Rhizome wide-creeping, the scales + dense, ferrugineous, lanceolate, long- 

 acuminate, peltate at the base. Stipes scattered, 10 — 50 c.M. long. Fronds 

 30—60 c.M. long, 15 — 40 c.M. broad, deltoid-lanceolate, 4 — 3-pinnate. Lowest 

 pinnulae with oblong-rhomboidal divisions, the segments of which are entire 

 or deeply and finely inciso-pinnatilid with sharp teeth. Texture herbaceous; 

 surfaces naked; veins fine, blackish, I in each ultimate segment Sori minute, 

 solitary near the base of the segments, ± 2 — 6 to each tertiary division, 

 terminal on very short veinlets and therefore often appearanlly medial on the 

 ultimate veins; indusium broad, semiorbicular or subcordate.

Rhizome strong, woody, wide-creeping, the scales dense, spreading, su- 

 bulate, membranaceous, peltate at the base. Stipes erect, straight, naked, + 

 15 c.M. long. Fronds oblong-lanceolate, ± 45 c.M. long, 20—25 c.M. broad, 

 3-pinnatifid, sparingly hairy on both surfaces; rachis hairy, narrowly winged. 

 Pinnae lanceolate, the central and lowest longest, subspreading, ± 3 — 4 c.M. 

 broad. Pinnulae oblong, adnate, decurrent, deeply pinnatifid, the lobes close, 

 oblong, bluntish or acute. Sori solitary at the base of the lobes; indusium 

 subtriangular-oblong. — Hardly diflereut from H. viscidula, v. A. v. R. It is 

 much like Davalia hirsuta, v. A. v. /?., but totally different in the structure 

 of the indusium.

Rhizome wide-creeping, densely scaly, the scales with the base rounded, 

 adpressed, reniform, the apex spreading, long-acuminate to filiform. Fronds 

 5 — 4-pinnatifid, + 35 c.M. long, lo ± 22 c.M. broad, acuminate, the lower 

 pinnae shorter than the following. Pinnae sessile, oblong-lanceolate, acuminate, 

 to + 12 c.M. long. Pinnulae close, to 27j c.M. long, erecto-patent, lanceolate, 

 bluntish or acute, free and decurrent at the base or more or less confluent, 

 cut down to a ± winged rachis into toothed or pinnatifid segments to 5
