A potential invasive species in Cuba (Angiopteris evecta): updated morphological description and distribution

Abstract

Angiopteris evecta is a fern species of the family Marattiaceae. It is native to the South Pacific, but it has been introduced into other localities since the 18^th century and is currently listed as an invasive species in several regions (Costa Rica, Jamaica and Hawaii). In Cuba, it has been recorded in the eastern part of the archipelago. Due to the invasive behavior of this species, we intended to update the description and distribution of A. evecta in the country. The distribution and morphological data are based on two herbarium specimens from HAJB, from which the stem and leaf characters were measured. We confirmed that the species can be identified by the following features: 2-pinnate leaves; its lanceolate, narrow and herbaceous pinnules, with a crenate margin and lateral false veinlets. The species occurs in Gran Piedra (Santiago de Cuba) and in the proximity of Yunque de Baracoa (Guantanamo), in the montane rainforest, at an altitude of 250-600 m a.s.l. It is necessary to emphasize its inclusion in the management strategies for the localities where it has been detected, in order to prevent its future spread.
