Recent trends in numerical taxonomy, with special reference to the classification of flowering plants, are reviewed. These advances are discussed under the following broad headings: the choice and scoring of characters and OTU's; the estimation of taxonomic resemblance; the representation of taxonomic structure; cladistics; and discrimination and identification. There is considerable activity on problems involving homology, numerical coefficients of resemblance, and clustering methods. The numerical study of cladistics is also of special interest, but it poses some very difficult problems. It is now evident that numerical methods can yield acceptable classifications, and they much increase taxonomic understanding of the groups that are examined. They are also valuable in many other branches of systematics.
