 most leaves slightly excurrent: capsule large, sub-oblong-cylindric, blood - 

 red, twice as long as pale coUum, pendent or patent, not appressed to 

 pedicel; peristome dark yellow or orange below, pale above; segments free, 

 very much shorter than membrane, cilia faintly appendiculate or rather 

 nodose; annulus broad; lid nearly flat and apiculate: dioicous. Mac.

312. Bryuiu percurrentinerve Kindb. — Tufts compact, dull green

 moistened sub-patent, crowded and slightly decurrent, ovate-obtusate, 

 only uppermost ovate oblong and sub-acute, narrow margined, revolute at 

 the entire borders for the greatest part; cells pellucid, upper wide, sub-
