| description | Background and Aims: The tropical dry forest is one of the most threatened ecosystems in the world, mainly due to anthropic and environmental effects. The inventory of vascular flora in dry forest fragments during a period of low rainfall in the subregion North, Center and South of the department Magdalena, Colombia , is presented. Methods: A floristic inventory was carried out, at six sampling points with five transects (0.1 ha) in each one, distributed randomly, totaling 0.6 ha. All plants with a diameter at breast height (DBH) ≥ 1 cm and a minimum height of 1.5 m were included in the census and the growth form was recorded. Fieldwork was carried out from November 2019 to February 2020. The species were identified using taxonomic keys and consulting online collections, the names were corroborated in IPNI and the Catalogue of plants and lichens of Colombia. The veracity of the sampling was verified through accumulation curves and a correlation was made between the values of richness and precipitation.Key results: One hundred ninety-one species were registered, distributed in 52 families, the most represented being Fabaceae (47) and Bignoniaceae (16). The most frequent species was Handroanthus chrysanthus and the growth habit was the tree (65%). The non-parametric Bootstrap indicator was the most suitable for the number of expected species, providing a completeness percentage of 87.26%. The precipitation data were not correlated significantly (R=0.53 y P=0.27) with the total richness inventoried. Conclusions: This inventory will allow generating new scientific contributions of the flora in the tropical dry forest of the Magdalena department. The dominance of species such as Handroanthus chrysanthus and Bursera simaruba may be due to morphological adaptations expressed in physiological mechanisms to tolerate periods without precipitation. |

Antecedentes y Objetivos: El bosque seco tropical es uno de los ecosistemas más amenazados en el mundo, principalmente por afectaciones antrópicas y ambientales. Se presenta el inventario de la flora vascular en fragmentos de bosque seco durante un periodo de baja precipitación en la subregión Norte, Centro y Sur del departamento Magdalena, Colombia.Métodos: Se realizó un inventario florístico en seis puntos de muestreo con cinco transectos (0.1 ha) en cada uno, distribuidos de forma aleatoria, sumando un total de 0.6 ha. Se censaron todas las plantas con diámetro a la altura del pecho (DAP) ≥1 cm y altura mínima de 1.5 m y se registró el hábito de crecimiento. El trabajo de campo fue de noviembre 2019 a febrero de 2020. Las especies se identificaron utilizando claves taxonómicas y consultando colecciones en línea, los nombres se corroboraron en IPNI y el Catálogo de plantas y líquenes de Colombia. Se comprobó la veracidad del muestreo con curvas de acumulación y se efectuó una correlación entre los valores de riqueza y precipitación. Resultados clave: Se registraron 191 especies, distribuidas en 52 familias, siendo las más representadas Fabaceae (47) y Bignoniaceae (16). La especie más frecuente fue Handroanthus chrysanthus y el hábito de crecimiento fue el de árbol (65%). El indicador no paramétrico Bootstrap fue el que mejor se ajustó al número de especies esperadas, arrojando un porcentaje de completitud de 87.26%. Los datos de precipitación no se correlacionaron significativamente (R=0.53 y P=0.27) con los totales de riqueza inventariados.Conclusiones: Este inventario permitirá generar nuevos aportes científicos de la flora en el bosque seco tropical del departamento Magdalena. La dominancia de especies como Handroanthus chrysanthus y Bursera simaruba puede deberse a las adaptaciones morfológicas expresadas en mecanismos fisiológicos para tolerar periodos sin precipitaciones.
