of the pinnae and pinnulae, otherwise naked. Fronds 100 cm. or 

 more long, deltoid, 3-pinnate. Pinnae opposite, triangular-lanceolate, 

 articulate. Pinnulae horizontal, subsessile, articulate, the lower 

 opposite, the largest + 10 cm. or more long, + 2\ cm. broad, rather 

 short-acuminate, truncate at the base, the lowest somewhat reduced. 

 Tertiary segments mostly distinct, connected by a very narrow wing, 

 the largest to ± 2 cm. long, it 8 mm. broad, oblong, obtuse, obliquely 

 cuneate at the base, with a few shallow lobes, the lowest anterior lobe 

 the largest, subauriculiform. Texture papyraceous; surfaces naked; 

 colour dark; veins 4 — 5-jugate, the lower forked. Sori in the sinuses of 

 the lobes.

(5) D. Siuithii, Jttoores — var. novoguineensis, Rst., in Fed., 

 Rep., X, 323. 



A fragment of a plant received from Luzon, determined as D. Smithii 

 Moore (leg. Elmer No. 11513], has the frond decidedly 4-pinnate, with the 

 pinnae more than 75 cm. long, + 27 % cm. broad at the base, the lowest 

 anterior pinnula much the largest, + 17'/2 cm. long, + 4 cm. broad, 

 the lowest anterior leaflet the largest, + 274 cm. long, cut down to the 

 rachis into several rhomboidal, more or less deeply incised segments + 

 6 mm. long and 2 mm. broad at the base, with the lowest anterior lobe 

 the largest, the under surface copiously provided with long, crisped, 

 articulated hairs, as are the rachises, the upper surface less copiously 

 so, here and there naked. — I believe Hooker's original diagnosis has 

 been founded on an incomplete specimen of the species.

Fronds larg, 4-pinnatifid ; main rachis livid-green, shortly tomentose, 

 spinose at the base, canahculate on the upper side. Pinnae articulate- 

 petiolate, elongate-oblong, to 70 cm. long and 30 cm. broad, acuminate, 

 the rachis like the main one but not spinose. Pinnulae subsessile, 

 elongate-oval or lanceolate, + 15 cm. long, 3 cm. broad, the apex
