Flora of the tropical deciduous forest in a gypseous and calcareous area, Colima, Mexico
Background and Aims: The study area of La Salada basin is situated in the southern-central area of Colima, characterized by tropical dry forest vegetation on gypseous (74.5%) and calcareous (25.5%) soils. This site was visited by the eminent botanist Rogers McVaugh and is represented in the Flora No...

| description | Background and Aims: The study area of La Salada basin is situated in the southern-central area of Colima, characterized by tropical dry forest vegetation on gypseous (74.5%) and calcareous (25.5%) soils. This site was visited by the eminent botanist Rogers McVaugh and is represented in the Flora Novo-Galiciana. However, only a part of his collections has been available for consultation. The objective here is to document the diversity of vascular plants in this site providing evidence which sustains its biological relevance.
Methods: Revisions of bibliography and material in the herbaria IBUG and MICH were made. Specimens from recent fieldwork were integrated into the list. Additionally, electronic databases (IBdata and GBIF) were reviewed to obtain records of collections in sites of Colima with ecological characteristics similar to the sampled area. The Index of Taxonomic Diversity (IDT) was calculated facilitating comparisons of values for other areas with tropical dry forests.
Key results: A total of 408 taxa, 248 genera and 78 families of vascular plants of BTC in gypseous-calcareous soils of Colima were registered. Two appendices are provided: the first with authors´ collections and those in bibliography; and the second with citations of species in other gypseous-calcareous soils in Colima from databases. In the first, 368 taxa (including 16 infraspecific taxa) in 233 genera and 75 families were recorded. The families Fabaceae, Euphorbiaceae, Asteraceae, Malvaceae, Poaceae and Convolvulaceae total 48% of the reported flora. The genera with greatest diversity were Euphorbia (13), Bursera (eight), Ipomoea (seven) and Tillandsia (six). Of the species recorded 39% (144) are endemic to Mexico and this site is the type location for 23 species. The IDT calculated is 330.35 species/ln area.
Conclusions: The high floristic diversity and endemism of the area with gypseous and calcareous soils, substantiate conservation of these ecosystems which are being impacted in Colima. |

Antecedentes y Objetivos: La microcuenca La Salada, ubicada al centro-sur de Colima, cubierta por bosque tropical caducifolio (BTC) sobre sustratos yesosos (74.5%) y calcáreos (25.5%), fue explorada por el eminente botánico Rogers McVaugh para la Flora Novo-Galiciana. Sin embargo, solo parte del material colectado ha estado disponible. El objetivo del trabajo fue documentar la diversidad de plantas vasculares de la zona, para evidenciar su relevancia biológica. Métodos: Se realizaron una revisión bibliográfica y de material de herbario (IBUG y MICH) y colectas de campo para integrar la lista florística. Complementariamente se revisaron bases de datos electrónicas (IBdata y GBIF) para obtener registros de colectas en sitios de Colima con características ecológicas similares al área muestreada. Para comparar la diversidad del área con la de otros sitios con BTC se calculó el índice de diversidad taxonómica (IDT). Resultados clave: Se registraron 408 taxones, 248 géneros y 78 familias de la flora de BTC de sustratos yesoso-calcáreos de Colima. Se presentan dos apéndices, uno se basa en registros del área muestreada por los autores y otro en registros de otras áreas yesoso-calcáreas de Colima obtenidos de bases de datos. Del área muestreada se registraron 368 taxones (incluyendo 16 infraespecíficos) de 233 géneros y 75 familias. Fabaceae, Euphorbiaceae, Asteraceae, Malvaceae, Poaceae y Convolvulaceae son las familias más representadas (48% de los taxones). Los géneros más diversos son Euphorbia (13), Bursera (ocho), Ipomoea (siete) y Tillandsia (seis). De las especies registradas 39% (144) son endémicas de México y el área constituye la localidad tipo de 23. Se anotan 11 taxones no registrados antes para el estado de Colima. El valor IDT fue de 330.35 especies/ln área. Conclusiones: La alta diversidad florística y endemismo de la zona, y la singularidad del sustrato yesoso, merecen la conservación de estos ecosistemas que están siendo impactados en Colima.
