208 CONTRIBUTIONS TO THE FLORA OF BERWICKSHIRE. 



34. Peplis portula. In a pool, and by the side of a ditch, in Lang- 



struther Bog. 



35. JuNCUs coENOsus. In a marsh, within the sea-mark, between the 

 Cove shore and Dunglass burn, growing along with Glaux mari- 

 tima, &c. 



36. EuMEx CRISPUS. When the plant is littoral, as along the sea-shores 



of the parish of Cockburnspath, and in the chinks of greywacke 

 rocks near Redheugh, there is a large tubercle on each petal ; 

 while the plants growing on the sea-banks, and inland, have 

 generally only one perfect tubercle. 



37. Trientalis europ^a. About ten years ago there was a station 

 for this elegant plant on Penmanshiel Moor, but it has been 

 ploughed up. About two years ago, I found a small patch of it 

 on Ooldingham Moor, between Oldcambus Moss, and the Drone 

 Moss. This year I have found it in a very large patch, and 

 scattered in another place, under fir-trees in Blackburn-rigg 

 Wood. It also occurs on the boggy moor adjacent to the wood. 



38. Epilobium angustifolium. Exceedingly abundant on the sea- 



banks between Eedheugh and Dowlaw. 



39. Polygonum lapathifolium. Not uncommon near Penmanshiel, 



and Cockburnspath Tower. 



40. Adoxa moschatellina. In Sisterpath Dean, below Penmanshiel 



onstead : abundant by the side of the Pease burn, above and below 

 the forester's house. 



41. Pyrola MEDIA. Eed Clues Cleugh; Blackburn-rigg-dean; Birchy- 



bank, and Kitchen Cleugh. Also on the moors near Dowlaw, but 

 never in flower. This plant flowers in its greatest beauty under 

 long heather. 



42. Pyrola minor. In Blackburn-rigg Wood, perhaps introduced, 

 this being a wood of recent date. It abounds under fir-trees, in 

 the older parts of the wood, which have once been ploughed. In 

 the newer parts where it is rarer, it prefers a similar situation ; 

 being never found where the shade has not yet extirpated the 

 aboriginal plants (Calluna vulgaris, Erica cinerea, &c.) In 

 the newer parts of the wood the occurrence of Hieracium syl- 

 VATicuM is diminished or increased in dependence on similar 

 circumstances. 



43. Chrysosplenium alternifolium. Sisterpath Dean ; side of the 

 Pease burn, above the forester's house ; abundant in Blackburn- 

 rigg-dean. 



44. DiANTHUs deltoides. Sea-bank near the foot of Dunglass Dean. 



45. Arenaria verna. Sea-bank between Dowlaw and Eedheugh. 



46. Sedum villosum. Langstruther Bog ; Greenside Hill ; Pease 

 Bridge Woods. 



47. Lychnis diurna. A variety with a white flower occurs in Lums-
