 Hk., Spec. Pil., I, tab. LIX, A; Bedd., Perns Br.L, I, tab. CVII. 



Rbizome stout, creeping, the scales linear-lanceolate, dense, ferrugineous 

 or pale-brown, with the base truncate, not peltate, the edge, entire or beset 

 with short, spreading teeth or ciliae, the apex acuminate or acute, not ad- 

 pressed, deciduous. Stipes firm, erect, 15 — 30 c.M. long, naked. Fronds 

 60 — 90 c.M. long, 3-pinnatifid to 4-pinnate. Lower pinnae often 30 c.M. 

 long by 15 c.M. broad. Ultimate segments linear-oblong, toothed. Texture 

 coriaceous; surfaces naked. Sori numerous, 1 to each tooth of the ultimate 

 segments ; indusium balf-cupshaped, often + 1 '/a X ^s long as broad, the 

 apex .at some distance (± '/j — 1 m.M.) from the margin of the segment.

Rhizome stout, wide-creeping; scales adpressed, black, white when young, 

 the base roundish, peltate, persistent, the apex finely acuminate, the margin 

 beset with spreading, cobwebby, deciduous, adpressed, interlaced fibres al- 

 together forming a dense, flat coat to the rhizome. Stipes distant, strong, 

 erect, 10 — 20 c.M. long, naked. Pronds ovate-deltoid, 18—60 c.M. long, 15 — 

 40 c.M. broad, 3-pinnatifid to -pinnate, the apex with a moderately broad, 

 undivided centre. Ultimate segments ovate-rhomboidal, ± 3 X as long as 

 broad, daoply i toothed, narrower and sharper in fertile fronds. Texture coria- 

 aceous; surfaces naked. Sori in the teeth, sometimes with 1 — 2 horns 

 beyond ; indusium semicylindrical, + 2 X as long as broad, the apex nearly 

 or quite reaching the edge of -the frond. 



War. caudata: Ultimate segments acuminate to caudate. 



Var. Eiindleyi : Pinnulae more divided^ with narrower segments. 



Var. ornata: Ultimate segments broad, slightly cut.
