Description
Houstonia procumbens is a perennial herbaceous species with a procumbent, spreading growth habit and small white flowers (FSU Herbarium).
"Erect or creeping annuals or perennials. Leaves opposite, the bases connected by small stipules. Flowers in cymes or appearing solitary; sepals 4, lanceolate or subulate; corolla salverform or funnelform, lobes usually shorter than the tube; stamens 4, included. Capsule 2-locular, slightly flattened, the lower ½ enclosed by the calyx tube, the apex loculicidal." - Radford et al 1964
"Prostrate or weakly decumbent, creeping perennial, the solitary pedicels erect, 1-4 cm tall. Leaves widely ovate to suborbicular, 7-10 mm long, 4-10 mm wide, margins ciliolate. Corolla white, the tube 5-7 mm long, glabrous within, lobes 4-6 mm long. Capsule 3-4 mm broad." - Radford et al 1964

Ecology
Habitat
H. procumbens occurs in moist to dry sandy or loamy soils, or in loose sand[1]. It can be found in light conditions from partial shade to full sun. Native habitat it can be found in includes longleaf pine-scrub oak-wiregrass sand ridges, mixed hardwood woodlands, open slash pine stands, sand dunes, turkey oak scrub, and on stream banks. However, it can also occur in disturbed habitat such as roadsides, parking areas, cutover pinewoods, mowed lawns, bulldozed slash pine savannas, open pastures, and along trails. Associated species include Pinus palustris, Quercus, Aristida stricta, Pinus elliottii, Quercus virginiana, Phlox floridana, Stillingia sylvatica, Asimina longifolia var. spathulata, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocaulon undulatum, Asclepias humistrata, and Quercus hemisphaerica[1].
Phenology
This species has been observed flowering in January through May, July, and October (FSU Herbarium). Fruiting has been observed in February through May, October, and November (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [2]
Fire ecology
This species has been found in habitat that is often maintained by occasional fire (FSU Herbarium).
