5em broad, sessile or very shortly 
stalked, lower ones much reflexed, incised scarcely halfway to the costa into a little 
falcate, obtuse lobes. Terminal pinna rather distinct with a bud at base. Rachis 
slender, sparsely soft-hairy, lamina otherwise 
quite glabrous, but the surfaces often minutely 
warted. Veins 15—16-jugate, the lower 3—4 
pairs connivent to a cartilagineous membrane 
below the sinus; the basal posterior vein raises 
always from the costa. Sori a little infra- 
medial, indusium small, deciduous, ciliate. 
Sporangia glabrous.

Type from Brazil: Sao Paulo, Santos, 
H. MosÉN nr. 3545 (Rg fol. fert.; S fol. ster.). 
Rhizomate repente, dense radicante, apice 
squamis rufis, latis pilis furcatis sparse ci- 
liatis, dense onusto. Stipite 6'/» dem longo, 
angulato, stramineo, glabro. Lamina ovata, 
‘ca.4 dem longa, pinnata cum impari, pure vi- 
ridi (infra pallidiore) herbacea vel submem- 
branacea, glaberrima. Pinnis lateralibus 7-jugis, 
inferioribus oppositis, 4cm inter se remotis, 
breviter petiolulatis, superioribus alternis, su- 
premis sessilibus, mediis 20 cm longis, medio 
3 cm latis, acuminatis, basi cuneata subintegra, 
ad medium pinnatifidis. Laciniis approximatis, 
subfalcatis, 5 mm latis, obtusis vel subacutis. 
Venis simplicibus, 9—11-jugis, inferioribus 4—5 
ad sinum conniventibus. Soris inframedialibus, 
parvis, indusiis persistentibus rufis sparse 
ciliatis tectis. Sporangiis glabris. 
This new species seems different from all 
other Brazilian species. It is nearest D. mo- 
nosora, which it resembles in shape of pinnz 
and venation, but it is entirely glabrous and 
without scales on rachis, has a distinct ter- 
minal pinna, the sori are inframedial and 
the stipe much longer. In general habit it

habit, much reduced. 
resembles JD. paucipinnata, but it is much more thin-leaved and the sori are 
inframedial.
