(11) H. neogniiieeiljSis, C. Chf., Ind. Fil.; Davallia bipimiatifida. 

 Bk., Kew Bull, i899, 119. 



Rhizome slender, wide-creeping, the scales lanceolate, adpressed, mem- 

 branaceous, pale-brown. Stipes slender, naked, 7 — 10 c.lVI. long. Fronds 

 lanceolate-deltoid, 2 pinnatifid, 12 — 15 c.M. long, + 5 c.M. broad. Pinnae 

 sessile, the lower largest, the barren ones oblong, obtuse, slightly pinnatifid, 

 cuneate at the base, the fertile ones narrower, deeply pimiatifid, with the 

 lobes erecto-patent, the lower lobes oblong, obtuse. Texture coriaceous; sur- 

 faces naked like the slender rachis; veins flabellate, conspicuous. Sori solitary 

 OD the higher lobes, 2 — 3 on the lower ones; indusium semiorbicular, firm. 



New Guinea. 



* (12) H. alpina, Moore (not Sm.), Diels, in Engl. & Prantl, Nat. 

 Pfl.Fam., I', 209; H. repens, Diels, var., C. Chr., Ind. Fil; Davallia alpina, BL, 

 Rac, Flor. Btz., I, 127; — var. monlana. 



Like H. repens, Diels, but dimorphous. Stipes 1 — 10 c.M. long. Fronds 

 4 — 10 c.M. long, 3 — 9 c.M. broad. Barren fronds with the central pinnae 

 oblong, crenate, toothed or obliquely pinnatifid and the lower pinnae pinnate 

 or 2-pinnatifid.' Fertile fronds brown when dry, the central pinnae linear, 

 simple and the lower pinnae pinnate, the laciniae slightly narrowed, the edges 

 toothed, the teeth commonly sharp, upcurved. Sori occupying the upper 

 base of the teeth. 



War. niontana: Fertile fronds more finely divided, blackish when 

 dry, the laciniae much contracted so that the leafy membrane is nearly 

 wanting. Sori occupying the base of the always very sharp, hamate teeth.

Rhizome wide-creeping, scaly. Stipes 5— 12»/j c.M. long, scaly below. 

 Fronds 6—20 c.M. long, 5— IS'/^ c.M. broad, deltoid in outline, dimorphous, 

 the barren ones with' a narrowly winged rachis. Lowest pinnae cut down 

 nearly to the rachis with deep, bluntly toothed segments. Fertile pinnae more 

 finely divided; pinnulae of the lower pinnae cut down to a narrow rachis 

 into narrow, sharply toothed segments. Sori in the sinuses of the teeth.
