Cuphea carthagenensis (Jacquin) J.F. Macbride, Lythraceae: a newly naturalised species from eastern Nepal

Abstract

Cuphea carthagenensis (Jacquin) J.F. Macbride, a native of South America, is recorded for the first time from Mechinagar municipality of south‑eastern Nepal. This weed has already been in the neighboring north‑east region of India since the 1950s and might have recently spread into south‑eastern Nepal where it is colonizing riparian habitats. We provide a detailed taxonomic account, as well as the distribution, major habitat, and invasion status of C. carthagenensis.
