Dioicous ; loosely tufted, ascending, glossy, bright green above, 

 pale fuscous below. Stems 2 10 in. high, coated nearly to apex with 

 dense pale rufous tomentum ; branches few, dichotomous. Stem leaves 

 squarroso-patulous, the terminal erect, falcato-secund, from a broad 

 oblong base, narrowly lineal-lane., more or less plicate, strongly undulate 

 transversely, complicato-concave, the margin revolute below, coarsely 

 and sharply serrate above, nerve narrow, flattened, vanishing in the 

 attenuated apex, bilamellate at back, the upper f with two divergent 

 rows of coarse teeth ; the basal angular cells large, orange, quadrato- 

 hexagonal, upper linear, narrow, elongated. Perich. bracts very broad, 

 convolute in a lax cylinder, prolonged into a ligulate flexuose subula, 

 coarsely serrate above, the nerve obsolete. Caps, on a pale red seta, 

 2 6 aggregated in one perichaetium, oblongo-cylindric, arcuate, lid 

 long as caps, conic with a long pale subulate beak ; annulus simple, 

 teeth large, deep red. Male gemmaceous, nestling in the tomentum.
