leaves, and other points. I do not see any essential difference in 

 the lid, which is sometimes as long in this as in the last species. 



3. T. abietinum, Br. fy Schimp. ; stem erect, simple or bi- 

 partite ; divisions simply pinnate ; leaves crowded, imbricated, 

 erecto-patent, subsecund, ovate, acuminate, deeply sulcate, 

 papillose; margin reflexed; nerve reaching almost to the tip; 

 sporangium cylindrical, slightly curved, subcernuous; lid 

 conical, acuminate. Hook, ty Wits, t. xxv. ; Eng. Bot. t. 2037 

 in part ; (Moug. Nest. n. 226.) 



On dry banks, especially in calcareous districts, sand-hills, 

 alpine rocks, etc. Bearing fruit, but rarely, in summer. 



Dioicous ; forming loose tufts, ochraceous below, yellowish 

 above. Stem erect or decumbent, simple or forked, pinnate, 

 clothed with abundant narrow lanceolate paraphylla ; branches 

 crowded, often flagelliform and drooping; leaves crowded, pa- 

 pillose at the back, sulcate ; nerve strong, vanishing below the 

 tip, channelled and rough at the back ; stem-leaves broadly 

 ovate, acuminate, deeply sulcate, toothed above; margin re- 

 curved; branch-leaves narrower, more even; cells small, 

 roundish; perichsetial leaves striate; fruitstalk 1 inch high; 

 sporangium oblong, curved, cernuous ; lid acuminate. 



Frequently when the stem is prostrate it throws out several 

 erect branches which are simply pinnate, like those of more 

 normal growth. The structure of the leaves in H. Blandovii is 

 so completely that of Hypnum, that I have left it in the neigh- 

 bourhood of H. splendens and other nearly allied species. 



12. PSEUDOLESKEA, Br. Schimp. 



Sporangium and peristome as in Hypnum t the intermediate 

 cilia sometimes abortive; leaves papillose; cells all more or 

 less quadrate. 



Closely allied to Hctcrocludium, but differing in the struc- 

 ture of the leaves.
