﻿2^. DRYOPTERIS. § 2. NEPHRODIUM. 219 



Stipes approximate or tufted, 10 — 25 c.M. long, naked or slightly pubescent. 

 Fronds lanceolate, narrowing towards both extremities, 30 — 65 c.M. long, 

 10 — 20 c.M broad. Pinnae often close and numerous, linear-lanceolate, acu- 

 minate, the base truncate, slightly cordate or broadly cuneate, the edge cut 

 down ^4 ^^ l^ss into blunt lobes; 2 — 10 lower pairs distaut, gradually 

 reduced. Texture herbaceous; rachis pubescent or naked; under surface 

 short-hairy; veins pubescent above and beneath, 5 — 6 on a side, the 2 — 3 

 lower ones commonly anastomosing. Sori medial or terminal, on the veins, 

 forming close rows; indusium often naked, persistent.

Rhizome short-creeping or erect. Stipes tufted, to 20 c.M. long, greyish, 

 nearly naked. Fronds 60 c.M. or more long, 20 — 30 c.M. broad. Pinnae 

 spreading, 7 — 25, alternate or opposite, the longest 1 — 2 c.M. broad, some- 

 times caudate, the edge entire, slightly crenate or shallowly lobed, the lobes 

 blunt; lower pinnae gradually reduced into mere auricles, often sagittate or 

 butterfly-shaped, rather distant, the normal ones rather clo-e. Texture thinly 

 herbaceous to papyraceous; rachis and under surface slightly pubescent; veins 

 4 — 6 rarely 7 — 8 on a side, the 2 — 5 lower pairs anastomosing. Sori medial 

 on the 1 — 3 lower veins, the lowest often close to the midribs.

Rhizome erect. Stipes furnished with a few lanceolate scales at the base. 

 Fronds 90 c.M. or more long, ± 45 c.M. broad, pinnate, gradually dwindling 

 down nearly to the base into small, rounded auricles. Pinnae sessile or short- 

 stalked, + 272 c.M. broad, the apex very acuminate, the edge cut down 

 only about ^g — ^j towards the costa into rounded lobes, the base truncate. 

 Texture herbaceous to papyraceous; under surface finely villose on the costae 

 and veins; veins ± 7 on each side, the 5 — 6 lower anastomosing. Sori 

 medial; indusium persistent.
