Preface. 
J. Ffolliott Darling, Esq., of Umtali, for a parcel of 25 
species collected in Mashonaland, which came to hand 
after all the rest of the book had gone to press, and which 
as the ferns of that distant region are previously unre- 
corded, I am very pleased to be able to enumerate in an 
appendix. As this parcel contains several species 
from South Africa, previously unrecorded, except by 
Sanderson, it should encourage some of the now numerous 
visitors to Mashonaland to send down specimens of what 
may come in their way, and I shall be gratified to receive 
and report upon whatever may be so sent. 
I do not anticipate that many more species of Ferns 
will ever be found in Cape Colony, but the w r hole region 
north of the Orange, Vaal, and Umvolosi Rivers is still 
botanically, almost a terra incognita , and doubtless contains 
many still unrecorded species.
