VOL. xviii. (i) THE DISTRIBUTION OF CALLUNA 71 



here are very intricate, but the ground I refer to is in the 

 County of Gloucester, though it is on the border of Wolford 

 Wood, which is mainly in Warwickshire. Here Calluna vulgaris 

 is plentiful, and with it are the following plants of the Heath 

 association : — Erica Tetralix L., Ulex Gallii PJanch., Viola 

 canina L., Montia fontana L., Hydrocotyle vulgaris L., Galium 

 saxatile L., Salix repens L., Salix aurita L., Potamogeton poly- 

 gonifolius Pourr., J uncus squarrosus L., Carex binervis Sm., 

 Mollinia ccerulea Moench., Nardus stricta L., and the Mosses 

 Polytrichum commune L., Aulacomnium falustre Schwaeg., 

 Hypnum exannulatum Giimb., and Campylopus pyrijormis 

 Brid. 



The Northern Drift extends from Moreton down the 

 Evenlode Valley to Milton, in Oxfordshire, and on the Ord- 

 nance Map its course is marked by numerous Heaths. The 

 land now is mostly under cultivation, and so much' of the 

 former Heath vegetation is destroyed. It is probable that in 

 former days many of the plants mentioned above were found 

 along the course of the Northern Drift. Mr Druce, in the 

 Flora of Oxfordshire, records Calluna vulgaris from Bruern 

 Wood, and Lord Moreton mentions that a small patch of 

 Heather grew in a wood called Churchill Heath, near Kingham 

 Station, till within two or three years ago. Lord Moreton also 

 drew my attention to the name Bruern. The Abbey here was 

 also known as Bruere and Brueria (Dugdale's Monasticon), 

 perhaps from the Heather, French, " Bruyere." In " Place- 

 Names of Oxfordshire," by H. Alexander, another derivation 

 is suggested from the Old English breaw-ern, meaning brew- 

 house. 



The Cotteswold Hills, as defined by Mr Buckman in the 

 Proc. Cotteswold Nat. F.C., vol. xiv., include Wychwood 

 Forest in Oxfordshire, but not this country of the Northern 

 Drift. Mr Druce remarks in his Flora that the Oxford Clay 

 at Ramsden Heath in the Wychwood district is capped with a 

 gravel deposit, and on this are found several ericetal plants 

 including Calluna. Also in the springs where the gravel meets 

 the clay, Sphagnum is still found (1886). This is the only 

 record of Sphagnum on the Cottes wolds.
