mutabile, T. crispum, and T.Jlavovirescens ; as well as Pottia crinita, 

 Desmatodon nervocus, and Grimmia rnaritima. 



55. H. UNDULATTJM, Dill. Upland woods and dry heaths ; 

 commou. It grows on several places on Cheviot, as at the top of 

 the Bizzle. " Muscus formosus— valde conspicuus." — Sir J. E. 

 Smith. 



56. H. DENTiCTJLATUM, Dill. On stonos, roots of trees, shady 

 banks, and on the ground in dark woods ; common. Abundant 

 in crevices of rocks in Henhole and the Bizzle. A broad-leaved, 

 upright, dark green, mountain variety grows in clear water in the 

 higher hollows of the Cheviots ; which in the structure of its 

 leaves resembles H. sylvaticum ; for which, according to Mr. 

 Wilson, it has often been mistaken. 



57. H. ELEGANS, Hooker. On shady banks at the roots of 

 trees, and in crevices of rocks. N. Above Langleyford, and in 

 Hepburn wood ; a very dwarf form in the Bizzle, near the burn. 

 B. On tree roots in the wood betwixt Drakemire and Brockholes. 

 — /. A. Near Abbey St. Bathans. — J. B. B. 



58. H. MULCEifs, Wils. MSS. This is a larger moss than 

 H. elegcm's, which it resembles in its shining foliage : the nervation 

 is variable. Mr. Wilson, considers it as apparently distinct, and 

 intermediate between H. elegans and II. depressum. In its 

 growth it is similar to H. denticidatum, but will be known from it 

 at once by its slenderness. I may be better able to trace its 

 peculiarities, after a further search for more examples. Gathered 

 in July, 1867, in a shady hollow at the base of a rock on the 

 west side of Henhole, not far from the entrance to the ravine. 



61. Omalia, Bridel. 



1 . 0. TRiCHOMANoiDEs, Dill. Among dry rocks and on trunks 

 of trees. E. Near Jedburgh. — A. J. B. In the dean between 

 Brockholes and Horsley. — Near Allanton. — Mr. Kelly. N. 

 Hetton burn.— W. B. B. 



62. Neckera, Hedw. 



1. N. COMPLANATA, L. On trunks of trees, and dry rocks. 

 It is not uncommon on the high sea-banks ; and rises to the 

 Bizzle and Henhole. 



2. N. CEisPA, Dill. Among dry rocks, which are moist in 

 winter, not common. N. "At the foot of Cheviot." — Winch. 

 Not re-found there. Among rocks on the north side of the Bizzle, 

 in one spot ; also in Henhole. B. Mr. Jerdon found it on the 

 sea-bank among rocks, at Earnsheugh, where the water of Cold- 

 ingham Loch runs to the sea, on the eastern side. I have 

 visited the spot since, and found it in considerable quantity. 

 Arenaria verna was growing amongst it. 



63. Eookeria, Smith. 



1. H. LUCENS, Dill. Moist banks, burnsides, and moss-pits, 

 and amongst moist mountain rocks ; generally distributed. N.
