Stipes tufted, black-brown, naked, 15 — 30 c.M. long. Fronds deltoid 

 2-pinnate, 15 — 23 c.M. long, naked; rachis black-brown, naked. Pinnae oppo- 

 site, paucijugate, lanceolate, often conspicuously caudate, the lowest largest, 

 forked at the base. Segments linear, contiguous, multijugate, entire, arcuate- 

 ascending, adnate. Sori not reaching the apices of the pinnulae; indusium 

 naked, broad, persistent, firm. — Near Pt. Griffithiana, Hk., (Spec. Fil, If, 

 tab. CXXIII, A). — If this plant is the same as found at the same locality 

 (Andai) by Teysmann, then the segments are very irregular, varying from 

 1 — 30 m.M. (mostly ± 20 m.3I.) long, joined at the base, the edges broadly 

 crenate, the sori lateral on the fully developed segments, but terminal on the 

 reduced ones.

Stipes tufted, to 16 c.M. long, firm, erect, naked. Fronds pinnate with 

 1 — 2 pinnae on each side below the terminal one, the lowest pair forked at 

 the base on the lower side in the fully developed plants. Pinnae and fork 

 branches of the lowest pinnae lanceolate, acuminate, pectinato-pinnatifid, to 

 15 c.M. long, to 8 c.M broad, the apex crenato-serrate. Lobes, linear-oblong, 

 falcate, often broader upwards, erecto-patent, to 4 c.M. long, to 1 c.M. broad, 

 not rarely shorter and narrower in the fertile than in the barren fronds, 

 crenate throughout or towards the rounded or bluntish apex only. - Tex- 

 ture coriaceous ; surfaces naked ; veins very obscure, intermixed with numerous, 

 fine, spurious veins. Sori not reaching the apex of the lobes. 



Var. ornata: Fronds provided with broad, whitish" or pale-grey-green 

 bands running down the centre of the pinnae.

Rhizome very short, crowned with lanceolate-setaceous, cinnamon-coloured 

 scales. Stipes close, 10 — 25 c.M. long, slender, erect, naked, rubro-stramineous, 

 sparingly scaly at the base. Fronds orbicular-ovate, + 10 — 15 c M. long, 

 3— 5-foliale. Pinnae cut down nearly or quite to the costa, the lowest ones
