 narrowed gradually into the short stipe ; upper surface soon naked, sjjM^du- 

 plicato-canaliculate when dry, lower densely clothed with subajj^i^ed, fer- 

 rugineous tomenlum. Sori rather large, in 1—2 irregular^ptftvT on each side 

 of the costa, immersed, but elevated above the tortlentum, occypying the 

 upper '/j — ^/a of Ihe fertile frond, but somelj«r^ covering the whole under 

 surface. — Plants gathered in New Guiana by Dr. Versteeg, which may be 

 a form of this species> have the Mfrm ami fertile fronds subsessile, the bar- 

 ren oblong, rounded at thsyit^x, cuneate, rounded or cordate at the base; 

 fertile fronds with th^xfoung sori deeply immersed, and the cavities closed 

 by a small, TOwtHm, lid-like, deciduous lateral outgrowth of leaf tissue co- 

 vered yn^/^nS^e, globose tufts of densely crowded, very long-stalked, ferru- 

 ginMjjHs^ellate hairs, the tufts + 2 — 5 m.M. each way.

Rhizome wide-creeping, the scales dense, peltate, dark-coloured, ovate or 

 lanceolate, with the base rounded, the apex blunt, acute or acuminate, the 

 edge ciliate, pale-brown or whitish. Stipes 1 — 3 c.M. or more apart, '/s — ^ 

 c.M. long, firm. Fronds dimorphous. Barren fronds oblong, linear or spa- 

 thulate, 2 — 12 c.M. long, 1—2 c.M. broad, the apex blunt, the edge entire, 

 tlie- base cuneate or gradually narrowed. Texture rigidly coriaceous, thick; 

 costa distinct; veins hidden; upper surface naked or nearly so, lower thinly 

 tomentose, the stellate hairs abundant but not crowded, caducous. Fertile 

 fronds linear, longer than the barren ones, 8 — 30 c.M. long, 4 — 10 m.M. 

 broad, with the edges more or less recurved, on stipes 1 — 8 c.M. long, the 

 tomentum thicker, woolly (the hairs densely crowded) in the soriferous 

 part of the frond. Sori small, often crateriform, occupying the upper '/j — 

 ^/j of the frond, immersed, hidden in the tomentum when young. — Ferns 

 with the habit of Drymoglossum heterophyllum, C, Chr. in the smaller forms. 



"Var. minor: Ferlile fronds subsessile, ± 6 c.M. long, 3—6 m.M. 

 broad in the fertile region.
