HAB. On trees and on banks, extremely common. 

 Jff. brevirostre, a name previously given by Ehrhart to a 

 variety of H. triquetrum, can never be applied to the present 

 species. 



41. H. velutinum; stems variously branched, leaves erecto-patent 



ovate often approaching to lanceolate acuminated serrated 

 striated their nerve reaching half way, capsule ovate cernuous, 

 fruitstalk rough, lid conical. (TAB. XXV.)

 HAB. Woods and hedgebanks, common. 

 The character here given will show how closely this species 

 is allied to the preceding ; and, indeed, except in its smaller 

 size, somewhat narrower leaves, and their more upright direc- 

 tion, we can find no point of distinction. So also is it with 

 the H. intricatum of authors, the specimens that we have seen 

 are smaller than our H. velutinum^ and the leaves even less 

 broad. Hedwig mentions a difference in the annulus, which we 

 have not been able to verify. 



42. H. ruscifolium ; stems variously branched, leaves loosely im- 

 bricated subpatent broadly ovate acute serrated concave their 

 nerve reaching nearly to the summit, capsule ovate cernuous, 

 lid rostrate. (TAB. XXVI.)
