| Distribution | The only annotated specimens are at herbaria DUKE and NCU, collected in 1885 from "eastern North Carolina" by G. McCarthy. Other specimens included in B. diffusa by SERNEC are actually B. coccinea.
Native of the pantropics; in N.A. NC to FL and perhaps native in southern FL. Weakley (2018) shows it as native north to the SC Coastal Plain. Weakley's (2022) map now shows NC within the native range. However, this is possibly a moot point now. | |
| Abundance | Very rare. Not seen since 1885 and perhaps a one-time waif. | |
| Habitat | No data for NC records. Generally in various disturbed areas. | |
| Phenology | Flowering and fruiting not reported. | |
| Identification | Red Spiderling has much larger leaf blades than the other 2 species in NC, and they are broadly elliptical to rotund. The flowers are mostly pink to purple, in a dense ball. | |
