A Key to the family Regmatodontaceae

 

Extract from: O'Shea, B.J. 1997. British Bryological Society Expedition to Mulanje Mountain, Malawi. 9. Regmatodontaceae, Rhachitheciaceae, Rhacocarpaceae and Rhizogoniaceae (Bryopsida). Journal of Bryology 19(4).

The family contains only one genus.

Key to the species of Regmatodon (Eakin, 1975)

Seta rough throughout; endostome teeth translucent and not dotted; walls of the exothecial cells irregularly thickened, appearing collenchymatous (Distribution: As3-4) R. declinatus
Seta smooth throughout; endostome teeth translucent and densely dotted; walls of the exothecial cells regularly thickened longitudinally, the transverse walls appearing thinner (Distribution: As2-4, Afr2-3, Am2,4-5) R. polycarpus

A sterile specimen is effectively unidentifiable. However, no specimens of R. polycarpus with serrate leaf tips have been collected, although this character is exhibited by a large majority of R. declinatus specimens.
