Pinnae more or less oblique, the lowest 2-pinnatifid to 2-pinnate. 



(Ha) H. introrsa, Christ, in Nov. Guin., VIII, Eot., 160. 



Rhizome wide-creeping, black-brown, clothed with narrow, lanceolate, 

 brown scales. Stipes distant, + 4—10 cm. long, slender, rigid, terete, 

 castaneous, naked or provided with a few scattered, brown, lanceolate 

 scales. Fronds triangular, ± Y'/o — 17 '/a cm. long, the fertile ones larger 

 than the barren, 3-pinnatifid at the base, acuminate, the main rachis 

 sulcate, more or less marginate. Barren pinnae close, + 8 — 16 pair, 

 spreading, opposite, the central produced at the upper base, the lowest 

 stalked, deltoid-oblong, nearly equal on both sides at the base, ± 2—4 

 cm. broad, blunt. Pinnulae + 7 — 14 pair, the lower oblong, blunt, 

 approximate, + V2 — 1 cm. broad, cut down to a winged costa into close, 

 obtuse, entire or crenate segments. Fertile pinnae contracted, more remote ; 

 pinnulae not close, rather copiously serrate or serrato-pinnatifid, the teeth 

 falcate, acute. Texture coriaceous ; colour brown-green ; rachises and_ 

 costae provided with a few scattered, brown, crisped scales ; veins hidden. 

 Sori numerous, intramarginal ; indusium transversely oblong or roundish. 

 — Near H. vestita Moore but in aspect distinct from it.

Rhizome wide-creeping, the scales brown, acute, lacerato-cihate when 

 young, lanceolate, peltate near the base. Stipes scattered, 272 — 7'/2 

 cm. long, deciduously scaly. Fronds ovate, + 5 — 8 mm. long, 3 — 6 cm. 

 broad, the barren ones 8-pinnate at the base. Pinnae erecto-patent, 

 pinnate, the lowest the largest, with the lowest posterior pinnulae pinnate ; 

 segments oblong, erecto-patent, the largest to + 5 mm. long and 2 mm. 

 broad, toothed, the teeth relatively long and narrow, rather lobe-like, blunt. 

 Fertile fronds with the segments narrower, toothed, the teeth relatively 

 distant, short and broad, very blunt, rather rounded or truncate, the 

 largest bluntly toothed again. Texture very thick and rigidly coriaceous; 

 under surface scaly, ■ the scales very caducous in the barren but more
