448 Mr. Hartly on the Moss Flora of the Eastern Borders, 



fuscescens, because the points of the leaves, under a high magnifier, 

 are minutely toothed. The same objection, however, applies to 

 the North American examples, which correspond in the minuto 

 denticulation, as well as in other particulars. Perhaps Schimper 

 by his " folia integerrima," means so only in comparison with 

 allied species. We scarcely expect a species of this section with- 

 out the points of the setulaa roughened. A much shorter moss, 

 straw-coloured, with green tips, arid more like fuscescens, grows on 

 the ridge of Cheviot, and on moist rocks in Het)hole, not so com- 

 pact or radiculose in the tufts ; and Mr. Wilson thinks it may not 

 be essentially different. When dried it does not become cjrky like 

 D. elongatum ; but can be separated readily. 



12. Leucobryum, Sampe. 

 1. L. GLATJCUM, Hampe. On heaths moderately moist, com* 

 mon. I did not observe it on the wet moors about Broadstruther ; 

 on Cheviot it occurs at the south-eastern end. 



13. Ceratodon, Bridel. 

 1. C. PUiiPURETJS, Bridel. On walls, tops of cottages, barren 

 woods, and bare places on moors ; common. On Cheviot it 

 appears in the barren soil at the top of the Bizzle ; and begins to 

 prevail on similar ground, as the bogs are left, in going above 

 Harthope Linn ; owing its elevation to this soil. 



14. Bicranodontium, Bmch and ScMmp. 



1. D. AEISTATUM, ScJiimper. (^Bryol. Enrop. Supplem.) Forma 

 foliis minus asperis brevioribus. E. Mr. Jerdon sent me this in 

 1864, saying that it was not uncommon on the Roxburghshire 

 heaths. Mr. Wilson refers it to this species, which, I believe, is 

 unrecorded for Britain. It grows also at Loch Skene. 



15. Campylopus, Bridel. 



1. C. DENsrs, Scldeich. Var. pragilis, Brid. N. In small 

 quantity, in moist places in Bizzle. 



2. C. TOEPACEUs, Brueh and Schimp. On peaty soil, on moors, 

 and in damp woods. B. Abundant at the edges of peat pits in 

 Penmanshiel moss ; Buncle woods. N. Cold Martin moss ; 

 Hebburn and Detchant woods ; moor above Broadstruther ; on 

 Cheviot near Belly side ravine, and also on the south-eastern end, 

 and at the top of the Bizzle ; Duumore, Ilderton Dod, and Hedge- 

 hope. 



3. C. PLEXTJOSus, Bill, and L. Swampy moors on a peaty 

 soil. N. In abundance in a peatery near the foot of Dunmore, 

 and of a smaller size on the adjacent moor. It occurs also in the 

 Bizzle, on Hedgehope, and near Alnwick. B. An obscure form 

 of it on the moor near Drakemire, in hollows where water stands 

 all the year. — J. A. In fruit in Penmanshiel moss. It grows 

 also in Buncle wood in a variety of forms and sizes. 



4. C. PARADOXUS, Nov. Sjj. Externally this resembles a
