of the lower pair truly anastomosing and sending a branch to the sinus, where 
the next pair meet. Sori medial, small, furnished with a small, ciliate indusium. 
Sporangia glabrous. — The terminal pinna is not so distinct as in Eugoniopteris; 
it is broader and deeply lobed at base, but the basal lobes is much shorter than 
the uppermost pair of lateral pinne. f

Type from Costa Rica: buissons et broussailles de Tuis, 650 m, leg. A. 
Towpuz nr. 11323 (CI, W). 
Habit of D. Eggersii and D. scabra but smaller and its rachis very hairy 
by hairs of two kinds intermixed: 1) numerous, short stellate hairs with 3—5 
short, simple branches on a short stalk, and 2) rather nume- 
rous, much longer, patent hairs, which often are cleft at the 
apex. — Stipe 3—4 dem long, sulcate, stellato-pulverulent and 
with scattered small, flat scales. Lamina membranous, 3—4 
dem long, broadest at the base, upwards gradually narrowed 
into a pinnatifid apex. Pinne all sessile, 6—7 cm long, 
1's cm broad, the edges nearly parallel, truncate at base, 
shortly obtuse at the point, the basal pairs reflexed, the upper 
ones horizontal, the upperside throughout hairy by numerous 
adpressed antrorse simple hairs; coste beneath very hairy 
like rachis, veins and leaf tissue finely pubescent by simple, 
erect hairs. Pinnzs incised scarcely more than halfway down 
to the midrib into close, falcate, obtuse, entire segments. 
Veins 8— 9-jugate, simple or, not rarely, forked, the lower 2—3 
connivent to sinus. Sori medial, furnished with a subpersi- 
stent, setose indusium. Sporangia glabrous. 
In the most complete specimen (W) the rachis bears a 
small gemma. j
