4-jugis, marginem non attingentibus, mediani laciniae basalis posterioris e basi vel 
interdum supra basin costulae exeunte. Costis costulisque superne antrorsim strigo- 
sis et venis setis nonnullis deciduis sparse instructis, parenchymate paginae superi- 
oris glabra; marginibus ciliatis; pagina inferiore ubique, imprimis ad costas costulas- 
que pilis albidis patentibus (ad parenchyma erectis) longioribus brevioribus inter- 
mixtis dense pubescente. Costis squamis parvis, fuscis, minute dentatis, lanceolatis, 
inter pubescentiam plerumque occul- 
tis, sparse onustis. Soris inframediali- 
bus, exindusiatis; sporangiis laxe 
coacervatis. 
This is, certainly a most distinct 
species, different from D. Karsteniana, 
to which Curist referred it as a va- 
riety, by its much smaller size and 
dark-green colour. In pubescence it 
comes next to D. villosa, in scales to 
D. subincisa. The rachis has small 
raised points but is not red-spotted 
as several other species of the group.

Stipe (soon glabrescent), rachis size; base of a superior secondary pinnula, * 2. 
and coste beneath densely rufous- 
tomentose by short, articulated hairs and clothed with bright-brown, thin, entire, ovate- 
lanceolate, mostly appressed scales, which are particularly numerous on the costz; basal 
scales darker and stiffer. Lamina subcoriaceous, bright-brown when dried, ovate, 
about 50 cm long, quadri-tripinnatifid. Pinne 10—15 cm long, acuminate. Pinnules 
patent, oblong, obtuse or shortly acute, 3—4 cm long, 1 cm_ broad, sessile, the 
upper adnate-decurrent, pinnatifid nearly to the costula into oblong, close tertiary 
segments, the apex of which is rounded behind. A posterior basal segment of an 
upper pinnula is broadly adnate to the costa with the midvein springing out from
