Piriqueta caroliniana (Walter) Urban. Common name: Carolina Piriqueta. Phenology: May-Sep. Habitat: Longleaf pine sandhills, sandy soils of roadsides, woodland edges, and disturbed areas. Distribution: Se. NC and SC south to s. FL; Cuba and Hispaniola; and in Central and n. South America.

Origin/Endemic status: Native

Taxonomy Comments: Arbo (1990; 1995) treats P. caroliniana (and without infrataxa) as a subspecies of P. cistoides, but the morphological distinctions seem strong and the two taxa have widely overlapping distributions in the Neotropics. Moreover, variation in morphology and habitat seems to warrant recognition of several taxa in the southeastern United States within Arbo’s P. cistoides ssp. caroliniana. Maskas & Cruzan (2000) discuss variation and evolutionary taxa in this complex in the southeastern United States and the Bahamas. P. tomentosa, primarily of the Miami Ridge, is included here, but needs additional consideration.
