This description was drawn from Mutis 895, collected in Colombia, locality unknown. Although the specimen compares favorably with the photograph of the type from the Berlin Herbarium, there remains the possibility that the two plants may belong to different species. More ample material and examination of an isotype may be necessary in order to establish the identity of M. villosa.
