colour ochraceous-fulvous. Fertile fronds 2 — 5, narrowed gradually towar 

 the base, to 65 c.M. long, repeatedly dichotomous, pale-coloured, flocculent, t 

 tomentum adpressed; ultimate segments rather numerous (± 16 — 20) 

 each frond, lanceolate, ligulate or elongate-triangular, to 7 c.M. long, narro 

 subobtuse, rostrate, involute. Sori occupying the whole under surface of 1 

 ultimate segments, densely covered with a thick, whitish tomentum when yom 

 but less so at full maturity. — A plant gathered in Timor by Teysmann, v( 

 probably a form of this species, has the fertile fronds very coriaceous a 

 rigid, 45 — 75 c.M. long, with the ultimate segments not rostrate, the sori ofl 

 reaching from the apex of the ultimate segments to considerably below 1 

 highest sinuses.

Rhizome thick, creeping, densely scaly, bearing the fronds in more 

 less distant groups. Basal fronds 2 or more, roundish or cordate, imbrica 

 convex, entire, sinuate or lobed, 10—20 c.M. each way, afterwards brown, 1 

 lobes spreading or erect. Fertile fronds mostly 4 — 7, clustered, the sti] 

 thick, to + 5 c.M. long or longer, ± erect, the fronds 40 — 90, c.M. loi 

 cuueate at the base, 2 — 3 X dichotomously branched, with about 4 — 8 u 

 mate lobes, which are ligulate, flat, 10 — 20 c.M. long, 2 — 5 c.M. broad, w 

 the apex blunt or blunlish. Texture thick; colour pale-green; young froi 

 covered with a thin, whitish or pale-reddish, + fugacious, adpressed tomi 

 turn; areolae + hexagonal, with few free veiniets. Sori occupying + I 

 upper '/^ of the ultimate lobes.
