 covered by small adpressed subulate ferruginous scales; stipes subcaespitose, slender 

 15-26 cm. long, grooved above, polished, dark chestnut brown, and so is the rachis' 

 rarely sparsely scaly near the base, otherwise glabrous in all parts; fronds oblong-del- 

 toid, 11-14 cm. long, about 7 cm. broad at base, bipinnate, with a short simple pinnate 

 apex; the basal pinnae much the largest, 5 cm. long, 2 cm. broad, pinnate, the upper 

 ones gradually shortend and less compound, subsessile, alternate, erect-patent, the lower 

 4-6 pairs pinnate, oblong-lanceolate, with an acuminate pinnatifid apex, secondary 

 rachis castaneous beneath; the pinnules subsessile, oblique rhomboid with basal ones 

 often suborbicular, cuneate. cut on the outer and upper margin into few broad short 

 truncate sonferous lobes, entire and straight on the lower and inner sides 1-1 2 cm. 

 long, 5 mm. broad, alternate, 5-6 pairs in the basal pinnae; the terminal pinnae are of 

 same shape and size; texture thin herbaceous, light green above, paler below rather 

 pellucid, midrib distinct only in larger pinnules; veins all free, flabellate, transluscent, 

 1-2 forked; sort 5-7 on each pinnule, short, not confluent, submarginal, transversely
