Wet places, particularly in a calcareous soil. Fr. May. — Though 

 often confounded with //. filicinum, this may he distinguished by its 

 larger size, much less rigid stems and leaves, and its paler green colour. 

 The leaves, too, for want of the excurrent rigid nerve, are disposed to 

 be more curved and to become twisted when dry. 



B. Leaves destitute of a nerve, or furnished with two very 

 indistinct ones at the base.

Bogs, common. Fr. March. — This, which may rank among the 

 largest of the British mosses, is at once distinguished from its affinities 

 by its broad and nerveless leaves. In habit, it is allied to H. aduncum. 



69. H. Silesidnum, Beauv. (Sifesia?i Feather-Moss); leaves 

 loosely imbricated secund narrow lanceolate acuminate serrat- 

 ed nerveless or very obscurely 2-nerved at the base, capsule

On soil, in the clefts of rocks, mountains of Scotland, frequent, Fr. 

 May. — Allied to //. cupressiforme t but much smaller, of more straggling 

 growth, with more Berated, narrower and le>s falcate leaves, and a shorter 

 lid to the capsule. In some respects, it approaches //. pulchellum. 

 Frequently, the serratures occupy the whole margin from the bast 

 the extremity.
