 HAB. Banks and wet bogs, generally mixed with other 

 mosses. Abundant on the Breadalbane mountains. 

 In fructification in marshy places near Forfar, Scotland. 

 Mr. Drummond. 



The slender habit, pale colour, and obtuse leaves, are strik- 

 ing characters in this species. It is incorrectly described in Fl. 

 Brit, and in JEngl. Hot. as having the leaves destitute of a 

 nerve. The fructification is rare. Besides the spot mentioned 

 above, we have seen it in that state near Dublin, with the lower 

 part of the fruitstalks buried for near two inches in a firm 

 sand bank, so that it was scarcely possible to secure good 

 specimens. 



16. H. trifarium; leaves compactly imbricated ovate obtuse en- 



tire concave the nerve disappearing above the middle, capsule 

 oblongo-ovate cernuous, lid conical. (TAB. IV.)

HAB. Upon a high mountain, on the ground, at the head 

 of Glen Lochy in Breadalbane; but without fruit. 

 Drs. Greville and Hooker. 



This is a dark lurid brown colour, with broader, more con- 

 cave, and more closely imbricated leaves, which, we think,' will 

 sufficiently distinguish it from H. stramineum. Our plants 

 exactly accord with Norwegian and Lapland ones. 



17. H.murale; leaves nearly erect imbricated oval with a very 



short point concave the entire nerve reaching about half way 

 up, capsule ovate cernuous, lid rostrate. (TAB. XXIV.)
