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

 nearly naked. Fronds 60 c.M. or more long, ^i0---^9- c.M. broad. Pinnae 

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

 times caudate, the edge entire, ^iligtoly crenate or «haMeW^ lobed, the lobes 

 blunt; lower pinnae gradually reduced ixtbesumamkriuumim, often sagittate or

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

 4 — 6 rarely 7 — 8 on a side, the 2 — 3 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, ± 2'/2 c.M. broad, the apex very acuminate, the edge cut down 

 only about V6~V5 towards the cosla 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.
