Mr. R. Spruce on the Musci and Hepaticse of Teesdale. 197 



8. Aulacomnion androgynum, Schwsegr. (Bryum androgynum, 

 Hedw. ; H. and T.) Shaded rocks below the High Force, with gemmse. 



9. Barbula fallax, Hedw. (Tortula fallax, H. and T.) By the 

 Tees' side. 



10. E. muralis, Timm. Walls. 



11. B. ruralis, Hedw. Walls, &c. between Middleton and Bar* 

 nard Castle. 



12. B. suhulata, Brid. Banks and rocks, both in the high and 

 low grounds. 



13. B. tortuosa, W. and M. Frequent on limestone rocks. A 

 small var. occurs on the sugar limestone near the summit of Cronk- 

 ley Fell, which forms low spreading patches of a brownish hue ; the 

 leaves are shorter than in the ordinary form, their nerve less broad 

 and strong, and the capsules are always curved. 



14. 5. unguiculata, Hedw. Common. 



15. B. vinealis, livid. " Csespitosa, dioica; foliis recurvo-paten- 

 tibus, ovato- et elongato-lanceolatis ; capsula ovato-oblonga vel 

 oblongo-cylindrica, erecta, annulata, brevirostra ; peristomii 

 membrana conjunctiva longiore, dentibus semel contortis." — 

 Bryol. Eur op. 



B. vinealis, Brid. Bryol. Univ. i. Suppl. p. 830. 



On a wall by the road leading from Barnard Castle to Lartington, 

 with capsules just coming to maturity, June 23rd. It grows inter- 

 mixed with Weissia curvirostra, and the reddish stems are so much 

 alike in both, that a casual observer would hardly distinguish them. 



B. vinealis is very closely allied to B. fallax, but differs from 

 it as follows. Leaves longer and narrower, spreading and some- 

 what recurved (but not squarrose), with nearly plane margins ; 

 the inner perichsetial leaves scarcely differing from the rest_, but 

 in B. fallax much broader in their lower half and loosely sheath- 

 ing the pedicel : capsule annulate : operculum shorter : peristome 

 only once (in B. fallax three or four times) twisted. Besides, as 

 Bruch and Schimper observe, " les fruits murissent en ete, epoque 

 a laquelle ceux de B. fallax sont passes depuis longtemps.^^ At 

 the time I now write (Nov. 9th) the capsules oiB. fallax are just 

 beginning to ripen. 



I cannot account myself the discoverer of this moss in Britain, 

 for Mr. Wilson has lately sent me specimens gathered by him- 

 self at Nant-y-Belan, near Wrexham, in 1833 ; and he suggests 

 that even the Zygotrichia cylindrnca described by Dr. Taylor in 

 the ^ Flora Hibernica ' may be the same species. 



16. Bartramia arcuata, Brid. Heathy and rocky situations, abun- 

 dant, but I did not succeed in finding capsules. 



17. B. calcarea, Br. and Sch. " Procera, foliis secundis vel sub- 

 secundis, confertis, longioribus, crassicostatis, laxius reticulatis ; 

 perigonialibus omnibus acute acuminatis, solidi-costatis ; peri- 

 stomii minoris dentibus remote articulatis." — Bryol. Europ. 



Moist springy places, frequent, both on the limestone and basalt.
