Cuticular features potentially offer valuable information on phytotaxonomy, especially for plants that are difficult to classify or identify. Cryptocarya is one such difficult and poorly known genus, and we investigated its cuticular features to evaluate their taxonomic implications. We examined cutinized leaf epidermis and the stomatal complex for 21 species from Peninsular Malaysia, Thailand and Indo-China, as well as one species endemic to Borneo and one to Sumatra, and compared features among members of this group, between this group and congeners in the other countries, and between this group and the other genera of Lauraceae. Many of the Cryptocarya species studied have straight to slightly curved anticlinal epidermal walls and butterfly-shaped stomatal ledges, although some variation was seen in the ornamentation of the periclinal epidermal walls and the appearance of the stomatal complex. Based on these results, we recognized four groups and two subgroups among the South-east Asian species. Comparison with congeneric taxa in the other countries indicates that butterfly-shaped stomatal ledges are often shared among the species across the regions. However, no cuticular features occur exclusively in any of the species groups of Cryptocarya studied here, nor in the genus as a whole. We consider that cuticular features are useful in the recognition of infrageneric groups within Lauraceae, bearing in mind that they might have evolved in parallel in different genera.

RESUMEN

A partir de la revisi\ón taxon\ómica de exsicatas depositadas en herbarios nacionales y extranjeros, se exponen los aportes al conocimiento taxon\ómico del g\énero Persea (Lauraceae) en Venezuela. Se reportan 24 especies, incluyendo una especie y dos variedades nuevas para la ciencia, nuevos reportes para el pa\ís, ampliaciones de distribuci\ón, mapas de distribuci\ón y una clave actualizada para la determinaci\ón de especies en Venezuela. Utilizando el paquete DELTA, se obtuvieron descripciones en lenguaje natural y una clave interactiva para la identificaci\ón 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. Descriptions in natural language and an interactive key for identification were obtained using Delta Software.
