Abstract

IBARRA-MANRIQUEZ, Guillermo; CORNEJO-TENORIO, Guadalupe  and  SINACA-COLIN, Santiago. What’s done is done: taxonomic update and geographical distribution of the vascular flora of the Los Tuxtlas Tropical Biology Station, Veracruz, Mexico. Rev. Mex. Biodiv. [online]. 2025, vol.96, e965749.  Epub Mar 27, 2026. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2025.96.5749.

The main objective of this work is to update the nomenclature and inventory of the flora of the Los Tuxtlas Tropical Biology Station, located in Veracruz State, based on floristic-taxonomic literature, herbarium specimens, electronic databases, and support of taxonomists. We registered 934 species, 571 genera, and 139 families. The 20 families with the greatest number of species comprise 58.8% of the flora, highlighting Orchidaceae (108 species), Asteraceae (61), and Fabaceae (58); the most specious genera were Epidendrum (16), Piper (12), and Ficus (10). Forty-eight families (34.5%) and 410 genera (71.8%) are represented by one species. The most common growth forms were herbs (453, 48.5%) and trees (259, 27.7%). Ninety-three species (10%) are endemic to Mexico, and 29.8% of the species are shared exclusively with Central America, followed by the area encompassing Central America, Antilles, and South America (23.2%). The importance of maintaining the inventory of this conservation area in one of Mexico’s regions with the highest rates of deforestation, is emphasized.
