Paroicous ; in lax irregular tufts closely resembling P. acuminata. 

 Leaves ovato-lanc, softer, shorter, upper cells shorter, less incrassate, 

 margin more distinctly serrate. Caps, from a shorter neck, oval-oblong, 

 brown, with a shorter orange muticous lid. Antheridia in pairs in the 

 axils of the upper bracts. 



Hab. — On rocks and turf in mountains ; not common. Fr. 7 — 8.

This moss appears to be intermediate between P. acuminata and elongata, 

 and agrees with the latter in the male infl., but the capsule is shorter 

 than that of either. Many varieties have been estabhshed, but I can only 

 recognise the two described as indigenous. 



3. POHLIA ELONGATA Hedw. 



Paroicous ; gregarious. Lovi^er leaves ovato-lanc, upper elongato- 

 lanc, erecto-patent, serrate at apex, nerve vanishing. Caps, elongate 

 elliptic, with a long neck, drooping, cilia of endostome none or rudi- 

 mentary. (T. LXVI, F.)
