Abstract: An essay on plant hybridization in nature, acknowledging fertilization of one species by pollen of another, and reporting some fertile intergeneric crosses. Interspecific hybrids are cited in Geranium (= Pelargonium), Erica, and Mesembryanthemum (sensu latiore). A list of 34 species believed to be of hybrid origin is given with supporting notes for each. A second list of those of putative hybrid origin is also supplied.
