Woods and hedge-banks, common. Fr. March — This is a species 

 very closely allied to the preceding, and indeed, except in its smaller 

 size, somewhat narrower leaves and their more upright direction, we can 

 find no point of distinction. — Mr. Wilson thinks it may be but a var. of 

 H. rutabulum. 



47. H. ruscifolium, Neck, (long-beaked water Feather -Moss); 

 stems variously branched, leaves loosely imbricated subpatent 

 broadly acute serrated concave, the nerve reaching nearly to 

 the summit, capsule ovate cernuous, lid rostrate. Neck. Meth.

Upon wood and stones, in ponds and rivers. Fr. Oct. — The stems 

 often exceed a span in length, and the leaves/m certain situations, attain a 

 greater size than those of any other British species of this genus. 



48. H. striatum, Schreb. (common striated Feather- Moss); 

 stems variously branched, leaves patent cordate-acuminate ser- 

 rated striated, the nerve reaching- beyond the middle, capsule 

 oblongo-ovate cernuous, seta smooth, lid rostrate. Schreb. II.

Wood- and Bhadj banks, common. Fr. Nov. — Allied to //. rutahu- 



lum ; but a larger and more robust plant, with leaves more patent, broader 



and more decidedly striated, with a shorter point and longer nerve ; the 



seke are smooth and the lid rostrate. — A pretty small var. is found bj 

 Mr. Wilson, growing at Mucruss, Ireland, together with H. crau 

 riiiin, often bearing 2 s, i,r from the same perichsetium.
