(Dryopteris obtusiloba (Desv.) C. Chr. 
A Natal fern, without 01; almost without indusium, which 
in Hk. and Bkr, Syn. Fil , stands as POLYPODIUM OBTUSI- 
LOBUM Desv., had been stated formerly by Baker to belong to 
one of the forms of Neph. conterminum, and on this authority 
is included in Lady Barkly’s list under that name ; but it 
is likely that Mr Baker used that name in the wide sense 
of the Conterminum group, as used in his Synopsis Filicum, 
which includes N. Bergianum Baker. At all events, Lady 
Barkly’s specimens from Buchanan, and all the other speci- 
mens I have seen so named, or named P olypodium obtusilobum , 
are identical with the larger growing forms of D. Bergiana , 
and do not answer so well to Baker’s restricted species N. 
.conterminum Desv. ; and Mr Baker wrote me that he does 
not know N. conterminum from South Africa. The only 
difference from D. Bergiana is that they have no indusium, 
and even that is a poor distinction, as in almost every case 
the specimens are in the advanced condition in which the 
more or less fugacious indusium is often absent, or can be 
seen only with difficulty. D. Bergiana is however often
