patent, glossy scales, the lower ones being larger, ovate-acuminate, the upper linear 
and hair-pointed with a bullate base. Rachis similarly slender, glanduloso-pubes- 
cent and somewhat scaly. Pinnz 5—8 cm long, the coste and costule beneath 
more or less glanduloso-pubescent and furnished with bullate-acuminate scales 
much similar to those of D. nigrovenia. Seg- 
ments oblique or falcate, the basal ones some- 
what reduced, the larger serrate. Veins 5—6- 
jugate, very oblique, reaching the margins. 
Sori small, medial or supramedial, indusium 
small, fugacious, glandulose. 
D. Lindeni is different by the veins not 
reaching the margins, D. strigilosa by diffe- 
rent scales and glandular under surface.

Near D. Tonduzii, resembling it in size, 
colour and texture, but the lower pinnz in- 
cised to costa and the scales different. The 
scales of stipe and rachis, very numerous at 
the base of the stipe, are up to 1 cm long, 
pinna and base of the second pinna from patur gark-brown, glossy, P2 narro was

underside and one seen from above, xc 1!; gins furnished with small, capitate glands

middle pinna >< "i, and three segments scar by which the stipe becomes rough. Scales

of the coste beneath are similar but smaller 
with a broader, still scarcely bullate base (fig. 34). Whole leaf densely glandular- 
pubescent. Lower pinne about 4 cm long, broadest at base, fully pinnate at the 
lower half; segments (or pinnules) distinctly serrate, generally truncate at apex, 
veins 4—5 to each side, simple, reaching the margin; sori inframedial furnished 
with a glandulose indusium.
