HYPNUM. 101 



folk. Mr. Turner. Marshy ground between Copgrove and 

 the river Ure, Yorkshire. Rev. James Dalton. 



Dillenius did not know this fine moss as British. We are 

 indebted for the discovery of it to Mr. Dickson, and to Mr. 

 Dalton for specimens with perfect capsules. It approaches 

 very nearly to the last-mentioned species, but differs by its 

 larger size, more upright and pinnate mode of growth, 

 orange-brown colour, shorter lid, and longer capsule. 

 H. allicans ; leaves erecto-patent, ovato-lanceolate, acu- 

 minated, striated, entire, nerve reaching half way up; 

 capsules ovate, cernuous; fruitstalks smooth 5 lid conical.

 This plant is of a much paler colour than H. lutescens, 

 much less branched, and more upright in its growth : yet 

 we must confess that the characters of these two, of H . ni 

 tens and of H. salelrosum, approach so nearly to one an- 

 other as to render the discrimination between them a most 

 difficult task; nor should we be surprised to find that fu- 

 ture observations prove them to be varieties of the same 

 species produced by different circumstances of growth. 



* * Leaves serrated. 

 f Stems below lare of leaves. 



H. alopecurum; stems erect, below simple and naked, 

 fascicled above; leaves concave, ovate, elliptical, acute, 

 serrated, nerve running nearly to the point, margin reflexed; 

 capsule ovate, cernuous ; lid rostrate. (TAB. XXV.)

HAB. Woods and shaded banks, common. 



This and the following, which are amongst the largest of 

 our Hypna, resemble several species from New Holland in 

 their upright stems, almost naked below, and thickly fasci- 

 cled branches at the summit. A variety of our plant, grow- 

 ing in running water, departs from this appearance in being 

 branched from the very base, with the branches more elon- 

 gated, and having the leaves more closely set, and shorter. 



H. dendroides ; stems erect, below simple and naked, fas- 

 cicled above ; leaves ovate, often more or less lanceolate, 

 striated, serrated at the point, nerve reaching nearly to 

 the summit; capsule erect, ovato-cylindrical j lid rostrate,
