate-pubescent to glabrate, trailing stems, 5-7 dm long. Terminal leaflets ovate, rhombic, ovate or elliptic to orbicular, 0.7-3 cm long, 5-7 dm long. Terminal leaflets ovate, rhombic, obovate or elliptic to orbicular, 0.7-3 cm long, usually about ¾ as wide as long, finely reticulate, both surfaces glabrous or nearly so to densely uncinulate-puberulent and short-pubescent; stipules lance-attenuate to linear-subulate, striate, 2-5 mm long; stipels persistent. Inflorescence paniculate, usually densely uncinulate-puberulent and more sparsely uncinulate-pubescent; pedicels 0.6-1.6 cm long. Calyx densely puberulent and also sparsely short-pubescent; petals purplish, 4-6 mm long; stamens diadelphous. Loment usually of 2-3 segments, each 3.5-6 mm long, 2.5-3.5 mm broad, straight to somewhat curved along the upper suture while broadly rounded below, both sides and sutures very densely uncinulate; stipe longer than calyx tube, about equaling the longest calyx lobe, shorter than the stamina remnants." [2]
Distribution
Found in Alabama, Georgia, Florida, and South Carolina. [3] It is primarily found in the panhandle and upper peninsular of Florida. [4] It is rarely found inland.[1]
Ecology
Habitat
D. lineatum is commonly found in sandhills as well as other dry woodlands and forests.[1] It is found in frequently burned upland longleaf and shortleaf pine native and old-field communities (Ultisols),[5][6] pine-oak sandhills (Entisols), pine flatwoods (Spodosols), and open areas within upland hardwood forests. Thrives in frequently burned (1-2 year fire interval) areas (Gilliam et al 2009).[6] D. lineatum is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[7] A study exploring longleaf pine patch dynamics found D. lineatum to be most strongly represented within stands of longleaf pine that are between 90-130 years of age.[8]
D. lineatum occurs primarily on sandy soils but can occur on a wide range of soils including sandy loam and sandy clay. It occurs in both full sun and partially shade,[6] but having a prostrate habit it is not tolerant of very dense groundcover vegetation.[9] It is occurs in both native communities and in areas with a history of soil disturbance[6]. As well, it is a characteristic species of the clayhill longleaf woodlands habitat in Florida.[10] D. lineatum was found to have increased occurrence in response to soil disturbance by agriculture in South Carolina. It has shown regrowth in reestablished native longleaf pineland habitat that was disturbed by agriculture, making it a post-agricultural woodland indicator species.[11][12] Additionaly, it was found to be an increaser in its long-term response following cessation of repeated soil disturbance.[13]
Associated species include Desmodium ciliare, D. floridanum, D. ochroleucum, D. rotundifolium, D. laevigatum, Quercus laevis, Pinus elliotti.[6]
Phenology
D. lineatum commonly flowers between June and September and fruits between August and October.[14] However, it has been observed flowering and fruiting April through November (primarily in autumn).[6] Another source has observed D. lineatum to be flowering between April and June as well as between September and November with peak inflorescence in September and October.[15]
Seed dispersal
Seeds of this species are thought to be dispersed by translocation on animal fur or feathers. [16] The hooked hairs on the loments (legume pods) readily attach to fur as well as clothes.[9]
Fire ecology
Populations of Desmodium lineatum have been known to persist through repeated annual burns.[17][18] It is associated with frequently burned areas such as pinelands, pine flatwoods, savannas, and mature Longleaf pine-wiregrass uplands.[6] However, it has also been found in fire excluded habitats, which show that D. lineatum is not fully fire dependent.[19] Hiers et al. (2000) found that flower production was significantly higher in burned areas compared to unburned areas. However, season of burn did not greatly influence flower production, duration of bloom, or timing of peak synchrony.[20] It benefits most from high fire return intervals.[21]
Diseases and parasites
The species can be infected by root-knot nematodes, including Meloidogyne arenaria, M. incognita, and M. javanica.[22]
Conservation, cultivation, and restoration
This species is listed as endangered by the Maryland Department of Natural Resources, Natural Heritage Program.[23]
