(256) Pt. parvilofoa, Chfist, Bull. Sci. Pr. & Belg., XXVIII, 264, 

 tab: XII. 



Near Pt. quadriaurita, Retz, but small. Stipes slender, rufo-stramineous, 

 scaberulous. Fronds broadly deltoid, the lowest pinnae produced, sharply 

 deflBxed. Ultimate segments close, linear-oblong, short, rather free. Texture 

 rigidly papyraceous; colour pale-ochraceous-green ; upper surface often rough 

 with rigid setae ; veins distinct beneath. Sori and indusia generally very 

 slender. — This form is often found strongly reduced [in size and iresembling 

 Pt. Grevilleana, V['all. 



Luzon, Palawan. 



(25(;) I*t. caeisia, Copel., Philipp. Journ., I, Suppl., 186. 



Rhizome short, erect. Stipes tufted, stramineous or brownish, slightly 

 puberulous like the rachis, the base densely clothed with fuscous, filiform 

 scales. Fronds 20—35 c.M. long, 10—18 c.M. broad. Pinnae + 1 c.M. 

 broad, cut down nearly or quite to the costa, the terminal one the longest, 

 the basal ones forked. Ultimate segments + 1 % m.M. broad, entire, obtuse, 

 subauriculate, + overlapping at the base, the sinuses plosed. Texture papyraceous; 

 upper surface bluish, spinulose on the costae and veins, under one pale-green. 

 Sori narrow. — • Near Pt. quadriaurita, Retz, distinct enough to constitute a 

 species. Christ points out that this species is near Pt. furcans, Bk. (Copel.). 



(26) Pt. amoena, m., Enum., 210; Hk. Bk., Syn. Fil., 479. 



Stipes naked. Fronds 2-pinnatifid. Pinnae opposite, short-stalked, lan- 

 ceolate, narrowed at both ends, pinnatifid, the lowest ones 2-partite. Segments 

 subfalcate-oblong, somewhat acute, the lower ones obtuse, the edges appresso- 

 serrate. Texture membranaceous; rachis and surfaces naked. — Baker con- 

 siders this plant to be a form of Pt. semipinnata, L. See the information 

 in Hk., Spec. Fil., II, 205. 



Java. 



• (27) Pt. furcans, nu., Journ. of Bot., XXVI, 324. 



Stipes naked, slender, blackish-purple or castaneous, glossy, 12 — 30 c.M. 

 long. Fronds 15 — ^20 c.M. long. Pinnae erecto-patent, lanceolate, simply pin- 

 nate, 2— 2Yj c.M. broad, lowest largest, + 15 c.M. long, forked at the base 

 in the fully developed, plants. 1 Ultimate segments linear, entire j obtuse, ad- 

 nata to the rachis, free or sometimes slightly joined, + 2 — 5 m.M. broad.
