178 DIPLOPERISTOML [Hypnum. 



The stems often exceed a span in length, and the leaves, in 

 certain situations, attain a greater size than in any British 

 species of Hypnum. 



43. H. striatum ; stems variously branched, leaves patent cordato- 



acuminate serrated striated their nerve reaching beyond the 

 middle, capsule oblongo-ovate cernuous, fruitstalks smooth, lid 

 rostrate. (TAB. XXVI.)

HAB. Woods and on shady banks, common. 

 This species comes near to H. rutabulum ; but is a larger and 

 more robust plant, with leaves more patent, broader, and more 

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

 fruitstalks are smooth, and the lid rostrate. 



44. H. confertum ; stems variously branched, leaves erecto-patent 



ovate acuminated concave serrated their nerve reaching half 

 way, capsule ovate cernuous, fruitstalk smooth, lid rostrate.

HAB. Trunks of trees, old rails, and on banks. 

 We have compared this with the Pennsylvanian H. serrula- 

 tum of Hedwig, and cannot even find the trifling difference 

 which Molir has noticed. A small variety, growing on trees, 

 has the leaves occasionally subsecund. 



B. Leaves squarrose. 



45. H. cuspidatum; leaves loosely set ovate concave nerveless
