It is possible that this proposed new species is a form of the common Bra- 
zilian D. lugubris, which it resembles as well as 
D. nephrodioides in habit, size and venation. Still 
it lacks the scales of rachis and coste beneath, 
which are found in D. lugubris, the sori are di- 
stinctly inframedial, and the sporangia are setose 
by anchor-shaped hairs similar to those, occurring 
on the under surface. Rhizome short-creeping; slipe pi, "hos SERE ehe T) Bend

Type from Ecuador: in monte Guayapurima, Spruce nr. 4748 (RB!). 
A peculiar, thin-leaved species, resembling D. glochidiata by the anchor-shaped, 
erect hairs of the underside and rachis but otherwise very different by the longer 
pinnz, the glabrous upperside and sporangia, exindusiate medial sori, the basal 
veins united etc. The rachis is not densely pulverulent as in D. nephrodioides and 
related species, still the species has its proper place here.

Syn. Aspidium nephrodioides Klotzsch, Linnaea 20: 370. 1847. 
Type from Venezuela, Caripe, in sylvis humidis, Monrrz nr. 206 (B!). 
A variable species but easily distinguished from almost all other species by 
the dense pubescence of stellate hairs throughout the whole plant; the hairs of the 
rachis bear on a short stalk 5—6 short, normally simple branches, those of the 
surfaces are sessile and bear 3—5 long horizontal branches, which are adpressed 
to the leaf tissue; generally these hairs can only be seen by aid of the microscope; 
in certain forms rachis upwards, coste and veins above and the margins are fur- 
nished with some few, deciduous, long, simple setze. 
The oblique rhizome bears at the top several leaves on long stalks; the 
leaves have a pinnatifid apex and a large number of alternate short-stalked linear 
pinne, which are long acuminated, a little reduced towards the base and incised
