pinnatifid again, but grows among the other, and seems only to be 
more luxuriant specimens. 
T. pusillum and T. muscoides are evidently very closely 
related, and may possibly, when known in growth, be passable as 
forms of one species ; but Kuhn considers our present plant 
distinct from the South American T. pusillum, Sw., and places it 
in another South American species, T. reptans, Mett., var. 
major, Mett.

Plate IV. Fig. 3. Nat. size. b pinnule and involucre, enlarged. 
Rhizome slender, branching, set with black shag. Frond one 
to four inches long, one inch broad, tripinnatifid, ovate-oblong, 
rounded at the point, and set on a slender wiry stalk, half-inch or 
more long. Rachis narrowly winged down to near the lowest 
pinnae. Pinnae longest at or above the middle of the frond, a half 
to three-quarter inch long, half inch broad at the base, cut in a 
pinnate or flabellate manner to the winged mid-rib, into narrow, 
linear, pinnatifid, dichotomous or forked membranaceous pinnules, 
having one vein in each segment. Margin not toothed. Sori 
terminal on the inner segments of the larger pinnae or axillary. 
Involucre cup-shaped, with a slightly expanded rim, generally 
more or less two lipped, not toothed. Receptacle central, often 
much longer than the involucre, but bearing capsules only on the 
lower part. 
In general appearance this is very much like Hymenophyllum 
Tunbridgense, from which it is distinguished by the involucre as
