Varieties: none.[4]

Description

Lespedeza repens is a dioecious perennial forb/herb.[2] Its stems and peduncles are sparsely short-appressed-pubescent. Stems can grow to 1 m in length. Racemes typically contain 4-8 flowers that are 5-7 mm long. Leaves gradually get smaller towards the stem tips. Terminal leaflets are membranous, elliptic to obovate, glabrous, and can reach 2.5 cm in length.[5] Hybridization of L. repens and L. hirta has been reported in Missouri.[6]

Distribution

This species occurs from Connecticut and New York, westward to northern Ohio, southern Wisconsin, Missouri, and Kansas, and southward to northern peninsular Florida, panhandle Florida, and central Texas.[1]

Ecology

Habitat

L. repens is found in turkey oak sand ridges, dry longleaf pine sandhills, wire grass sand ridges, clay fields, pine flatwoods, and areas with loamy sands.[7] It is also found in disturbed areas including burned longleaf pine forests, along roadsides, fallow fields, vacant lots, and burned saw palmetto-slash pine woodland.[7] Associated species: Tephrosia, Psoralea, Scleria, and Rhynchospora.[7] Lespedeza repens is an indicator species for the Clayhill Longleaf Woodlands and Panhandle Silty Longleaf Woodlands community types as described in Carr et al. (2010).[8] L. repens is occurs in woodlands and woodland borders.[1] In a North Carolina woodland, L. repens was found with 0.8 stems m-2, a frequency of 0.188, and percent cover of 0.10.[9] In Florida clayhill longleaf woodlands, L. repens was reported with a relative frequency of 93 and coverage of 0.38. Panhandle silty longleaf woodlands had frequencies of 82 and coverage of 0.27.[10]

L. repens was found to decrease its occurrence in response to soil disturbance by agriculture in South Carolina and southwest Georgia.[11][12] It has shown resistance to regrowth in reestablished pine woodlands that were disturbed by agriculture, making it a remnant woodland indicator species.[11] However, it was found to increase its occurrence and abundance in response to soil disturbance by clearcutting and chopping in South Carolina. It has shown regrowth in reestablished native habitats that were disturbed by these practices.[13]

Phenology

L. repens has been observed to flower from April to October[14], with peak inflorescence in April. Fruiting has been observed from August to November.[1]

Seed dispersal

This species is thought to be dispersed by translocation on animal fur or feathers.[15]

Fire ecology

L. repens may require fire to maintain higher frequencies. On the Florida panhandle sandhills, its frequency was 25 in 1966. After 57 years of not burning, the frequency dropped to 4.[16]

Populations of Lespedeza repens have been known to persist through repeated annual burns.[17][18]

Pollination and use by animals

L. repens has been observed to host ground-nesting bees such as Calliopsis andreniformis (family Andrenidae), sweat bees such as Nomia maneei (family Halictidae), and leafcutting bees from the Megachilidae family such as Megachile brevis, M. exilis, and M. mendica.[19] L. repens composes 2-5% of the diet of some large mammals and 10-25% of some terrestrial birds.[20] During a study in central Texas, L. repens was the most preferred forage in 1996 and third preferred in 1997 by white-tailed deer. The study also showed L. repens is 16.9% crude protien and 78.4% condensed tannin.[21]
