Alloneuron trinervium (Melastomataceae: Cyphostyleae), a new species from Colombia

Abstract

Alloneuron trinervium, a new species of Melastomataceae known only from the type locality in Antioquia Department, northwestern Colombia, is described and illustrated. This new species is the only one in Alloneuron with three basal veins, a venation pattern that is intermediate between semi-craspedodromous (found in all other members of the genus) and acrodromous (predominant in the rest of the family). Alloneurum trinervium is further distinguished by the paniculate inflorescences with 4-merous, pedicellate flowers arranged in monochasial cymes bearing 3(−5) flowers along the filiform paracladia. This is the first species in the genus found in an inter-Andean valley and not in the eastern slope of the Andes.
