Woods and banks, among bushes, frequent. Fr. Oct. — Allied to H. 

 purum ; but slenderer, more rigid and more compressed in the stems and 

 branches, which are of a red colour, best seen by holding the plant be- 

 tween the eye and the light.

Wet rocks and in woods. Dargle and Powerscourt, near Dublin, Dr. 

 Taylor. Ben Lawers, Dr. Greville. Campsie hills, near Glasgow, Mr. 

 Arnott. Mill Dingle, near Beaumaris, and woods near Bangor, but al- 

 ways barren, Wilson. Fr. ? — This has probably not unfrequently 



been taken for Pterogoninm filiformc, and Mr. Mackay's specimens in E. 

 Bot. under the last-mentioned name, are H. catemdatum. The present 

 plant is a genuine Hypnum, having a single filiform process between the 

 segments of its inner peristome. The stems are closely tufted, from one 

 to two inches in length, rigid. Leaves rather remote, of a dark green 

 colour, their margins appearing as it were serrated from the papillae on 

 the surface. In our specimens, the nerve is short, not more than one 

 fourth of the length of the leaf, whilst in II. catenulatum of Schwaegr. 

 it is said to disappear beyond the middle.
