Fruct. Calyptra at first rqitriform, at length mostly 
dimidiate, whitish, scariose, tender, even, glabrous, very 
fugacious. Fruit-staTk terminal, mostly even (in one spe- 
cies rough), rigid, generally rather short, straight, some- 
times elongated, and subflexuose, yellowish or reddish. 
Apophysis when mature obconical, a Httle narrower than 
the theca, nearly the same colour, and smooth. Theca en- 
tire, ovate, about equal in length to the apophysis, even, 
shghtly contracted at the mouth, and without an elastic 
ring. Lid nearly of the same colour as the capsule, shortly 
conical, obtuse ; in some species, internally adnate with the 
columella, and remaining a considerable time. Pei'istome 
simple, of 32 primary, once geminating teeth ; which, when 
dry, are straiglit, more or less erect, never reflexed : these
