distant, decurrent, the lowest sometimes forked. Sori round, or oblong and 

 parallel to the central ribs of the lobes, in 1 row on each side, quite im- 

 mersed in deep cavities, which form conical, truncate tubercles on the upper 

 surface.

Rhizome woody, wide-creeping, the scales dense, linear-lanceolate, acumi- 

 nate, ciliate, squarrose. Stipes distant, 10 — 50 c.x^I. long, firm, erect, naked. 

 Fronds deltoid-ovate, 20 — 50 c.M. each way, cut down nearly (to a naiTow 

 wing) to the costa into + 6 — 18 linear-lanceolate, acuminate lobes. Lobes to 

 25 c.M. long, 1 — 1 ^2 c.RI. broad, with the edge entire or crenulate to slightly 

 undulate, the lowest ones deflexed. Texture coriaceous; surfaces naked; main 

 veins prominent below, distinct and straight to the edge; areolae with free 

 veinlets. Sori in I row on each side of the costulae, nearer the costulae 

 than the edge, immersed, prominent on the upper surface,

Rhizome wide-creeping, the scales ovate-lanceolate, acuminate, peltate, 

 adpressed, deciduous. Stipes scattered, 7 — 50 c.M. long, firm, erect, naked, 

 glossy. Fronds varying from simple (oblong-lanceolate, 10 — 20 c.M. long, 

 entire or irregularly crenate or slightly lobed) to deeply pinnatifid (20-90 

 c.M. long, 15 — 60 c.M. broad) with 1 to numerous entire, erecto-patent lobes 

 on each side. Lateral lobes lanceolate-oblong to linear, similar to the ter- 

 minal one, 10 — 56 c.M. long, 1 — 4 c.M. broad, the apex acuminate, the bases 

 connected by a costal wing + '/2 — 1 c-^^^- broad, the sinuses ± rounded. 

 Texture + coriaceous; surfaces naked; no distinct main veins; costal areolae 

 of the fertile fronds large, 1-serial, secundary ones copious, fine, with free 

 veinlets. Sori large, shallowly immersed, round or oblong, placed in 1 — 2 

 regular or irregular rows in the smaller forms of the species, or scattered 

 irregularly in the larger.
