AN INVESTIGATION OF THE UNIQUE PERISTOME OF THE REGMATODONTACEAE SENSU EAKIN USING THE SCANNING ELECTRON MICROSCOPE


David A. Eakin, Eastern Kentucky University, Richmond, KY, 40475


Abstract: The moss family Regmatodontaceae sensu Eakin is characterized by a peristome unique among moss genera. The author will present results from the first investigation of this peristome by means of scanning electron microscopy. This investigation verifies the previously determined species-specific characters for R. declinatus and R. orthostegius, as well as raising some new questions regarding possible differences in the sculpting of the exostome segments of these two species, and the source of papillosity in the endostome segments of R. orthostegius.
