Species identification
All but three bryophyte and fern specimens were identified
to species level, using Scott and Stone (1976)
and Beever et al. (1992) for the mosses, Scott (1985)
for hepatics and Duncan and Isaac (1986) for ferns.
Revised taxonomic nomenclature was adopted, in
accordance with Ratkowsky (1987), McCarthy and
Orchard (1998) and Streimann and Klazenga 2002).
