 differing especially in the reddish color of the more divided 

 shorter stems, the shorter leaves with more compact areolation, 

 the perigonial broader and ovate-lanceolate, and the perichaetial 

 distinctly serrate, the capsule longer, with the pedicel erect at 

 base, and the annulus not revoluble but remaining attached to 

 the lid. — JBryum pulchellam^ Hedw. Muse. Frond, iii. 96, t. 38 ;

17. W. Tozeri, Schimp. 1. c. Plants small, loosely cespi- 

 tose, pale gi'een, soft, mostly simple : lower leaves distant, obo-

 discoid ; external perigonial leaves broad and concave at base, 

 open and lanceolate above, the inner gradually smaller, bearing
