Additions to the Muscology of the Border. By Archibald 

 Jerdon, Jedfoot Houses, Jedburgh. 



The following mosses, not enumerated by Dr. Johnston in 

 his *' Natural History of the Eastern Borders," have lately 

 been found by me in this district, and should, I think, be 

 recorded in our annals, particularly as the Club now extends 

 its Meetings to Roxburghshire. 



Sphagnum compactum. Common on wet moors, but generally 

 barren. 



Sphagnum molluscum. Not uncommon on wet moors. Fruits 

 in summer. 



Weissia cirrata. On the roof of a thatched cottage in Eoxburgh 

 village, in abundance. 



Dicranum majus. A good sized patch of this species was found 

 in Lintalee Grlen, but not in fruit. 



Didymodon ruhellus. I gathered a small patch of this among 

 stones by the side of the Jed last spring. 



Cmclidotus riparius, (3. terrcstris. A single patch of this species 

 on a stone by the side of a wet ditch, without fruit. 



Encalypta streptocarpa. Growing in some abundance on rocks 

 by the side of the Oxnam, near Craihng, but not in fruit.'^- 



Bryum crudum. In wet spots in woods and on hedge banks. 

 Not common. A beautiful moss, of a delicate pale glaucous 

 green. In fruit on a wet bank, in a wood by the Jed about 3 

 miles above Jedburgh. 



Bryum pallens. Wet places and springs on moors. Not im- 

 common. 



Bryum uliginosum. Wet places near rivers and in small ditches 

 on moors. Not uncommon, but generally barren. Very fine, 

 and in fruit on a wet face of rock near Old Cambus, Berwick- 

 shire. A large and fine sj)ecies. 



Mnium affine. Bogs, wet places in woods, &c. Not uncom- 

 mon, but seldom found in fruit. 



Leucodon sciuroides. A single patch on an elm tree by the side 

 of the Jed above Jedburgh. Barren. This moss, so common in 

 the south of England, is rare in Scotland. . 



Hypnum glareosum (Bruch.). On rocks by the banks of the 

 Oxnam, near Crailing. Eare, and not in fruit. 



Hypnum exannulatum (Griimb.). In wet ditches on moor be- 

 tween Jedburgh and Timpendean. Eare, and barren. This 

 moss was named for me by Mr. Wilson, the author of "Bryologia 

 Britannica." 



* I have had some difficulty in determining the two latter mosses, but, having 

 obtained the opinion of a good botanist, corroborating my own, I have no hesita- 

 tation in enumerating them in this list.
