Abstract:Natural hybridization in the genus Colletia (Rhamnaceae). Natural hybridization between two Chilean species of Colletia is assumed on the basis of morphological evidence. The characters of both species, C. hystrix Clos and C. ulicina Gill. & Hook., and those of their putative hybrids are described. The morphological intermediacy of the assumed hybrids is tested through Wells' distance diagram.
