ad basin pinnarum superiorum interdum bulbillifera. Pinnis remotis, alternis, 
subhorizontalibus, inferioribus breviter petiolutatis, superioribus sessilibus, oblongis, 
10—14 cm longis, 2!» cm latis, longe acuminatis, inferioribus vix brevioribus ver- 
sus basin breviter attenuatis, superioribus basi truncatis, supra ubique pilis ad- 
pressis simplicibus deciduis sparse strigosis, ad 
costas pilis cylindricis rufis dense setosis, infra 
inter venas glabris, ad costas costulasque pilis 
similibus pilis stellatis brevissimis intermixtis 
hirtis, ad alam 4—5 mm pinnatifidis. Laciniis 
parum obliquis, obtusis vel subacutis, versus api- 
cem leviter crenatis. Venis simplicibus, 10— 11- 
jugis, basalibus duabus ad sinum conniventibus. 
Soris medialibus. Indusiis subpersistentibus, pilis 
simplicibus dense setosis. Sporangiis glabris. 
By its peculiar pubescence different from all 
allied species with exception of D. curta and D. 
lugubriformis. Dr. Hizronymus referred STUBEL’s 
specimens to D. nephrodioides, the pubescence and 
venation of which are tolally different.

Closely allied to the preceding species, but 
leaf firmer, grey-green, throughout more densely 
hairy, especially aboye, terminating in a subsimilar 
terminal pinna, and the lower 2—3 pairs of veins 
connivent to sinus; by these two last characters it 
resembles D. tristis and allied species, but its pro- 
per place seems to be here. Rachis gemmiferous 
above, sori inframedial, small, clothed with a hir- 
sute, persistent indusium. The long hairs of rachis 
and cost are rarely red and far more numerous 
but thinner than in D. heterotricha; rachis upwards 
especially densely hirsute, the edges densely ciliate.
