First record of Neea madeirana (Nyctaginaceae: Pisonieae) from the Peruvian Amazon

Abstract

Neea is one of the largest genera of Nyctaginaceae and comprises approximately 80 species distributed in the Neotropical region. Here, we report for the first time the occurrence of Neea madeirana in Peru, almost 50 years after it was first collected in this country, but was misidentified as Guapira noxia. We also insert N. madeirana in the identification key for Peruvian species of Neea and update the distribution map of N. madeirana. Given that we have not located any posterior specimen of G. noxia in Peruvian collections, and the original specimens cited as G. noxia correspond to N. madeirana, we suggest the exclusion of G. noxia from the Peruvian flora checklist.
