description Background and Aims: The Tacámbaro Alberca is one of the three crater lakes that exist in Michoacán, Mexico. The current knowledge about the flora and vegetation of this protected area is non-existent. Therefore, our objectives are to: 1) elaborate a floristic list, 2) know the degree of endemism of the flora and the species classified under some category of risk, and 3) describe the vegetation types present in La Alberca.Methods: Twenty field trips were carried out between 2018 and 2023, to collect vascular plants with reproductive structures. Taxonomic literature, comparison with type specimens, and the support of specialists for certain taxonomic groups allowed us to determine the specimens, which were deposited in the IEB, MEXU, and MO herbaria. The vegetation was described physiognomically, according to the vertical stratification, floristic composition, dominance, and foliar phenology of the tree species.Key results: A total of 450 species were determined, grouped into 287 genera and 92 families. The most diverse were Asteraceae (79 species), Fabaceae (60), Poaceae (25), Malvaceae (16) and Solanaceae (15). The genera with the highest species richness were Desmodium (12), Ipomoea (9), Solanum (8), Bletia (7), Euphorbia, Salvia, and Stevia (5 each). Herbs were the predominant growth form (70.4%). The area presents 141 (31.3%) endemic species to Mexico and 19 are included in some risk category, according to the NOM-059-SEMARNAT-2010, IUCN, and CITES. Four vegetation types are described: Pinus forest, Pinus-Quercus forest, tropical deciduous forest, and tropical subdeciduous forest.Conclusions: The Alberca de Tacámbaro has a unique floristic richness (118 species per ha). This study contributes 345 species not registered for the flora of the municipality of Tacámbaro. A new species of Nolina is recorded and Holographis peloria, Pherotrichis villosa, and Prionosciadium lilacinum are record for the first time for Michoacán.

Antecedentes y Objetivos: La Alberca de Tacámbaro es uno de los tres lagos cráter que existen en Michoacán, México. El conocimiento que se tiene sobre la flora y vegetación de esta área protegida es inexistente. Por lo tanto, los objetivos del presente trabajo son: 1) elaborar una lista florística, 2) conocer el grado de endemismo de la flora y las especies clasificadas bajo alguna categoría de riesgo y 3) describir los tipos de vegetación presentes en La Alberca.Métodos: Se llevaron a cabo 20 salidas a campo, entre 2018 y 2023, para recolectar plantas vasculares que presentaran estructuras reproductivas. La identificación se realizó mediante literatura taxonómica, el cotejo con ejemplares tipo y el apoyo de especialistas en ciertos grupos taxonómicos. El material se depositó en los herbarios IEB, MEXU y MO. La vegetación se describió fisonómicamente, considerando la estratificación vertical, composición florística, dominancia y fenología foliar de las especies arbóreas.Resultados clave: Se determinaron 450 especies, agrupadas en 287 géneros y 92 familias. Asteraceae (79 especies), Fabaceae (60), Poaceae (25), Malvaceae (16) y Solanaceae (15) fueron las más diversas. A nivel genérico destacaron Desmodium (12 especies), Ipomoea (9), Solanum (8), Bletia (7), Euphorbia, Salvia y Stevia (5 cada uno). Las hierbas fueron la forma de crecimiento predominante (70.4%). El área presenta 141 (31.3%) especies endémicas de México y 19 están incluidas bajo alguna categoría de riesgo, de acuerdo con la NOM-059-SEMARNAT-2010, la IUCN y la CITES. Se describieron cuatro tipos de vegetación: bosque de Pinus, bosque de Pinus-Quercus, bosque tropical caducifolio y bosque tropical subcaducifolio.Conclusiones: La Alberca de Tacámbaro cuenta con una riqueza florística relevante (118 especies por ha). Este estudio aporta 345 especies no registradas para la flora del municipio Tacámbaro. Se reconoce una nueva especie de Nolina y el primer registro de Holographis peloria, Pherotrichis villosa y Prionosciadium lilacinum para Michoacán.
