triangular-ovate, their racliis iianowly winged; segments of tlie fourth

(33) N. simplicifolium Hook. Kliizomc creeping; stipes tufted, strong, 

 villous upward, about 10 cm. high; frond 15 to 30 cm. high, with a 

 lanceolate-acuminate, entire apex about 3 cm. broad, and at its base 1 to 6 

 small blunt, spreading, entire, distinct pinniB, subcoriaceous ; midrib hispid 

 beneath, and the prominent veins slightly so, main veins 3 mm. apart, 

 all the veinlets anastomosing; sori miniite, indusium wanting.

(34) N. Bakeri Harrington. Rhizome erect ( ?) ; stipes clustered, light 

 brown, villous or scaly, 4 to 10 cm. high; frond oblong-oblanceolate, 10 

 to 15 cm. high, 2 to 3 cm. broad, obtuse, coarsely crenate or lobed one- 

 third the distance to the costa, with usually 2 to 4 distinct oblong-obovate 

 sessile pinnae at the base hardly as large as the lobes, papyraceous, villous; 

 veinlets 6 to 8 pairs, the majority of them anastomosing; sori small. 

 midway on the veinlets, the indusium hairy, often absent.

(35) N. canescens (Bl.) Christ. Rhizome creeping; stipe of sterile 

 frond about 5 cm., of fertile about 20 cm. high, erect, villous above; rachis 

 likewise villous; sterile frond 10 cm. more or less, high, ovate-lanceolate, 

 acute, the terminal segment sometimes almost the whole length, sometimes 

 much less than half, crenate; pinnte truncate at both ends, crenate or 

 slightly lobed toward the broad apex, papyraceous, mostly glabrous; fertile 

 frond similar except that the pinnae are usually narrower and occupy a 

 relatively large part of the frond; sori near the main veins, or irregularly 

 scattered, indusium usually absent. I follow Christ in referring this plant 

 to Blume's Gymnofjnnume canescens, though our plants are largely glabrous. 

 It is variable here as in Celebes (cf. Christ, Ann. Jard. Buitenz. 15:130).

 sterile frond 10 cm., of fertile 20 cm. high; rachis very closely villous; 

 frond 15 to 30 cm. high, lanceolate or ovate; pinnae opposite, acuminate, 

 below their apex deeply and variously lobed, crenate near the truncate, 

 sometimes auricled base, papyraceous, glabrous except for the costa; fertile 

 frond the same, sori midway on the veinlets, exindusiate.

This and the preceding two species are very close together, and probably 

 all very near .V. para»iticum.
