HYPNACE^.] 163 [SUreodon. 



Perich. bracts erect, attenuated, entire, seta pale red ; capsule erect or 

 inclined, cylindric, ferruginous, lid with a long slender beak. 



HAB. Walls, rocks and tree trunks, not uncommon. Fr. 10 12. 



Mr. Beesley finds it very fine and frequent about Preston, Lanes. It is 

 rare on the continent, except in Jutland, and coasts of Holland and France. Its 

 chief distinction from cupressiformis lies in the direction of the leaves and their 

 symmetric form, as well as the rostrate lid, but the var. longirostris conies 

 very close ; it has however a distinctly different aspect. 



Var. /?. tenuis HOOK. 



Stems very slender, the leaves narrowly lanceolate, only slightly curved ; 

 capsules long and narrow, lid rostrate. 



SYN. Hypnum cupresstforme Var. tenue HOOK. Muse. Brit. 113 (1818) 

 HAB. Trunks and branches of trees. 



Frequent near Muckross Abbey, Killarney, and I have found it in fine 

 fruit, by the Orchy above Dalmally. Corresponds to var. filiforme of last 

 species.
