lobes, the base broadly cuneate and auricled on the upper and more narrowly 

 cuneate on the lower side. Texlure coriaceous; rachis deciduously scaly; 

 veins very oblique, Sori linear, the higher subparallel and nearly close to 

 the costa, occupying the lowest part of the veins. — Hardly diiferent from 

 A. horridum, Klf. in the deeply lobed forms. 

 Pantropical.

Bhizome creeping or ascending. Stipes 15 — 25 c.M. long, firm, erect, 

 dark-coloured, naked. Fronds lanceolate, acuminate, pinnate, 15 — 50 c.M. long, 

 the apex pinnatifid. Pinnae 10 — 30-jugate, subfalcate, short-slalked, 4 — T'/jC.M. 

 long, ± 1 — 1 '/i c.M. broad, acute or acuminate, the edge obliquely and broadly 

 serrate, the lower serratures sharply serrate or toothed, the higher sharp, simple 

 or 2-dentate, the upper base cuneale, sometimes ± auricled, tlie lower nar- 

 rowly cuneate in a curve. Texture + coriaceous, rachis firm, naked or slightly 

 villose, brown; veins oblique. Sori close, subparallel and nearly close to the 

 costa. 



Var. lepturuis: Pinnae longer, 9 — 12 '/j c.M. long, the edge deeply 

 serrate, rather lobed, the lower lobes or serratures sharply serrate, the apex 

 long-acuminate. 



Var. bipiiinatificliiiii: Lower pinnae pinnate at the base; pinnulae 

 nearly free, cuneato-rotundate, auricled, deeply toothed.

Bhizome and stipes? Fronds 50 — 90 c.M. long, elongate-oblong, pinnate, 

 the apex pinnatifid. Pinnae numerous, spreading, 10 — 15 c.M. long, linear, 

 short-stalked, acuminate, the edge broadly and shallowly crenate, but often 

 more deeply towards the apex, the serratures 2 — 4-dentate except the higher 

 ones, which are often entire and narrow, the upper base broadly and roundly, 

 the lower narrowly cuneate. Texture chartaceous; rachis naked or palea- 

 ceo-villose, dark-coloured; veins repeatedly forked. Sori oblique, subparallel and 

 nearly close to the costa. — Scarcely different from A. contiguum, Klf. except
