The Ferns of South Africa. 
W. Burgessiana, Gerrarcl MSS. ; Hk. and Bkr. Syn. Fil. 48 ; Kuhn, 
Fil. Afr. 209. 
Under rocks, in South Africa only. 
Eastern Province and Transvaal (Lady Barkly). 
Natal. — Tugela River ; Lyndoch Farm, Nottingham; (McKen.) Liddes- 
dale, Karkloof, Mount West, Drakensberg at Cathkin (Buchanan). 
Under the name Woodsia mollis, J. Sm., McKen gives the 
description from “ Syn. Fil.” of that species, and quotes as local- 
ities Bushman’s River (Gerrard), and Drakensberg. This seems 
to have been a mistake as it is not included by Buchanan, nor in 
“ Syn. Fil.” ; while Lady Barkly assumes it to be W. Burgessiana. 
It may also possibly have been some cut form of Gymnogramme 
cordata which occasionally approaches some of the Woodsias in 
appearance. 
Genus VII. — Davallia. Smith. 
Sori marginal or intra-marginal, roundish, terminal on the veins. 
Indusium united below and (in our species) at the sides, and open 
only at the outer edge. A large genus with many species of diverse 
habit, and some of them having little natural connection with 
others except the form of the involucre. 
Key to the species : — 
§ Fronds jointed to the rhizome ; involucre coriaceous, marginal ; frond 
firm ; rhizome creeping (Eudavallia). 
16. D. nitidula, P'rond deltoid, 4 pinnatifid, glabrous, sub-coriaceous. 
§§ Stipe continuous with the rhizome. Involucre membranaceous, intra- 
marginal ; rhizome creeping (Microlepia). 
17. D. Speluncse. Frond deltoid or ovate deltoid, 3-4 pinnatifid, softly 
herbaceous, villose on the under surface. 
§§§ Crown tufted. Sori in marginal pouches at or near the apex of a 
pinnule (Loxoscaphe). 
18. D. concinna. Frond oblong lanceolate, 2 pinnate, coriaceous, 
glabrous. 
16. Davallia nitidula. Kunze. 
Plate X. Nat. size, b Part of pinnule, magnified. 
Rhizome very stout, and set with most abundant linear, almost 
hair-like rusty brown scales. Frond deltoid, three pinnate, nine 
to twelve inches long, six to nine inches broad, on a firm wiry
