(256) Pt. parviloba, Christ, Bull. Sci. Fr. & Belg., XXVIII, 264, 

 tab. XII. 



Near Pt. quadriaurita, Re(z, but small. Stipes slender, rufo-stramineous, 

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

 deflexed. 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 and size resembling 

 Pt. Grevilleana, ^^'aU. 



Luzon, Palawan. 



(256') Pt. caesia, Copel., Philipp. Journ., I, Suppl., 156. 



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

 puberulous like the racbis, 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 '/2 ^M. broad, entire, obtuse, 

 subauriculate, ± overlapping at the base, the sinuses closed. Texture papyraceous; 

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

 Sori narrow. — ■ Near Pt. quadriaurita, Relz, distinct enough to constitute a 

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



Mindanao. 



(26) Pt. amoena, J»l., 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; racbis 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, JBfe., Journ. of Bot., XXVI, 524. 



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

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

 nale to the I'achis, free or sometimes slightly joined, + 2 — 5 m.M. broad.
