Abstract


A commented sy nopsis of the endemic taxa of Colombian slope of the Serranía of Perijá is presented, after the revisión of the collections of vascular plants deposited in the Colombian National Herbarium (COL) and an additional analysis of their distribution range. A total of 69 endemic taxa was located in the Massif of Perijá; we found 54 taxa for the Colombian slope (48 species, 5 subspecies and 1 variety) belonging to 16 families and 41 genera, and they represent 3.6% of the total vascular plants registered for the Colombian slope (1510 taxa). The richest families in endemic species are: Asteraceae (18 taxa), Acanthaceae (8 taxa), Labiatae (6 taxa) and Scrophulariaceae (4 taxa); most of the genera (70.7%) have neotropical affinities. The Paramo zone hold 46% of the endemic taxa. With reference to the biotypes, the herbaceous and shruby plants are the most diverse making up 46% and 41 % of all endemic taxa. Additionally, we reported 15 taxa that formerly were considered endemic either of the Colombian side of Perijá or Sierra Nevada de Santa Marta, and now are present in both áreas.
