to a broadly winged rachis, the lobes incised again. Ultimate segments obtuse, 

 + 2 m.M. long, + 1 m.M. broad, with an acute sinus. Texture thin; veins 

 very conspicuous, 1 in each ultimate segment. Sori 6 — 8 to each frond, 

 placed on the lower lobes of the higher pinnae, 1 — 2 to a pinna, deeply 

 immersed; indusium lanceolato-cylindrical ; receptacle included.

 Rhizome filiform, wide-creeping. Stipes 1 — 1'/2 c.M. long, erect, distant, 



naked, not winged. Fronds ovate-rhomboidal, + o'/j — 4 c.M. long, 5-pinna- 

 titid. Lowest pinnae largest, deltoid, with the lower base cuneate-truncate. 

 Ultimate divisions linear, 3 — 5 m.M. long, ± 1 m.M. broad, 1-nerved, entire, 

 erecto-patent. Sori terminal, solitary; indusium infundibuliform, narrowly 

 winged on both sides nearly or quite to the top of the tube, the mouth 2- 

 lipped, the lips small, semi-orbicular; receptacle shortly exserted.

(36) T. gracile, r. u. s., Ned. Kruidk. Arch., V^ 1S7. 



Stipes filiform, 6 — 8 m.M. long. Fronds ± 3 c.M. long, 7 — 10 m.M. broad, 

 oblong or obovate, narrowed at the base, pinnate. Pinnae erect, distant, 

 the lower ones approximate, subopposite, oblong, subpinnatisect, plicate; the 

 segments recurvo-patulous, short, simply forked, with a blunt sinus, the lobes 

 narrow, emarginate at the apex. Wing of the rachis narrow, marginate. Sori 

 terminal on the ultimate segments, small, immersed; indusium short, ventricose, 

 the base narrowed, the mouth dilated, spreading, undulate. — Rhizome unknown, 

 perhaps creeping as in many of the species with small fronds.

Rhizome wide-creeping, rather filiform, tomentose. Stipes 2^2 — S c.M. 

 long, naked, or winged above. Fronds 2'/2 — 15 c.M long, 2^2 — 4V2 c-M. 

 broad, ovate-oblong or subflabellate, 3-pinnatifid ; main rachis narrowly winged. 

 Pinnae pimiatifid down to a narrowly winged rachis, the lower pinnulae 

 again deeply pinnatifid. Ultimate segments more or less numerous, linear, 

 often emarginate at the apex, whether or not purveyed with more or less 

 distinct spurious veins. Texture membranaceous; a central vein only in each ul- 

 timate segment. Sori 1 — 4 to a pinna, the tube more or less winged, the
