Flora of the Southeastern United States

Isolepis cernua (Vahl) Roemer & J.A. Schultes var. cernua. Phenology: Apr-Sep. Habitat: Moist sandy soils. Distribution: Nearly worldwide in distribution (New World and Old World, and southern and northern hemispheres, but largely absent from the tropics). In North America, known from se. TX and sw. LA (Calcasieu Parish); Pacific coast of North America. The populations in TX were only relatively recently discovered (1974); it is uncertain if the species is native or introduced in the state, but given the wide distribution and weedy nature of the species, it is plausible that these populations are native but previously overlooked.

Origin/Endemic status: W. North America
