Description
"Glabrous, perennial or annual herbs with erect or ascending stems. Leaves opposite, entire, sessile. Inflorescence terminal, cymose. Calyx 5-13 parted, lobes united at bae, those of first flowers longest, smaller on later flowers; corolla rotate white or pink with yellow eye, lobes 5-13, tube becoming membranous and persistent around the capsule. Capsule ovoid to ellipsoid; seeds small, alveolate." - Radford et al 1964
"Annual, rhizomes absent. Stems freely branched, terete or slightly angled above, 2-5 dm tall. Basal leaves present or absent at anthesis; stems leaves linear to narrowly lanceolate or elliptic-oblanceolate, 1-2.5 cm long, 1-8 mm wide, acute to obtuse. Inflorescence paniculate, branches alternate, to 3 dm long, 0.5-2.5 dm broad. Calyx lobes 5, linear, 2-7 mm long; corolla lobes white, usually white on drying, elliptic to oblanceolate, 1-1.5 cm long, 2-4 mm wide; filaments 1-2 mm long; stigmas 3-4 mm long, style 0-1 mm long. Capsule 4-5 mm long; seeds brown, 0.3-0.4 mm long." - Radford et al 1964
Distribution
Regionally endemic to the Coastal Plain from Virginia south through most of Florida and west to southern Alabama. It is rare in Alabama[1].
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. brevifolia can occur in wet pine flatwoods, moist sand around ephemeral ponds in open flatwoods[2], seepage bogs on pineland slopes, borders of cypress-gum ponds, exposed shores of sinkhole ponds, and sometimes open well-drained woodlands[1]. Associated species Polygala cruciata, P. hookeri, P. lutea, Eupatorium leucolepis[2].
Phenology
White flowers bloom August through November[3].
Seed dispersal
