Taxonomic notes

Varieties: none[1]

Description

Generally, for 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. marilandicum species, they are "erect perennial; stems 0.6-1.5 m tall, glabrous or sparsely uncinulate-puberulent and short-pubescent, but never pilose. Terminal leaflets ovate to suborbicular or oblong to elliptic, 1-2.5 (5) cm long, usually 1.6-2.2 as long as wide, both surfaces glabrous to moderately short-pubescent especially on the calyx lobes; petals purplish, 4-6 mm long; stamens diadelphous. Loment of 1-3 weekly obovate segments, each 3.5-5.5 mm long, 3-4 mm broad, slightly convex to almost straight along the upper suture; stipe 1.5-2.5 mm long, equaling or shorter than the calyx and exceeded by the stamina remnants." [2]

Distribution

D. marilandicum is native to the United States from Massachusetts west to Michigan and Missouri and south to Texas and north peninsular Florida.[3] It is also native to Ontario province in Canada.[4]

Ecology

Habitat

Generally, D. marilandicum can be found in woodland borders, fields, and disturbed areas.[3] Habitats that D. marilandicum has been observed in include pine-oak-hickory woodlands, open, upland pine, dry ridges, and sandhills. Can occur in disturbed areas such as woodlands bordering the road, clearing in a live-oak woodland, clearing between pineland and field, edge of mixed woods around a campground, sterile hillside, and abandoned fields. Requires semi-shaded to open areas. A study exploring longleaf pine patch dynamics found D. marilandicum to be most strongly represented within stands of longleaf pine that are between 130-180 years of age.[5]

D. marilandicum grows in loamy sand and clayey soil types.[6] D. marilandicum was found to increase in occurrence in response to soil disturbance by agriculture in South Carolina coastal plain habitat. It has shown regrowth in reestablished longleaf pineland that was disturbed by agriculture, making it a post-agricultural woodlands indicator species.[7][8][9] Additionally, it was found to have variable changes in occurrence and abundance to disturbance by clearcutting and chopping in South Carolina. It showed both resistance to regrowth and positive regrowth in areas with reestablished native forest habitat that was disturbed by these practices.[10] D. marilandicum was found to be neutral in its long-term response following cessation of repeated soil disturbance.[11]

Associated species: Desmodium strictumm, Pinus palustris, Aristida sp., and others.[6]

Phenology

D. marilandicum flowers from June to September, and fruits from June to September.[3] It has been observed flowering from August through October with peak inflorescence in October; and fruiting from September through November.[6][12] The fruit is dry but does not split open when ripe.[13]

Seed dispersal

This species is thought to be dispersed by translocation on animal fur or feathers. [14]

Fire ecology

Populations of Desmodium marilandicum have been known to persist through repeated annual burns,[15][16] and withstand areas with winter burns.[6] Fire seasonality does not seem to affect D. marilandicum much since one study found the species in high frequency after spring and summer burns as well.[17] A study by Lajeunesse in 2006 found that nitrogen and carbon levels significantly increased in D. marilandicum populations in both sandy and clayey sites, where more of a difference was seen in sandy than clayey sites.[18]

Pollination

A short tongued bee Calliopsis andreniformis has been observed on Desmodium marilandicum.[19]

Herbivory and toxicology

D. marilandicum is a source of food for white-tailed deer.[20]

Conservation, cultivation, and restoration

D. marilandicum is listed as endangered by the New Hampshire Natural Heritage Inventory, Division of Forests and Lands.[4] For restoration, D. marilandicum can be planted along with other native forb species to restore longleaf pine-wiregrass savanna herbaceous vegetation.[21]
