With all its Bl ui this may generally be recognized fairly 
easily by the robust habit, the large, cochleariform, widely and very 
shorily pointed leaves, rather less regularly arranged than in C

characterized by a short, stout seta, cpidderably less than a centi- 
metre in length, and I have a plant ie the capsules searcely 
elevated above the perichaetia; but the seta may be a full centimetre 
long. The rigidly divergent, i Hchaetal ena with short and wide
