Rhizome short-creeping, the scales lanceolate, long-acuminale, brown. Sti- 

 pes none or short, approximate. Fronds obkiiplanceolate, 20 — 70 c.M. long, 

 2 — 8 c.M. broad, the apex acuminate, the base very gradually narrowed, the 

 edge commonly irregularly undulate and repand. Texture papyraceous or 

 flaccid; upper surface at length naked, lower clothed with fine, silky tomen- 

 tum; main veins oblique, connected by nearly straight veins forming 10 — 12 

 rows of narrow, longitudinal, subquadrangular areolae between the midrib and 

 edge; areolae with 3 — 6 sori in each, the rows close, forming a broad 

 mass confined to the upper half of the frond, not reaching the margin; cap- 

 sules commonly mixed with stellate hairs.

Rhizome wide-creeping, black, with the scales pale-brown or ferrugineous, 

 ovate or lanceolate, erecto-patent or recurved, finely long-acuminate, the base 

 peltate, rounded. Stipes 1—10 c.M. apart, ± l—Z^^tM. long, brown, clothed 

 with deciduous tomentum, at length naked. Fronds linear, 8 — 50 c.M. long, 



to + S/^lfir. broad, the apex bluntish, the edge recurved, the base narrowed 

 gradually inlo the stipe. Texture coriaceous, thick; upper surface at length 

 naked, lower densely tomentose with short-stalked (long-branched) and long- 

 stalked (short-branched) hairs; veins hidden; costa prominent, but covered 

 by the tomentum. Sori roundish, small, close or confluent, in 1 — 3 rows 

 between the midrib and edge, 1 -serial in the narrowest, 2— 3-serial in 

 the broadest forms, immersed in the tomentum when young.
