Description
"Perennial herb, 1.5-5 dm tall, forming colonies by root sprouts, stem pubescence densely stellate, admixed with long, spreading trichomes. Leaves alternate, oblong to lanceolate, 2.5-5 cm long, 0.5 -1.7 cm wide, finely stellate pubescent on both surfaces with long trichomes on the midrib below, obtuse, rarely acute, base rounded to attenuate, sessile or petioles to 2 mm long. 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. Seeds tan or blackish gray, obovate, 1.8-2 mm long, ribbed, arillate."[2]
Distribution
P. cistoides was reported for Georgia, but the documentation is untraceable. A better confirmation is pending.[1]
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.[3] It has also been documented to occur along powerline corridors. It has been observed to grow in drying loamy sand.[3] Associated species include longleaf pine and wiregrass.[3]
Phenology
P. cistoides has been observed to flower from April through September, with peak inflorescence in May.[3][4] Kevin Robertson has observed this species flower within three months of burning. KMR
Seed dispersal
This species is thought to be dispersed by ants and/or explosive dehiscence.[5] P. cistoides seeds were observed to be readily retrieved by fire ants in a 2013 study on seed dispersal by the imported fire ant species in the southeast.[6]
Fire ecology
Populations of Piriqueta cistoides have been known to persist through repeated annual burns.[7]
Pollination
Piriqueta cistoides has been observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Augochlorella aurata, Augochloropsis metallica, and Lasioglossum nymphalis.[8]
Herbivory and toxicology
The gulf fritillary (Agraulis vanillae) uses P. cistoides. subsp. caroliniana as a host plant. Native bees feed from the flowers and ants feed off the elaiosome from the P. cistoides. subsp. caroliniana.[9]
