nae much the largest, subdeltoid, unequal-sided, 7—10 c.M. broad. Pinnulae 

 lanceolate, imbricate, those at the lower base larger than the others, the low- 

 est deeply pinnatifid. Segments oblong, blunt, faintly toothed, the teeth 

 not awned. Texture subcoriaceous ; both surfaces naked; rachis and midribs 

 slightly fibrillose. Sori principally medial; indusium peltate or reniform.

Rhizome creeping, densely clothed with short, setiform or hair-like scales. 

 Stipes scattered, 30—70 c.M. long, fibrillose or scaly at least near the base. 

 Pronds 30—70 c.M. long, deltoid, 20—50 c.M. broad, with a long, pinnate 

 apex and below this ± 5 — 6 pinnate pinnae on each side. Lowest pinnae 

 - 2-pinnate to 3-pinnatifid at the base, the lower basal pinnulae the longest. 

 Leaflets subrhomboidal, the upper base ± truncate and auricled, the lower base 

 cuneate, the edges more or less lobed with the lobes copiously toothed, the 

 teeth aristate. Texture + coriaceous; surfaces naked; rachis nearly so. Sori 

 nearer the midrib than the edge; indusium peltate or reniform. 



War. Hamiltonii: Largest form; ultimate segments large, ovate- 

 deltoid, slightly lobed. — 



The rhizome of the type is figured in Bedd., Handb. Ind. Perns, fig.

Near P. aristatum, Pr., but the rhizome erect, the scales long, linear- 

 lanceolate. Stipes tufted, the base clothed with narrow, blackish scales. Pronds 

 large, 60 — 90 c.M. long, (30—50 c M. long, conf. Copel.), 4 — 3-pinnate. Ultimate 

 pinnules and segments small, less coriaceous, ovate or rhomboidal, aristate. 

 Sori large or small; indusium peltate, sometimes reniform. — The creeping 

 rhizome figured in the head of the mentioned table is that of P. ai-istatum, Pr.
