EAKIN, DAVID A. Department of Biological Sciences, Eastern Kentucky University, Moore 235, Richmond, KY 40475. - Preliminary results of a study of the unique peristome of the genus Macrohymenium [Sematophyllaceae] using conventional and scanning electron microscopy.
The moss genus Macrohymenium [Sematophyllaceae] is
characterized by a peristome unique among moss genera. The author will
present preliminary results of an investigation of this peristome by
means of conventional and scanning electron microscopy. The outward
similarity of this peristome to that found in the Regmatodontaceae
will be discussed. The differences among species of
Macrohymenium sensu Eakin will be discussed.
Key words: Macrohymenium, peristome, Sematophyllaceae
