Carlowrightia henricksonii T.F. Daniel

PHENOLOGY.— Flowering: April–September; fruiting: April–September.

DISTRIBUTION.— Mexico (Tamps.).

HABITAT.— Sandy prairies, sometimes on limestone.

ELEVATION.— 160–175 meters.

NOTES.— Daniel (1983a) provided a description of this rare species, which is endemic to Tamaulipas. The species is known from only three collections. The whereabouts of Wooton’s collection locality has not been determined, and thus an EOO cannot be determined. Depending on the location of Wooton’s collection, an AOO of either 8 or 12 km 2 is likely for the species. A potential conservation assessment of either critically endangered (CR) or endangered (EN) would be likely if threats and their impacts to the species were to be identified ( IUCN 2019).
