22. DRYOPTEBIS. § 2. NEPHHODIUM. 175 



Pinnae horizontal, petiolate, lanceolate-oblong, 7 '/a — 10 cin. long, 2 cm. 

 broad, sinuate-crenate or very slightly lobed, the lower ones rather 

 smaller than the others but not reduced to mere auricles. Texture 

 papyraceo-herbaceous ; rachis and midribs beneath villose and veins 

 slightly so; veins 5 — 6 on a side. Sori rather large, very dark-brown.

Veins free or the lowest pair commonly anastomosing or meeting in 

 the sinus.

Forma typica: Stipe and rachis green or brown.

 fig. 1 F^f. 



Rhizome creeping, the scales fuscous, subulate-deltoid, acuminate, 

 ciliate. Stipes + 1 — 2 cm. apart, to 5 cm. long, grooved above, hairy 

 and scaly, the scales similar to those of the rhizome. Fronds lanceolate, 

 to 45 cm. long by 12 cm. broad, pinnate, the apex suddenly narrowed 

 into an elongate-triangular, pinnatifld terminal pinna. Pinnae alternate, 

 close, sessile, linear-oblong; central pinnae largest, horizontal, + 6 cm. 

 long by I'/j cm. broad, shortly acuminate, crenated, truncate-rotundate 

 at the base; higher pinnae graduall}? ascending and abbreviated, lower 

 gradually deflexed and abbreviated, + 3 — 4 lowest suddenly reduced 

 to mere auricles. Texture coriaceous; rachis hairy and scaly; upper 

 surface puberulous; costae and main veins hairy on both sides; veins 

 + 4 — 7 on each side of the main veins, the 3 lowest anastomosing. 

 Sori numerous, occupying the 3 — 4 lower veins, nearly medial; indusium 

 reniform, setose. 



New G^iinea.

A duplicate of a plant gathered by Elmer in Mindanao (No. 11657), 

 received as D. adenophora C. Ghr.^ differs from the type in having the 

 frond smaller, the pinnae more deeply lobed, the veins less copiously 

 anastomosing, copiously setulose on both sides.
