DESCRIPTIONS OF THE SPECIES 107 
more than two species, of which D. elongata is one, and the 
other is the present plant 
If it cannot be separated from D. spinulosa , our South 
African plants might all be included there, and A. inaequale 
Schl. discarded ; but meantime I follow Baker and also 
Christensen in calling this D. inaequalis , and omit A. spinu- 
losum Sw. 
Dryopteris inaequalis (Schl.). O. Ktze, Rev. Gen. PI. 2, 813, 1891 ; 
C. Chr. Index , 271.

Lastrea inaequale Presl. Pappe and Rawson, 12 (in part), (L. spinu- 
losum , P. and R., 13). 
Known as a South African species only, and evidently 
rare, most of the localities reported referring to D. elongata.

Plate 19. Nat. size. 
Rhizome procumbent, one to one and a half inches dia- 
meter, naked, except the crown, which has linear brownish 
scales adpressed to the involuted young fronds. Frond 
sub-coriaceous, glabrous, widest at the base, and tapering 
regularly upward, one and a half to two feet long, six to 
nine inches broad, with a compressed stipe six to twelve 
inches long, which is thickly paleaceous at the base, and 
more or less scaly upward, and through the rachis and pinnae- 
rachises, though sometimes all are naked and shining. Lower
