forked. Ultimate segments approximate, linear, VL_ — 5 m.M. broad, obtuse, 

 serrulate, the terminal one narrowed, the fertile ones hardly contracted. Tex- 

 ture papyraceous; veins conspicuous, albo-setaceous above; the rest naked. 

 Sori not reaching the apex of the segments. — Probably a local derivative , 

 of Pt. quadriaurita, Retz (Copel.).

Stipes erect, naked, 60 — 90 c.M. long, yellowish-green, rarely brown. 

 Fronds 30—90 c.M. long, 30—45 c.M. broad, the terminal pinna to 30 c.M. 

 long, 5 — 8 c.M. broad, regularly pectinato-pinnatifid with numerous nearly 

 spreading or falcate, entire, crenate or serrate, blunt, linear, close or + 

 remote lobes on each side, which are to 5 c.M. long and reach down nearly 

 to the costa, the terminal lobe ± caudiform. Lateral pinnae several on each 

 side, similar to the terminal one, the lowest + 5 c.M. apart, whether or 

 not forked at the base. Texture subcoriaceous ; rachis and both surfaces 

 naked; costae not rarely spinulose above; veins once forked. Sori reaching 

 nearly to the apex of the segments. — Hardly different from Pt. quadriaurita, 

 Belz, but the stalks of the pinnae + shortly winged by the decurrent bases 

 of the lowest lobes, the lowest anterior lobe generally shorter than the 

 opposite posterior one.
