[Dicranum. 



erect capsules, and pale calyptra, as well as by the leaves on the lower 

 part of the stems being adpressed not falcate ; the leaves are shorter 

 and less evidently serrulate. 



15. D. undulatum, EHRHART. Steins elongated ; leaves 

 nearly plane, lanceolate elongato-acuminate, serrulate at the 

 points, transversely undulate; capsule cylindraceous, cernuous; 

 lid with a long beak. Ehrh. Crypt, (according to Mohr.) Muse. 

 Brit.ed. 2. p. 100,*. 18. 



Near Bantry, Miss Hutchins. At Dunkerron, and woods at Kil- 

 larney. 



16. D. scoparium, HEDW. Stems elongated ; leaves narrow, 

 subulate, canaliculate, secund; capsule cylindraceous, arched, 

 cernuous ; lid with a long beak. Hedw. Sp. Muse. p. 126. Muse. 

 Brit.ed. 2, p. 101, *. 18. 



In, and in the vicinity of, woods ; common. Sometimes the peri- 

 choetium is very remarkably large, containing from 1 to 4 setce. The 

 calyptra of the yet unformed capsule dusky ; the capsules themselves 

 turning dark brown, or quite black. It varies very much in size and 

 length of the leaves and degree of crispation of the leaves when dry. 

 In the variety with black capsules a struma may be observed at their 

 bases. 



17. D. varium, HEDW. Stems short ; leaves narrow, hastato- 

 lanceolate ; capsule ovate ; lid rostrate. Hedw. St. Cr. v. 2, t. 

 34. Muse. Brit. ed. 2, p. 102, t. 17. 



On moist banks and fallow fields ; common. This varies by the 

 colour of its leaves, which are sometimes reddish and even lurid, their 

 direction, which is sometimes secund, and the degree of inclination or 

 position of the capsule on the setce. 



18. D. heteromallum, HEDW. Leaves subulate, falcato-secund, 

 nearly entire; capsule ovate, cernuous; lid with a long beak. 

 Hedw. St. Cr. v. 1, t. 26. Muse. Brit. ed. 2, p. 103, t. 18. 



On moist banks ; common. At Aooreagh River, near Sneem, I 

 have observed a considerable extent of the bank covered with this 

 species having the pedicells so flexuose and bent, that I know not how 

 that state is to be distinguished from D. cygneum of Hedwig. 



19. D. subulatum, HEDW. Leaves from a broad sheathing 

 base subulato-setaceous, secund, entire ; capsule ovate, subcer- 

 nuous; lid with a long beak. Hedw. Sp. Muse. t. 34. Muse. 

 Brit. ed. 2, p. 103, t. 18. 



Sides of Maryburn rivulet : Mr. Templeton. 



20. D. fulvellum, SMITH. Stems tufted ; leaves subulato- 

 setaceous, somewhat secund, entire, those of the perichcetium 

 convolute ; setae scarcely longer than the leaves ; capsule erect, 

 turbinate, furrowed when old ; lid conico-rostrate. Sm. Flor. 

 Brit. p. 1209. Muse. Brit.ed. 2, p. 103. Supp. t. 3. 



On Macgillicuddy's Reeks. This is altogether an alpine species, 

 and has the strongest analogy with Weissia acuta, the teeth of th^ 

 peristome being ofteft simply perforate, more rarely entire.
