Caudex and the short but copious, branching, fibrous roots 
quite velvety with black woolly hairs. Stipes scarcely 1 an inch 
long. Fronds 3 inches. Pinne rather distant, sometimes op- 
posite, very slightly decurrent. Rachis terete. Segments narrow. 
Inyolucres confined to three or four of the ultimate segments ; 
the mouth, with 2 rather distinct lips, very obtuse, but other- 
wise somewhat resembling those of 7. Filicula, Bory (T. bila- 
biatum, Nees), from which however in other respects the plant 
is evidently different.
