Much as this is allied in habit and geneial appcaiance to 
the South American NoihochlcBna rufa (see Tab. LII. of 
this volume) and to some other species of that Genus, and 
of Cheilanthes of S. America, it is in reality extremely 
different. The caudex is long and creeping, clothed with 
imbricating, subulate, erose scales, which aie veiy rigid in 
consequence of the broad black costa which runs through the 
centre. The pinna; are green, and free from tomentum above, 
beneath densely woolly, sometimes rich tawny or ferruginous, 
sometimes nearly white. The margin is not reflexed, nor at 
all involucriform, so that the black capsules are quite exposed, 
forming a continuous line along the margin. 
This is well described by Pappe and Rawson in their Synop- 
sis of the Ferns of S. Africa, and is very rare in the Colony, 
only one locality having yet been discovered, and that was 
detected by the Rev. Mr. Whitehead. I am indebted to 
Wm. Rawson, Esq. C.B., and to Rear-Admiral Sir h rederick 
Grey,. K.C.B., for fine specimens.
