In Herb. Mett. (B) there is found a sketch of the original specimen and from 
this and the original diagnosis I have got a fair idea of this species, which has 
been said to have a wide distribution throughout the whole tropical America. — 
Rhizome obliquely erect or creeping with a few scales, which bear stellate hairs. 
Lamina with terminal pinna, dark-green, membranous (not coriaceous); rachis and 
stem pulverulent by stellate hairs; coste and veins of underside with several pa- 
tent, long, whitish hairs, which, however, are deciduous, and several specimens 
appear to be glabrous. Lower pinne shortly stalked and with a characteristic 
long cuneate entire base, the upper ones mostly truncate at the base. Pinnz 
15—20 cm long, 2!/s—3 cm broad, much acuminated, incised !/» to '/s of the way 
down into subfalcate, acute, close segments. Veins simple, 12—14 to a side, the 
lower 4 running out to the sinus. Sori small, medial; indusium very small, 
ciliated by long, simple hairs, soon falling and in several specimens not found. 
Sporangia glabrous. 
D. tristis is distributed from Guiana to Peru, while it does not occur in 
Southern Brazil; the plants therefrom referred to D. tristis belong to D. monosora 
and D. cuneata. I have not seen the true form from Central-America, although it
