Ferns of South Africa. 
25 
In comparison with Buchanan’s Natal List, the present enu- 
meration shows less change, and what change there is, depends 
more on different ideas of what constitutes a species, than on any 
very distinct new plants having been found. The following are 
the changes : — 
Discarded. 
New, or raised to species 
RANK. 
Pteris tremula, R. Br. 
Trichomanes muscoides, Sw. 
Blechnum Atherstoni, P. & R. 
Cheilanthes parviloba, Sw. 
Asplenium lunulatum, Sw. 
Asplenium gueinzianum, Mett.

Buchanan credited 132 species of ferns to Natal, and the above 
changes make the number now 130. 
The following species are mentioned, but not enumerated,

“ Synopsis Filicum,” the reason of the omission being explained 
under each species : —

Pellaea andromedaefolia. Fee. 
Pteris serrulata, L. 
— marginata, Bory.
