Palafoxia reverchonii, commonly known as Reverchon's palafoxia, is a species of flowering plant in the family Asteraceae. It is endemic to the Texas Coastal Plain, where it inhabits sandy, fire-influenced woodlands.[1]

Description

Palafoxia reverchonii is an herbaceous plant that grows in dry, sandy habitats. Like other members of the genus Palafoxia, it produces composite flower heads typical of the family Asteraceae, with involucral bracts and ray-like florets adapted for insect pollination.[1]

Distribution and habitat

This species is restricted to the Texas Coastal Plain and is endemic to the state.[1][2]

It occurs in longleaf pine woodlands and other dry, sandy oak–pine woodlands, habitats typically maintained by periodic fire and characterized by well-drained soils.[1]

Phenology

Flowering occurs from September through October.[1]

Taxonomy

The species was originally described as Othake reverchonii by Bush in 1904.[3] It was later transferred to the genus Palafoxia by James S. Cory in 1946.[3]

Additional taxonomic treatments have placed the species in the genus Polypteris.[4]

The type material was collected by J. Reverchon in Texas in the early 20th century, with specimens preserved in several major herbaria.[4]

Conservation

Palafoxia reverchonii is ranked as G4 (apparently secure) globally by NatureServe, though the status has not been recently reviewed.[2]

Within the United States it is ranked N4, and in Texas it is considered S4 (apparently secure).[2] Despite this, the species is restricted to a single-state range and is associated with fire-maintained sandy habitats, which may be impacted by land-use change and fire suppression.[1]
