5—6 to each side, close, not so oblique as in D. hirta. Upper surface rather densely 
pubescent by appressed, cylindrical, short, pale hairs, underside glandular by ovate 
or globose, erect glands, cylindrical hairs generally absent. Scales of midribs of 
pinne beneath subbullate with a broad, reddish-brown base and a rather long, 
narrow apex, which is darker along the middle, not metallic; scales of midribs of 
- secondary pinnules rather many, red-brown, not metallic, with a broad bullate, 
very inflated base and a short, concolorous apex. Indusia persistent, rather large, 
red-brown, glandular. 
Other smaller differences between D. hirta and D. oophylla may be found, but 
the said characters: shape and size of lamina, colour of scales, different glands beneath 
and the persistent sori, seem sufficient to distinguish our new species from D. hirta. 
It seems to be endemic in Jamaica, where it inhabits higher elevations.

Type from Sto. Domingo, based on PiumiER’s Tab. 43. 
PLuMIER’s plate very well illustrates this species, which by several authors has 
been confounded with D. hirta, although it is not nearly related to that species. It 
is interesting to note, how authors have misunderstood the present species. Thus 
Hooker and Baker (sp. and syn.) united it with D. hirta, and later on BAKER de- 
scribed it as a new species: N. myriolepis; the very slightly different form Aspidium 
melanochlamys Fée was, on the other hand, adopted as a distinct species and placed 
under the subgenus Polystichum! 
_ Lamina 30—40 cm long, 20 em, broad, ovate in outline, on a proportionally 
short stipe (15—20 cm long), herbaceous, of a brownish colour when dry, tripinna- 
tifid, scarcely tripinnate below. Pinnze generally subopposite, ovate-oblong, the basal 
ones a little shorter than the second pair, their lower side not or very slightly pro- 
duced, and their lower basal pinnula always shorter than the next. Secondary pin- 
nules close, decurrent, 8—10 mm broad, shortly acute, incised nearly to the midrib 
into about 10 pairs of close, oblique, obliquely acute, entire or rarely faintly toothed, 
oblong lobes, about 2 mm broad. Midveins of the posterior basal, decurrent lobe 
often springs out from the midrib of the pinna. Veins of lobes distant, oblique, 
_ about 3-jugate, not reaching the margin. Sori often one to each lobe on the basal
