Background and aims: The vascular flora of Sierra de Velasco from La Rioja Province (northwestern Argentina), belonging to the extra-Andean range Sierras Pampeanas, has not been systematically studied. The goal of this work was to describe the plant diversity of the Sierra de Velasco along its altitudinal gradient (1500-4300 m).
M&M: Plant collections from 2021 to 2024 in the Costa Riojana zone of the Sierra de Velasco, were carried out. Specimens were processed and determined, and then deposited in the UNCAT herbarium and at the Centro Regional de Investigaciones y Transferencia Tecnológica de La Rioja.
Results: Two hundred and sixty-nine species grouped in 199 genera and 81 families were recorded. Asteraceae had the greatest richness of species, followed by Fabaceae, Cactaceae, Solanaceae, Poaceae, and Verbenaceae. Forty-two taxa were recorded for the first time for La Rioja Province. Species of the Monte, Chaco, Yungas, Comechingones, Puna, and High Andes phytogeographic regions are distributed in altitudinal ranges comparable with neighboring mountains. Species that inhabit the highlands of the Sierra de Velasco suggest a biogeographic connection to the Puna Húmeda.
Conclusions: This first systematic record of the vegetation of the Sierra de Velasco allows understanding its biogeographic relationships and provides key data for its conservation in face of climate change and environmental degradation. |

Introducción y objetivos: La flora vascular de la Sierra de Velasco, provincia de La Rioja (noroeste de Argentina), perteneciente a la cadena montañosa extra-andina Sierras Pampeanas, no ha sido estudiada sistemáticamente. El objetivo de este trabajo fue describir la diversidad vegetal de la Sierra de Velasco a lo largo de su gradiente altitudinal (1500-4300 m). M&M: Se realizaron colecciones de 2021 a 2024 en la zona de la Costa Riojana, en la Sierra de Velasco. Los especímenes fueron procesados e identificados y luego depositados en el herbario UNCAT y en el Centro Regional de Investigaciones y Transferencia Tecnológica de La Rioja. Resultados: Se registraron 269 especies agrupadas en 199 géneros y 81 familias. Asteraceae es la familia más diversa, seguida por Fabaceae, Cactaceae, Solanaceae, Poaceae y Verbenaceae. Cuarenta y dos especies se reportan por primera vez para La Rioja. Especies indicadoras de las fitorregiones del Monte, Chaco Serrano, Pastizales de Yungas, Comechingones, Puna y Alto Andina Cuyana se distribuyen en rangos altitudinales comparables en sierras vecinas. Las especies que habitan los Altos Andes de la Sierra de Velasco sugieren una conexión biogeográfica con la Puna Húmeda septentrional. Conclusiones: Este primer registro sistemático de la vegetación de la Sierra de Velasco permite entender sus relaciones biogeográficas y provee datos clave para su conservación frente al cambio climático y la degradación ambiental.
