Richardia scabra, commonly called rough Mexican clover[1] or Florida pusley, is a species of flowering plant in the family Rubiaceae. It is widespread, native to warm areas of both North America, South America and East African countries like in Central Kenya .
The stems of R. scabra may reach a height between 1 and 7 decimeters (4 to 27.5 inches). The leaves are oppositely arranged, and lanceolate to elliptic in shape. They range in size from 2.5 to 7 centimeters (1 to 2.75 inches) in length.[2] Individuals produce white flowers, inflorescence beginning as early as March and may last through December.[2][3] The fruit produced by R. scabra is leathery in texture and is 3 to 4 millimeters in length.[2]
Habitat
In the southeastern United States, this species is often found in disturbed habitats, with individuals observed in habitats such as along roadsides and within vacant lots.[4][5]
Within the United States' Coastal Plain region, R. scabra occurs within environments that possess fine sandy loams with slow permeability.[6] Individuals have been documented in habitats such as upland pine communities and woodlands.[5]
