R. Garilleti et al., Peristomal ornamentation, a precise character for discrimination of Ulota bruchii and U-crispa (Bryopsida, Orthotrichaceae), J BRYOL, 22, 2000, pp. 273-278
A comparative study of structure and ornamentation of Ulota bruchii and U.
crispa peristomes is reported. New peristomial characters and those previou
sly suggested are recorded and discussed, and characters enabling an accura
te discrimination of the taxa are proposed. Among them, the endostome struc
ture and ornamentation are the characters that afford the most accurate dis
crimination.
