SCLA, a numerical taxonomic method was applied to lip morphology in the genus Polystachya Hook. (Orchidaceae) in Nigeria. The basic data matrix was prepared by coding for the presence or absence of the attributes of characters involved. The data were standardized so that the values of a particular character were transformed into values ranging from zero to one. The SCLA showed that reproductive characters are much better than the vegetative characters earlier used in the distribution of
