Brittonia Aims and scope Submit manuscript

Abstract

During herbarium studies for the Flora of Cuba, a new species was found, Parapolystichum villosissimum, which is here described. The species is endemic to Cuba and known from only four collections from the mountain ranges of southeastern Cuba. The last specimen collected was made over 90 years ago. Recent efforts to relocate this species were unsuccessful, suggesting that it should be treated as threatened. The new species is described, illustrated, and compared to the most similar species. A key to the Neotropical species of Parapolystichum is also provided.

Resumen

Durante estudios de herbario para la Flora de Cuba, una nueva especie fue encontrada, Parapolystichum villosissimum, la cual se describe aquí. La especie es endémica de Cuba, con solo cuatro colecciones conocidas de las cordilleras del sudeste de Cuba. El último espécimen fue recolectado hace más de 90 años. Esfuerzos recientes para reubicar esta especie no tuvieron éxito, lo que sugiere que está amenazada. La nueva especie se describe, ilustra y compara con las especies similares. También se presenta una clave para las especies neotropicales de Parapolystichum.
