Taxonomic Notes

Synonym: Hedysarum repens[2]

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.[4] Hybridization of L. repens and L. hirta has been reported in Missouri.[5]

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 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.[6] 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.[7]

Phenology

In the southeastern and mid-Atlantic United States flowering occurs from July through September and fruiting occurs from August through November.[1]

Seed dispersal

This species is thought to be dispersed by translocation on animal fur or feathers. [8]

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.[9]

Use by animals

L. repens composes 2-5% of the diet of some large mammals and 10-25% of some terrestrial birds.[10] 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.[11]
