(1) C lancirolia, v. A. v. R. 



Ehizome creeping, intricate, black wlien dry, clotlied witli deciduous, 

 brown, lanceolate, acuminate, entire, fragile scales. Stipes more or less 

 scattered, winged, 10 — 45 cm. long, those of the fertile fronds the longer 

 ones, naked, the unwinged portion 5 — 30 cm. long, the wing narrowly 

 linear-cuneate, passing gradually into the frond. Fronds lanceolate, acum- 

 inate, the point blant to acute, the edge subentire or irregularly sub- 

 sinuate; barren fronds + 25—30 cm. long, 4 — 6 cm. broad; fertile fronds 

 somewhat smaller. Texture thin-coriaceous; surfaces naked; costa and 

 main veins prominent, the latter not reaching the margin, straight or 

 somewhat flexuose, spreading, the lower growing gradually more irregular, 

 wanting in the wing. Sori compital or on free veinlets; receptacles 

 roundish to shortly linear, the longer ones straight, curved, subcircular 

 to irregularly flexuose or branched, scattered or often placed in rows 

 which are parallel or subparallel to the costa or the margin. 

 Celebes. 



(2) C pteridiforauis, v. A. v. u. 



Stipes ± 20—25 cm. long, brown to purple, glossy, when young 

 very minutely puberulous, the hairs deciduous, purple-brown, intermixed 

 with scattered, deciduous, fuscous, linear-subulate scales leaving the stipes 

 rough or roughish by their persistent bases. Fronds + 10 — 20 cm. long, 

 nearly as broad, the fertile the smallest, deeply 3-fld. Segments lanceolate, 

 mostly broadest at or near the middle; central segment 8 — 16 cm. long, 

 2 — 4 cm. broad, acuminate, the edge narrowly revolute, apparently 

 thickened, entire or irregularly and shallowly repando-undulate ; lateral 

 segments similar to the central one but smaller, suberecto-patent, shortly 

 decurrent upon the stipe, not rarely forked on the lower side with a 

 spreading, short and blunt or long and acuminate auricle. Texture Arm- 

 herbaceous, subpapyraceous ; surfaces naked ; central ribs of the segments 

 prominent beneath, minutely deciduously puberulous above ; . main veins 

 distinct; areolae numerous, with free veinlets. Sori numerous, partly 

 terminal on free veinlets, partly running along free or anastomosing
