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; costæ and veins of underside with several pa- 

 tent, long, whitish hairs, which, however, are deciduous, and several specimens 

 appear to be glabrous. Lower pinnæ shortly stalked and with a characteristic 

 long cuneate entire base, the upper ones mostly truncate at the base. Pinnæ 

 15 — 20 cm long, 2'/2— 3 cm broad, much acuminated, incised ^/s to "3 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 I), tristis belong to D. monosora 

 and U. cuneata. I have not seen the true form from Central-America, although it
