Three new species of Markea from Colombia are described and their morphological affinities and conservation status are discussed. Markea hunzikeri is different from other species of Markea because it presents a 3-lobed calyx and 3-lobed stigma. Markea huilensis shows affinity with Markea lopezii and Markea epifita, from which it differs by its exerted anthers, tubular-campanulate corolla and fruit with leathery, black, non-translucent exocarp when dry. Markea purpurea is clearly differentiated from other species in this genus by its very reduced, extra-axillary, short-pedunculate inflorescence, generally bearing one short-pedicellate or sessile flower with corolla dark purple or black inside. For new species illustrations, photographs of live plants and distribution maps are presented. As a tool for species identification of Markea, this paper is accompanied by a key to all species currently recognized in the genus. Additionally, photographs of live plants for most of the species of the genus are included.
