(80) A. Oelangeri, Kme; — var. acuminatum, Rst., in Fed., Rep., 

 V, 373. 



Fronds + 5—15 cm. broad; pinnae horizontal or nearly so, some- 

 times somewhat deflexed, blunt to acute or acuminate. — Very variable. 



War. acianiinatuni : Pinnae narrow, elongate, to 12 cm. or more 

 long, 8—10 mm. broad above the base; segments arcuate-incurvate, very 

 oblique, imbricate; several lower segments forked. — Rhizome, stipes 

 and lower half of the fronds unknown. — Perhaps a distinct species. — 

 New Guinea.

Rhizome probably scandent, obtusely angular, sparingly dark-fusco- 

 squamulose. Stipes remote, about 15 cm. long, provided like the rachises 

 beneath with scattered dark-fuscous, ovate-lanceolate, acute, sparingly 

 denticulate-flmbriate paleae. Fronds elongate-ovate, 30 — 40 cm. long, 

 8—12 cm. broad, acuminate, 3-pinnatifld, the main rachis winged in the 

 upper part. Pinnae many, shortly petiolulate, lanceolate, straight or 

 falcate, bluntly acuminate, the rachis winged; largest pinnae horizontal 

 or nearly so, sparingly and coarsely toothed at the apes, l'/^ — 2 cm. 

 broad . at the base ; higher pinnae growing gradually smaller and more 

 ascending; lowest pinnae somewhat abbreviated, deflexed. Pinnulae 

 close, the higher oblique, subcuneate, 1 '/^ — 2 cm. broad, simple or spar 

 ingly and shallowly 2 — 3-lobed at the obliquely rotundate-truncate apex, 

 the lower horizontal or nearly so, rhomboidal-oblong, sparingly incised, 

 i. e. partly shallowly lobed partly pinnatifid. Ultimate lobules close 

 oblique, blunt, the lowest anterior the longest, similar to the higher 

 pinnulae but shorter. Texture subcoriaceous ; costae and costulae promin- 

 ent above ; veins above slightly prominent or rather depressed and provided 

 at the apex mth a short, linear impression; surfaces naked. Sori linear 

 or linear-oblong; indusium coriaceous, pale-yellow-brown. — The whole
