HYPNUM. 95 



Mohr appears to us rightly to have united the Hypnum 

 implexum of Swartz and Turner to the Hedwigian H. po- 

 puleum. H. Starkii of Schleicher's Catalogue-, if we may 

 judge from specimens sent by that botanist to Mr. Turner, 

 differs in no particular from our plant ; while Mohr describes 

 his species under that name as having a cordate base to the 

 leaves, and an evanescent nerve. 



0. H. reflexum ; leaves cordato-acuminate, serrated, their 

 nerve reaching to the point, their margin slightly reflexed ; 

 capsule ovate, cernuous; fruitstalks rough 5 lid conical.

HA.B. On Ben Nevis, near the base of the mountain. 



We have compared our plants with those of the original 

 discoverer, Mr. Starke, and find them to agree in every 

 particular. Its habit is very different from that of the pre- 

 ceding ; it is more straggling in its mode of growth, and 

 the leaves are broader and shorter, especially those of the 

 main stem, which are widely cordate with a suddenly acu- 

 minated point. 



b. Nerve shorter than the leaf, or none. 



* Leaves entire. 

 f Leaves ovate or elliptical. 



H. molle ; leaves loosely imbricated, rotundato-ovate, ob- 

 tuse, concave, entire, faintly two-nerved at the base, or with 

 one short nerve; capsule ovate, cernuous; lid conical.

HAB. Alpine rivulets in Scotland. 



This plant, usually, is found from two to three inches in 

 length, much tufted, and consequently with 4he branches 

 often erect, and bare of leaves at the base. Leaves of a 

 thin membranaceous texture, very dark lurid green colour, 

 concave, varying in the nerve, which is either single or 

 double. Swartz's plant (H. alpestre) is certainly of a more 

 rigid texture, the leaves are more patent, and the nerve is 

 more evident in general, the colour is yellower at the extre- 

 mities of the branches ; yet we cannot look upon it other- 

 wise than as the same species : and Mohr's H. trifarium,
