Abstract

Barriera, G. (2023). Taxonomy and nomenclature of South American Aquifoliaceae I: Ilex from Ecuador with the description of two new taxa. Candollea 78: 53–78. In English, English and Spanish abstracts. DOI: http://dx.doi.org/10.15553/c2023v781a6

Ilex L., the only genus of the family Aquifoliaceae, is represented by 500–600 species. It is distributed nearly worldwide but mainly in tropical and subtropical regions. In Ecuador it is mainly found in the Andean region, thriving in the montane forest and subparamo ecosystems. A revision of the Ecuadorian species was undertaken in the framework of the Flora of Ecuador. The taxonomic and nomenclatural results are presented here. Thirty-three (33) Ilex taxa (32 species and one variety) are recognized in Ecuador. Among all the taxa linked to Ecuador, holotypes for 51 names have been located, 23 names are lectotypified, one name is neotypified, and 26 new synonyms are proposed. Two new taxa are described and illustrated: I. cochlearifolia Schlüssel & Barriera and I. laurina var. tenuifolia Barriera.

Ilex L., el único género de la familia Aquifoliaceae, está representado por 500–600 especies. Se distribuye casi en todo el mundo, pero principalmente en las regiones tropicales y subtropicales. En Ecuador se encuentra principalmente en la región andina, creciendo en los ecosistemas de bosque montano y subpáramo. Se realizó una revisión de las especies ecuatorianas en el marco de la Flora of Ecuador. Los resultados taxonómicos y nomenclaturales se presentan aquí. Se reconocen 33 táxones (32 especies y una variedad) en Ecuador. Se han localizado los holotipos para 51 nombres, así como 23 nombres son lectotipificados, uno es neotipificado y 26 nuevos sinónimos propuestos. Se describen e ilustran dos táxones nuevos: I. cochlearifolia Schlüssel & Barriera e I. laurina var. tenuifolia Barriera.
