Autoicous ; .densely caespitose, rigid, rather glossy green, fuscous 



at base. Lowest leaves ovate acute, accrescent upward, comal erect, long 



ovato-lanc, very acute, serrate at apex, the margin reflexed below, nerve 



rather strong vanishing in the apex, or excurrent, upper cells narrow 



linear, slightly flexuose. Caps, horizontal, on a long reddish seta 



arcuate at top, with a long neck, clavato-pyriform, pale fuscous; lid 



acutely conic or subrostellate, red at base ; annulus compound ; peristome 



large, ferruginous ; processes of endostome very narrow, long as teeth,

This and the two following , species are very closely allied, and they 

 depend for their stability as species principally on the position of the male 

 reproductive organs. Whether this may be invariable or not may be open to 

 doubt, as we find in some other mosses it is not always reliable. 



2. POHLIA POLYMORPHA Hornsch. 



Paroicous ; laxly tufted. Comal leaves oblong-lanc, sharply 

 serrate at apex, nerve vanishing at point. Caps, from a shorter neck, 

 oval-oblong, horizontal, lid conic, muticous. Antheridia axillar.
