THE FERNS OF SOUTH AFRICA 
that it has ferruginous tomentum on the under surface of the 
frond, while that of C. africanus is said by him to be nearly 
white. But as mentioned above, that of C. africanus is at 
first rufous and afterwards nearly white, at least in some 
localities. Christensen does not maintain C. fissum. 
Baker also mentions (Syn. Fil. , page 513) concerning C. 
africanus : 
“ The tropical specimens have an oblanceolate more densely matted 
frond than those of the Cape, and the scales of the rhizome narrower and 
firmer, and are separated by Mett. and Kuhn (Fil. Afr. p. 152) as a 
species under the name P. S 'chimp erianum? 
C. Schimperianus (Mett.) C. Chr. Ind ’ 200, is maintained 
by Christensen, who also includes as doubtful C. Karasekii 
Christ., Geogr . d. Fame , 112, 1910 (nomen) from South Africa.
