A species of doubtful position, not nearly related to any other. It is possible 
that it belongs to § Cyclosorus, which the very hairy, persistent indusia seem to 
indicate, still I place it here provisionally. The lamina is narrowed downwards 
gradually and the stipe is very short, but the lowermost pinnz are not so small 
as could be expected in a species belonging to the group of D. opposita.

Type from British Guiana, upper slope of Mt. Roraima, rw THURN nr. 275 
(Kew !). 
A small species in general habit very much resembling D. sagittata, but a 
true Lastrea intermediate between D. pusilla and D. coarctata. 
Rhizome erect, sparsely scaly. Leaves densely fasciculate, practically without 
stipe, lanceolate, 15 cm long, 2'/2em broad at the middle, narrowed very gradually 
towards the base through several pairs of dwindling pinnz, firmly membranous, 
dark-green; rachis strigose, especially on the sides, glabrous in the furrow above, 
and clothed with many small, brown scales. Pinnz sessile, alternate, horizontal, 
the largest 1!/s cm long, 5—6 mm broad, obtuse, auricled on both sides of the 
base, slightly pilose on the coste and main veins beneath, underside finely glan- 
dulose, the upper and lower ones entire, the middle and largest ones crenate or 
lobed one third of the way to the midrib, margins somewhat revolute. Secondary 
veins forked in the entire pinne, in the lobed pinnz with 2—3 tertiary simple 
veins. Sori supramedial, furnished with rather large, persistent, at least red-brown, 
subglabrous indusia, Sporangia glabrous.
