A similarity test is the first element for recognizing phylogenetic homology. Then, character congruence helps to screen homologous states for phylogenetic inference. We analyzed quantitative variation in the characters of seta length, capsules, perichaetial leaves, vegetative leaves, and leaf cells among 16 species of Braunia (Hedwigiaceae) worldwide. Twenty three measurements were taken from 220 specimens using the morphometric software INPAD or Image ProPlus. We did analyses of variance followed by multiple range tests for each character. The groups of taxon means revealed by these analyses were used to define the characters states that we recognized. These morphometriccharacters together with non-quantitative characters were then analyzedcladistically.
