Description
"Herbs, whorled or alternate rarely opposite, entire leaves. Flowers lavender, pink, white or yellow, in racemes or spikes, terminating the branches or in terminal corymbs. Flowers perfect, zygomorphic, with 3 small sepals, frequently one of these slightly larger than the others, and 2 larger petaloid sepals (wigs). The 3 petals are united into a tube, 3-lobed at apex, the 2 lateral lobes usually the longer, the center lobe usually lacerate, often thicker in texture; stamens 6-8, united to the corolla tube in 2 rows. Capsule 2 –locular, with one seed in each locule. Seeds dark brown or black, ellipsoid or ovoid, rarely globose, 0.5-3 mm long, usually densely pubescent. The genus has been divided into several genera none of which have distinct characteristics.

Distribution
Ecology
Habitat
This species has been found in open, well-drained wiregrass-pine flatwoods and interdune swales growing on both dry and moist sands (FSU Herbarium). Observed species in sandhill longleaf pine habitat that has 1 to 3 year fire return intervals. Also seen near a cypress pond, about 1 to 2 feet from water’s edge of Pebble Hill Plantation C plots. (Michelle M. Smith – early summer 2014 and 2015).P. nana has also been found growing along the sides of highways and in the wetlands of clear cut areas (FSU Herbarium). Associated species include Pinus palustris and Aristida stricta (FSU Herbarium).
Phenology
Flowers in April (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [2]
