| Distribution | FNA and BONAP map it for NC, but without location. Weakley (2018) maps it in the Coastal Plain. There are no specimens at SERNEC. RAB (1968) cites only a single record from a railroad yard in Charleston County, SC.
Native of the Neotropics, and apparently also north to the U.S. Southwest. Adventive east of the Mississippi River (the boundary between native and non-native is obscure). | |
| Abundance | Very rare. A specimen voucher is highly desirable! | |
| Habitat | No data for NC; various disturbed habitats. | |
| Phenology | Flowering and fruiting July-November. | |
| Identification | This species is an annual -- glabrous, succulent, prostrate, and diffusely branched. The leaves are sub-opposite, stalked, and elliptical, one of the pair larger than the other (a very odd and rarely seen character). The flowers are usually single in the axils, the sepals purplish, petals absent. | |
