 tah. XIV; T. digitatum, Sw., var. palmatifidum, Hk. Bk., Syn. Fil., 76. 



Rhizome slender, creeping, branched, intricate. Stipes scattered, capillary, 

 pubescent, 1 — 3 c.M. long. Fronds 1 — I'/j c.M. long, 1 — 2 c.M. broad, digitato- 

 dichotomous, the base cuneate or rounded. Ultimate segments linear, very 

 unequal in length, I'/j — 2 m.M. broad, the apex rounded, obtuse, retuse, the 

 margin minutely denticulate, each projection purveyed with a group of short, 

 flexuose ciliae. Texture thin, hyaline; veins 1 in each segment, «ilia!te, nearly 

 reaching the apex of the segments. Sori terminal on the segments; indusium 

 sunk, obconical or cupuliform, the surface and the margin ciliate.

Rhizome creeping, branched, intricate, hairy. Stipes filiform, villose at 

 least at the base, 5 — 20 m.M. long. Fronds and frondiculae conform, roundish 

 in general outline, to + 1 c.M. each way, subtruncate to cordate at the 

 base, palmatifid into many linear segments + */j m.M. broad. Segments simple 

 or 1 — 2 X forked, the ultimate lobes to 4 m.M. long, the apex blunt, rounded 

 or slightly emarginate; the medial segments often elongate and subpinnatifid. 

 Te*ture membranaceous, diaphanous. Sori terminal and solitary on the lobes; 

 indusium sunk, funnel-shaped, but the mouth not very much dilated.
