AbstractThe growth of four epiphyllous liverworts,Radula jiaccida, Caudalejeunea hanningtonii, Leptolejeunea astroidea, andCololejeunea pusillavar.obtusifolia, has been followed for a period of about 18 months at three different localities in Western Nigeria over three height-ranges above the ground. The three localities experience different climatic conditions and possess different vegetation. Growth was found to be related to the size of the species, the larger ones always exhibiting faster growth. The liverworts also showed periodicity in growth, related to the wet and dry seasons. There was no period of dormancy, though growth was drastically reduced during the dry season.
