Rhizome creeping, minutely scaly or fibrillose. Stipes 2-seriate, ± distant 

 or approximate, adherent to the rhizome. Fronds vai'iously divided; leaflets 

 narrow, linear-lanceolate or divided into narrow, oblong or linear segments; 

 veins free, simple or forked. Diels, in Engl. & Prantl, Nat. Pfl.Fam., I*, fig. 

 116, J & H. {Wib'elia).

a. Fronds at best 2-pinnale. 



b. Fronds small, under iO c.M. long. (1) T. oligophlebium. 



h.h. Fronds larger, more than dO c.M. long. 



c. Pinnae slightly erenate or toothed. (2) T. pinnatum. 



c.c. Pinnae deeply toothed, pinnatifid or pinnate. (3) T. gracile.

Rhizome slender, short-creeping, the scales minute, adpressed, linear, 

 brown. Stipes slender, naked, deeiduously scaly near the base, + I'/a — 7'/i 

 c.M. long. Fronds triangular, ± 5 — V'/j cM. long, 4 — 9 c.M. broad at the 

 base, pinnate, the lower pinnae ± spreading, pinnate again, + 2 c.M. broad 

 at the base. Ultimate segments oblong to linear, 5 — 20 m.M. long, 1 '/a — S'/i 

 m.M. broad, the base cuneate, the edge, erenate or bluntly toothed to lobed, 

 the point narrowed, bluntish. Textm-e subcoriaceous ; rachis and surfaces 

 naked; veins 1 to each tooth or lobe. Sori terminal on the crenations, 1 to 

 each; indusium firm naked, suborbicular, small. — The description is taken 

 from specimens gathered by Hallier, determined by Christ. — Baker's des- 

 cription: "Fronds pmna/e, 5*/, — 5 c.M. long, 8 — 9 m.M. broad, with the pin- 

 nae rhomboid, obtuse, 3-lobed," is probably taken from a young specimen.
