a 
forked or subpinnate with a single branch to each side, not reaching the margin, 
terminating in a hydathode seen on the upperside as a narrow, oblong, brown spot; 
midvein of a posterior basal segment of an upper pinnula springs out from the costa near 
the base of the costula. Upper part of rachis and cost above densely rusty-tomentose 
by Ctenitis-hairs: costules and veins on both sides villous by long, whitish hairs, 
the margins ciliate; leaf-tissue as a rule glabrous; underside often minutely glan- 
dulose. Coste and costules laxly paleaceous beneath with lanceolate or linear, 
yellowish-brown, thin, toothed scales that are rather inconspicuous and often hidden 
between the long hairs. Sori one to each lobe near the tip of a very short anterior 
branch of the fureate vein. Indusium large, firm, castaneous, persistent, reniform 
with a very narrow sinus, glabrous or with some few long hairs at the centre, 
minutely glandular at margins. Spores small, very minutely and densely papillose. 
D. villosa has been recorded from most countries of tropical America, still it 
is, as I understand the species, apparently confined to Jamaica and Santo Domingo; 
the continental forms referred to it belong to allied but clearly distinct species. 
According to JENMAN it is frequent in Jamaica in damp woods and forests especially 
near water courses, above 2000 feet altitude. It is somewhat astonishing that JENMAN 
follows BakER in referring D. Karsteniana and D. subincisa as varieties to D. villosa. 
Besides their sori being exindusiate they differ in several other important characters.

This is the andine form of D. villosa sens. lat., agreeing with the genuine 
D. villosa in its large, persistent indusia, differing in size, cutting, colour and pu- 
bescence. — Much smaller than D. villosa, judging from the specimens seen, the
