Earlston, &c. N. In the Bizzle. On a mountain-asli near Hart- 

 Lope Linn. This tree is remarkable as being the only one on 

 which I ever saw the leaves puckered by Psylla Sorhi ; on its 

 decayed trunk is also found the rare lichen Megalospora sangui- 

 iiaria. In Keller's "Lake Dwellings," it is recorded that one 

 of the mosses used by the pre-historic Helvetians for stopping 

 the holes in the walls of their huts, and also for bedding was this 

 species, pp. 342, 350. It is somewhat remarkable that, although 

 a scarce moss with us, I found it over-running a British hut 

 behind Humbleheugh. There is along winding band of it, from 

 bottom to top of a fissure, on the N.W. side of House of Crag. 

 Hazelton rigg wood, on an elm. On an ash tree, Hetton hall. —

 — Rev. A. Baird. It occurs at the bridge, but more frequently 

 by the burn side, a little farther up. N. " On rocks in Humble- 

 ton dean, above Wooler." — Dr. Johnston in "Winch's Flora. It

 wood and Old Melrose.

 confined to the northern or drier side.

 Helen's Church, Oldcambus, most apparent in winter, while 

 water trickles over it. Near Ayton. — W, S. N. On rocks, and 

 also on a tree on the north bank of the College at Heathpool

 sides of obstreperous, dashing burns, in dark, woody dells ; com- 

 mon. It occurs at Harthope and Linhope Linns. 



58. Climacium, Weh. and Mohr. 

 1. 0. DENDROiDEs, W. and M. On wet bogs, from the sea- 

 coast to the Cheviot moors. Some of the most luxuriant exam- 

 ples I ever saw, grow among the mosses where the Common 

 burn ris es. According to Humboldt there is a considerable pro- 

 portion of calcareous earth in this moss, and Hyp.JJrista-castren- 

 sis. (Sprengel's Introd., p. 14.)
