at the base beneath. Texture subcoriaceous ; surfaces naked ; under surface 

 paler than the upper; veins 9—11 on a side, 2 — 3 higher simple, others 

 forked, with the anterior veinlet sometimes forked again. Sori crowded, 

 whether or not wanting in the upper part of the segments; indusium

(Sid) C sibuyanensis, CopeL, in Leafl., IV, 1150. 



Stipes 60 cm. long, brown-scaly at the base. Fronds to 180 cm. long, 

 the rachises short-hairy and densely scaly with minute, lacerate squamules 

 intermixed with linear, ciliate, caducous paleae, both leaving the rachises 

 roughish by their persistent bases. Pinnae petiolate, the central ones the 

 largest, to 35 cm. long and 18 cm. broad, abruptly acuminate. Lower pinnulae 

 short-stalked. Tertiary segments blunt or rounded at the apex, .the lower 

 cordate at the base, 12 mm. long and half as broad, petiolulate, cut down 

 nearly to the costa into suborbicular lobes, the following and those of the 

 higher pinnae somewhat longer, less deeply incised or subentire. Texture 

 coriaceous ; surfaces naked ; costae squamulose, or setulose in the upper part ; 

 veins once or twice forked. Sori submedial ; indusium globose, persistent.

Fronds 3-pinnate. Pinnae approximate, ascending, petiolate or the 

 higher sessile, 22 cm. long by 6—7 cm. broad. Pinnulae + 20 on a side, 

 subsessile, to 3'/j cm. long by nearly 1 cm. broad, bluntish, the lowest 

 a little abbreviated. Ultimate segments (leaflets, + 9 on a side, remote, 

 oblong or subcuneate, 4 mm. long by 2 mm. broad, obtuse, repando- 

 crenate, contracted and adnate at the base. Texture herbaceous; primary 

 and secondary rachises ochraceo-strigose above, scaly beneath, the scales 

 partly minute, adpressed, hair-like, partly longer, lanceolate, pale-fer- 

 rugineous, subentire or sparingly ciliate; tertiary rachises scaly, the scales 

 lanceolate, acuminate, whitish ; veins 5 + on a side, the higher simple, the 

 lower forked. Sori costular; indusium membranaceous, persistent, the
