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." - Radford et al 1964

"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." - Radford et al 1964
