%X ABSTRACTTaxonomic processing of the Celastraceae was made based on morphological characters andpollen from exsiccates pertaining to the different herbaria from Colombia an some fromoutside: MO, NY y US, along with characters taken directly from plants in the field,concatenating with the distributions patterns. Besides the taxonomical study, a review of thisplant group nomenclature was made, in order to establish the valid names, those ones whichare synonymous, and species location. The characters established in the descriptions of thespecies were compared with the observed ones in the study material. The study of pollen tookinto account grain type, opening of the pores, presence of rims and ribs ambit, exine, sexine andnexine, reticulation and measurements including equatorial and polar axis and the ratio long-width of pores and colpes. Fourteen pollen samples were analyzed, belonging to 8 nativegenera, revealing that palinology makes valuable contributions in the boundary of taxons,providing valid characters, that they are complemented with the other morphologic characters.The taxonomic description of the family fits with the Colombian constituent taxons.Dichotomizing keys were made in order to identify genera and species, and descriptions of eachone of the species, as well as their distribution, citation studied material of each taxon and insome cases illustrations of the species, were drawn at least one for each genus. Eigth native and1 cultivated genera were found: Celastrus 4, andean and subandean woody scandent species.Crossopetalum: 2 species of islands of Tintip芍n and San Andr谷s and Providencia. Goupia: 1species from equatorial rain forest. Gymnosporia: 2 species, one of forest of the median valleyof Magdalena and the other of the andean and subandean forest. Maytenus considered aspreliminary synopsis, with 26 species coming of different habitats. Perrottetia with 10 species,4 of these new; 1 species from piedemonte, the rest live in andean and subandean mist belts.Schaefferia: 1 species from subxerofitic and warm places. Zinowiewia: 4 species from Andeanand subandean mist belts. Euonymus: 1 cultivated species in cold climate towns. Se adelant車 el tratamiento taxon車mico de las Celastraceae, con base en un estudio decaracteres morfol車gicos y de polen, a partir de exsicados pertenecientes a los distintosherbarios del pa赤s y a algunos del exterior como lo son MG, MO, NY y US, junto con caracterestomados directamente de plantas en campo, concatenado con los patrones de distribuci車n.Adem芍s del estudio taxon車mico tambi谷n se hizo una revisi車n de la nome
