Inflorescence a terminal bracteate raceme; pedicels equaling or shorter than the peduncles. Calyx 5 parted, 5-8 mm long; petals 5, brilliant orange-yellow, 1.5-2 cm long; stamens 5, shorter than the petals; pistil 3- parted, stigmas brush-like capsule 3-valved, 1-celled, globose, 5-7 mm long.

Distribution
Ecology
Habitat
Natural habitats include open upland pine woodland; well drained longleaf pineland; scattered on slopes and ridges in a longleaf pine forest; recently burned sandhill; and longleaf, wiregrass habitat (FSU Herbarium). It has also been documented to occur along powerline corridors. It has been observed to grow in drying loamy sand (FSU Herbarium). Associated species include longleaf pine and wiregrass (FSU Herbarium).
Phenology
P. cistoides has been observed to bloom in August (FSU Herbarium). Kevin Robertson has observed this species flower within three months of burning. KMR
