Description

"Prostrate to erect, perennial herb, stems few to many, 1-5 dm long, glabrate to bristly-hirsute. Leaves pinnately 3-foliolate; leaflets elliptic to oblanceolate, 1.5-4 cm long, entire, estipellate; stipules striate, finely pubescent to bristly hirsute, subulate, (0.4) 1-1.5 cm long, aristately tipped. Hypanthium pedicel-like, glabrous, 3-4 mm long. Calyx glabrous, tube short, campanulate above the filiform hypanthium, upper 2 lobes united, obtuse, 1.2-1.8 mm long, the 2 lateral lobes oblong, obtuse, ca. 1 mm long, the lowermost lobe acute, ca. 2 mm long; petals orange-yellow to whitish, standard 5-9 mm long; stamens 10, monadelphous, anthers alternating between oblong and subglobose. Legume short-pubescent, obliquely ovate, 3-5 mm long, sessile, reticulate, usually only the upper segment maturing, the lower pedicel-like." [1]

Distribution

Ecology

It is a legume. [2]

Habitat

Occurs in frequently burned pinelands such as longleaf pine and scrub oak ridges. [3] Also occurs in pine, oak, hickory woods. [3] Also occurs in human disturbed areas such as roadsides and right-of-ways, in clearings, fallow fields, and in pastures. [3] Associated species include Phlox floridana, Stillingia sylvatica, Asimina longiflolia var. spathulata, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceloata, Hedyotis crassifolia, Tercauloon undulatum, Asclepias humistrata, Quercus hemisphaerica, Pinus palustris, Panicum, Andropogon. [3]

It can live in xeric areas.[4] It can survive in disturbed areas.[5] In Baker County, Georgia at Jones Ecological Research Center with native groundcover managed with frequent fire.[6] [7] It is common in longleaf pine communities.[4] Hainds and his team found that S. biflora occurred in 92.3% of the plots.[8] Longleaf pine flatwoods that are mesic, fire-maintained savannas or sparse woodlands with nutrient-poor soils. [9] Longleaf pine stands that originated from seed in Rapides Parish, Louisiana that have fine sandy loam soils.[10] In Buettner Xeric Limestone Prairies in Monroe County, Illinois they have outcrops along streams and river where a prescribed burn was conducted in the nearby woody area in 2010.[11]

When exposed to soil disturbance by military training in West Georgia, S. biflora responds negatively by way of absence.[12] It also responds negatively to soil disturbance by agriculture in Southwest Georgia.[13] S. biflora does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[14]

Stylosanthes biflora is frequent and abundant in the Panhandle Xeric Sandhills and North Florida Subxeric Sandhills community types as described in Carr et al. (2010).[15]

Phenology

S. biflora has observed flowering and fruiting from April to December with peak inflorescence in May.[3][16] It has a mid-summer flowering peak.[2] Following a lightning-season burn, it continues to reproduce through late summer and fall.[2]

Seed dispersal

This species is thought to be dispersed by gravity. [17]

Fire ecology

It seems to thrive under frequent burning around the summertime. Lightning-season burns seem to significantly increase flowering, but only after a dramatic delay.[2] Density of S. biflora was greater after frequent late dormant-season fires.[18] S. biflora was found only in annual winter and annual summer long-term (20 years) burned loblolly pine plots, and even then, only rarely. [19]

Use by animals

Gopher tortoises (Gopherus polyphemus) graze on Stlosanthes bioflora.[6]
