Description
In Radford (1964) this species was recognized as a synonym under Bonamia humistrata which is where this description originated from. "Prostrate or spreading, herbaceous perennial vines, from fascicled or single, slender linear roots. Stems several to many, 0.5-2 m long, the basal portions appearing rhizomatous, older plants often forming large mats or clumps. Leaves entire. Corolla white or pink, campanulate to funnelform, 8-24 mm long; sepals still or leathery, 5-10 mm long, obtuse or acute; stigmas globose or peltate, styles 2, united at base or almost to summit. Capsule chartaceous, 2-locular, 4-seeded, 4-8 mm long, ½ as wide." [1]
"Leaves elliptic to elliptic-lanceolate, 2.5-5 cm long, 1.2-2.8 cm wide, reduced, upward, mucronate, subcordate, sparsely pubescent to pilose, the trichomes stellate or simple. Flowers 1-3 (rarely more) on peduncles normally 1-2X the length of the subtending leaf, bractlets inconspicuous; sepals glabrous; corolla white, usually 15-20 mm long; filaments pubescent to pilose; basal third or less of styles united." [1]
Distribution
It is found in the Coastal Plains of southwestern Georgia (Baker County). [2]
Ecology
Habitat
Stylisma humistrata can be found in longleaf pine-oak woodlands, longleaf pine-wiregrass-scrub oak ridges, annually burned pinelands, mesic woodlands, floodplains, hardwood hammocks, [3] and subxeric and xeric areas in longleaf pine-oak communities.[4] It can also be found along roadsides, edges of cornfields, recently logged oak-pine slopes, and old fields. [3] Soil types include loamy sand, loam, and red sandy clay. [3] Associated species include Spigelia gentianoides and Quercus incana. [3]
Phenology
Flowers and fruits May through October. [3]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [5]
Seed bank and germination
S. humistrata exhibits physical seed dormancy and does not require light for germination. [6]
