Observations of the gemmae of 135 specific and subspecific taxa of Calymperes, Mitthyridium, and Syrrhopodon reveal that the gemmae of most taxa have a generalized morphology. However, the morphologies of some of the gemmae differ among species and s

World-wide, 15 taxa (11% of the 137 studied) of the three traditional genera of Calymperaceae (s.s.) regularly produce gemmae sequentially on multicellular stalk-like foliar structures referred to here as gemmipars. Individual gemmiferous leaves give

Constant extreme leaf dimorphism in the moss family Calymperaceae, involving evolution of the gemmiferous leaf of some species into a rod-like essentially naked costa or a narrow tube-like or channeled shaft, occurs more or less consistently in five
