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. Orange flowers turn pale yellow on drying, yellow ones bluish green; the pink or lavender ones remain the same color or fade slightly." [1]
"Similar to P. lutea. 3-15 cm tall, with leaves mostly confined to a basal rosette; stem leaves few. Flowers lemon yellow. Wings 7-8 mm long, long acuminate." [1]
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. [2] 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. [2] Associated species include Pinus palustris and Aristida stricta. [2]
Phenology
Flowers from January to July with peak inflorescence in April.[2][3]
Seed dispersal
This species disperses by explosion mechanisms or by ants. [4]
