* (25) C leucopbaes, HassU., Journ. of Bot., VII, 323. 



Stipe and rachis ruuricate. Pinnae linear-lanceolate, ± 10 — 12 c.M. 

 broad at the base, short-stalked, the apex acuminate. Pinnulae linear-lanceolate, 

 acuminate, the lowest longest, + 1 — 1 '/j c.M. broad at the base, the edge 

 deeply pinnatifid. Lobes linear-oblong, acute, falcate, ± 1 '/j — 2 m.M. broad 

 at the base, the lowest ± free, the edge recurved, crenato-serrate towards 

 the point. Texture coriaceous; surfaces naked, the upper one nearly white 

 when dry; veins forked. Sori globose; indusium membranaceous, lucid, soon 

 breaking down irregularly, at length evanished.

 Stipes ± 45 c.M. long, angular, orange-brown, covered with small, fur- 



furaceous scales and strong, cylindric, glossy, blackisb-red prickles. Fronds 

 ± 65 c.M. long, ± 40 c.M. broad, deltoid; main rachis prickly. Pinnae 

 10 — 12, ± 20 c.M. long, + 8 c.M. broad, ovate, short-acuminate, sessile, 

 the apex pinnatifid, the lowest not shorter. Pinnulae 15 — 18 on each side, 

 sessile, linear-lanceolate, acute, pinnatiGd nearly to the costa. Lobes falcate, 

 deltoid, the edge entire, revolute. Texture coriaceous, firm but flexible; upper 

 surface naked or sparingly hairy, under surface opaque-glaucous ; veins covered 

 with subulate hairs and white, ovate-bullate scales. Sori small, nearer the 

 edge than the costulae; indusium afterwards flat and orbicular. 

 Celebes.

Stipes db 17 c.M. long, dark-brown, densely short-aculeolate, with few, 

 black-brown, lanceolate scales. Fronds large, 3-pinnatifid ; rachis tomentose 

 above, the base subasperous or muricate. Central pinnae elongate-lanceolate 

 to + 60 c.M. long, 12 — 15 c.M. broad; rachis densely tomentose above. 

 Pinnulae 2 — 2'/2 f-M. broad, elongate-oblong, acuminate, slightly narrowed 

 towards the base, sessile, the apex crenate, the edge deeply pinnatifid nearly 

 to the costa. Lobes compact, 4 — 5 m.M. broad, oblong, falcate, obtuse, entire 

 or rarely crenate. Texture subcoriaceous ; costa hirsute above, sparingly covered 

 beneath with minute, pale, bullate scales; veins + 9 on each side, oblique, 

 forked. Sori few, close to the costulae, occupying the lower 1 — 2 veins; indu- 

 sium thin, membranaceous, soon breaking down and falling away. iMettenius 

 describes the texture as membranaceous.
