Stipes subasperous, tomentose above, ebeneous or dark-hrown like the 

 rachises, slightly paleaceous at the base and bearing there 3 — 5 subsecund, 

 black spines 2'/^ — 4 c.M. long, with many sharp, divaricating branches. 

 Fronds 3-pinnatifid; rachises tomentose above. Pinnae ± 50 c.M. long or 

 longer, gradually narrowed at the pinnatifid apex. Pinnulae 4 — 7 '^ c.M. long, 

 1 — 2 c.M. broad, oblong-lanceolate, sessile or short-stalked, the apex acuminate, 

 the point bluntish, the base truncate, the edge pinnatifid ± Vi — ^js of the 

 way to the costa. Lobes oblong, subfalcate, obtuse, crenate or serrate towards 

 the apex. Texture subcoriaceous ; colour dark-green above, paler beneath 

 where the costae and costulae are ± scaly ; veins mostly simple. Sori small, 

 of few sporangia, nearer the costulae than the edge, not reaching the apices 

 of the lobes.

 little narrower, the apex pinnatifid, acuminate, the rachis often hairy above. 

 Pinnulae linear-oblong, + 1 — 1^2 c.M. broad, the base truncate, the apex 

 bluntish, toothed, the edge cut ± V2"way down into broad, obtuse, entire 

 segments. Texture + coriaceous; costae hairy above; costules naked 

 or + scaly beneath, pinnate in the lobes ; veins simple or forked, 4— 5 on each side.
