THE FERNS OF SOUTH AFRICA 
South Asia, Tropical Africa, Mascarene Islands, and New 
Hebrides. 
Transvaal. — Gathered in Transvaal by Mr Todd of Inanda, and a 
plant of it, recently found near Barberton, is growing in Mr John 
Wood’s garden at. Grahamstown; Avoca, Barberton (Galpin, 1244); 
Shilouvane, 2400 ft (Junod, 122). 
Rhodesia. — Mazoe and Umtali (J. F. Darling); Umtali (Mrs Bennett, 
Mrs Meikle, Mrs Eickhoff, Holland); Victoria Falls, Kloofs of lower 
gorge (Miss Gibbs, 180; Holland; G. Richards; J. Sim; Allen, 17; 
Engler); Zambesi (Waller); Knife Edge, Zambesi, near Victoria 
Falls, 3000 ft (Rev. F. A. Rogers, 5052); Matopo Hills, Mtchabesi 
Valley (Miss Gibbs, 316); Sebakwe, in the shelter of old workings 
(F. Eyles, 389) ; very common (locally) on the western face of the 
long range of ironstone hills in Mazoe district, at from 4500 to 
5000 ft alt. (Eyles). 
Cape Colony is credited with it in Syn. Fil ., but I have 
heard of no locality there ; probably “ Cape Colony ” at that 
time was nearly equivalent to “ South Africa” now. 
A. ROTUNDATUM Kze, described from a specimen in 
Maire’s Herbarium labelled Promontorium Bonae Spei, seems 
to be a large glabrous form of A. caudatum , paleaceous only 
at the base of the stipe, and with reniform sori. It differs in 
texture and colour from A. lunulatum , as well as in the shape 
of the sori. This is 
A. rotundatum. Kze, Linnaea , 10, 528 ; Pappe and Rawson, 52; Hk 
Sp. Fil. 2, 53. 
A. rhizophorum. Swartz, Syn. ; Kuhn, Fil. Afr. 66. 
A. caudatum , var. b rhizophorum. Hk. and Bkr, Syn. Fil. 115. 
A. Edgeworthii. Hk. Sp. 2, 14; Hk. and Bkr, Syn. Fil. 472. 
Lady Barkly, in a postscript to her revised list, writes : 
“ We have received through Dr Shaw, from Wakkerstroom, 
Transvaal, an Adiantum which seems to be a connecting 
link between A: caudatum and A. lunulatum” ; no doubt the 
same thing. It is still maintained as A. rhizophorum Sw. by 
Christensen as from South Africa and Timor Island, but we 
have seen nothing to answer to this.
