Allied to D. Anniesii, from which it differs by its numerous, not adpressed, 
dirty-brown, very large scales of stipe and 
rachis and by its small, medial sori without 
distinct indusia. The scales of the coste be-

This species was founded on PruwiER tab. 49, which plate illustrates a plant 
from San Domingo; it is probable that N. aureovestitum Hk. based on LINDEN 
nr. 1901 from Cuba, Mt. Libanon is the same, but I have, however, not seen any 
Cuban specimen. It seems to be a rare species, I have seen only a single speci- 
men from Jamaica, leg. JENMAN (W); according to JENMAN it is common in 
forests on the Manchester mountains at 2000 feet altitude. 
D. vellea alone represents the subgenus in the West-Indies. It resembles 
in size D. deflexa, but in the scales much more D. cirrhosa var. eriocaulis, 
from which it differs by the glabrous leaf-tissue and fewer veins (8— 10). 
The scales are reddish, entire with a pocket-shaped base, not hair-pointed 
(fig. 3*).
