Type from Cuba orient. Monte Verde, Wricut nr. 1007, 1008 (B, S, W) — 
Specimens from the same region (Vicinity of Baracoa) were collected by PorraARD, 
E. and W. PALMER nr. 239 (W). 
Closely allied to the two preceding species, distinguished by its rigid, grey 
frond, which upwards is suddenly narrowed into a long pinnatifid apex. Scales of 
rhizome dark-castaneous, rigid. Pubescence mainly as in D. L’ Herminieri, still the 
coste beneath are lacking the 
short hairs, and the upperside 
hairy on the coste only. Pinnz 
sessile with an equal, cuneate 
base, incised .!/»—?/s of the way 
to the costa into falcate, obtuse 
or acute lobes. Veins about 10- 
jugate occasionally forked, raised 
on the upperside; the basal ones 
connivent to the sinus; keel di- 
stinct. Sori medial, rather small, 
with a reddish, persistent, slightly

Type from Brazil, Organ Mts., GARDNER nr. 190 (Kew!). Other specimens 
were collected near Rio by Graziou nr. 15760 (B, H) and Onaws (R), and in the 
state of Sáo Paulo, Serro da mar, WackET nr. 212 (R — D. supralineata Ros.). 
D. densiloba is apparently a rare species, closely related to D. L'Herminieri, 
resembling it in size, colour and pubescence. It is of a thinner texture and without 
aérophore; lower pinnz not conspicuously reduced, reflexed, the upper ones with 
a characteristic upcurved apex; pinnz less incised, the often very close, acute seg- 
ments being connected by a wing 3—5 mm broad; the keel distinct but not 
reaching the costa. Veins 9—16 to a side; sori medial or a little above the middle 
of the vein; indusium persistent, shortly pilose (not glabrous as described by 
BAKER). — The basal segments of the lower pinnz are much reduced.
