Summary Routine use of the virtual herbarium of the collections in COL (Instituto de Ciencias Naturales de la Universidad Nacional de Colombia) revealed the presence of an as yet undescribed species of Senecio amongst the material of Senecio adglacialis and S. leucanthemoides . Following subsequent herbarium studies and fieldwork, Senecio scapioides (Compositae: Senecioneae: Senecioniinae), from the Departamento de Boyacá, in Andean Colombia, was recognised and is described and illustrated; it is compared with S. adglaciali s and S. leucanthemoides . Notes on its distribution and habitat, conservation status, phenology, and etymology are also provided, and the distribution of the three species mapped.
