RESUMEN

A partir de la revisión taxonómica de exsicatas depositadas en herbarios nacionales y extranjeros, se exponen los aportes al conocimiento taxonómico del género Persea (Lauraceae) en Venezuela. Se reportan 24 especies, incluyendo una especie y dos variedades nuevas para la ciencia, nuevos reportes para el país, ampliaciones de distribución, mapas de distribución y una clave actualizada para la determinación de especies en Venezuela. Utilizando el paquete DELTA, se obtuvieron descripciones en lenguaje natural y una clave interactiva para la identificación de taxones.

ABSTRACT

A taxonomical revision was carried out for species of Persea (Lauraceae) in Venezuela from vouchers deposited at Venezuelan and foreign herbaria. Twenty-four species, including one new species and two new varities, new registers to Venezuela, expansion of distribution, distribution maps, and updated key for species at north and south of Orinoco River are reported.
