Abstract

  The roles in asexual reproduction played by leaves and gemmae of species of Calymperaceae range from one extreme, in which the fragile leaves of some species serve as propagules, through the single species in which the tips of leaves regularly dehisce to function as propagules, to the other extreme, in which some leaves are highly specialized for production, protection, and active participation in dispersal of regularly produced foliar gemmae. There is a wide variety of intermediate roles and morphologies. It seems likely that in most taxa the gemmae are detached from the parent plant by the action of rainfall. Some species of Calymperaceae have no apparent means of asexual or sexual reproduction. Suites and subsuites of species are identified based on mode (or lack) of asexual reproduction, representative examples of the anatomy and morphology of gemma production and dispersion are described and illustrated, and some implications are presented for the evolution of asexual reproduction in Calymperaceae.

  Syrrhopodon peguensis (E. Bescherelle) W. D. Reese is a new combination based on Calymperes peguense E. Bescherelle.
