Flora of Berwickshire. 25 



bright-coloured Chrysomdce, which arc crawling about on 

 these plants. A variety of plants grow on both sides of 

 the river here besides those mentioned, especially on seams 

 of a red hue facing liutton Hall mill-dam. The cliffs 

 opposite Edrington Mill now claim our notice, displaying as 

 they do a good section of the subcarboniferous strata, with 

 the red selenite and white gypsum showing through the 

 shales. The beautiful moss Hypnum commiUatum, which 

 hangs in masses over the steep rocks, is here petrified by 

 the trickling of the water loaded with calcareous matter 

 percolating through them, eventually becoming as hard as 

 possible. Fine green-coloured masses of this Hypnum are 

 sometimes obtained, preserving the pectinated appearance 

 of the moss, which are very attractive as specimens for the 

 rock garden. For the same purpose, the red selenite and 

 white gypsum are much sought after. Whitehall is the 

 next part of the river bank we have to examine, which is 

 easily known by a wooded eminence 100 feet high, coming 

 sheer down to the river, named Steepleheugh, and well 

 known to artists for its picturesque beauty. Under the 

 planes at the Blue Stone ford, Viola odorata grows in pro- 

 fusion. In the woods Chelidonium majus. Arum macula- 

 turn, Vicia glycyphyUus {\\\ the sand pit), Narcissus Pseudo- 

 Narcissus, N. hijiorus, Galanthus nivalis., &c., are to 

 be found. This is an ancient place. The flowers of both 

 Narcissi growing in the turf assume a greenish tint. In 

 the pastures I have occasionally picked Orchis pyramidalis, 

 a true limestone plant. About Allanton, near a spring, 

 many good Carices are to be got, and Viola odorata, Lysi- 

 machia Nummularia, Ornithogaluvi nutans, &c., grow on 

 the lower part of the Blackadder banks. Blimtdus luteus 

 seems quite wild on all this section of tlie river up to 

 Prestonhaugh, where it growls broadcast. Arum macula- 

 turn in the Blanerne Woods, and Lathraa Squamaria at 

 Retreat Woods, must close my list for the j)resent of the 

 Whitadder flora. In the summer of 1882, in a dean 

 (Blackburn Rig) near Grant's House, on the North British 

 Railway, I picked Tricnfalis ciiropa^a, the only station I 

 know in the county fur it, and record it here. Fyrola 

 media and Polypodium Dryopteris, with Melica nutans, are 

 also, with much that is interesting, growing there also.
