Rhizome slender, short-creeping, the scales minute, adpressed, linear, 

 brown. Stipes slender, naked, deciduously scaly near the base, ± l^j^ — 1% 

 c.M. long. Fronds triangular, ± 5 — 7^2 cM. long, 4 — 9 c.M. broad at the 

 base, pinnate, the lower pinnae + spreading, pinnate again, ± 2 c.M. broad 

 at the base. Ultimate segments oblong to linear, 5 — 20 m.M. long, l'/2 — ^Vi 

 m.M. broad, the base cuneate, the edge, crenate or bluntly toothed to lobed, 

 the point narrowed, bluntish. Texture subcoriaceous ; rachis and surfaces 

 naked; veins 1 to each tooth or lobe. Sori terminal on the crenations, 1 to 

 each; indusium firm naked, suborbicular, small. — The description is taken 

 from specimens gathered by Hallier, determined by Christ. — Baker's des- 

 cription: "Fronds pinnate, S^j^ — 5 c.M. long, 8 — 9 m.M. broad, with the pin- 

 nae rhomboid, obtuse, 3-lobed," is probably taken from a young specimen.
