1858.] SCOTTISH BOTANY. 311 



34. Pyrola media. By the roadside, halfway between Castle- 

 ton and the linn of Corriemulzie. 



35. Pyrola rotundifolia. On many of the heaths, but I never ''■^ 

 saw it in bloom. 



36. Vaccinium uliginosum. The Sluggan, where I gathered -^ 

 one specimen with fruit ; also on several of the moors. As we 

 ascend the mountains, this plant quite takes the place of V. J 

 Myrtillus. 



37. Vaccinium Vitis-idaa. Common in all the woods and on ^ 

 all the moors. — I observed a curious fact with reference to this 

 plant, which I should like to hear confirmed or explained by the 

 observations of others : in July it was very unusual to find a 

 plant in flower — all were in berry ; at the end of August how- 

 ever it began to come into bloom again, apparently for the second 

 time in each plant. Is this a constant peculiarity of the plant 



in question ? i 



38. Arbutus Uva-ursi. Craig Choinnach, etc. ; very abundant 

 in the Sluggan, its purple stems and glossy-green leaves trailing 

 over the rocks, and studded in August with bright crimson ber- 

 ries ; frequent on the moors. . 



39. Veronica scutellata. Bog on the road to Glen Callater, -^ 

 near the village. 



40. Melampyrum sylvaticum. In some abundance at the linn 

 of Corriemulzie, the corolla of a very deep orange. / 



41. Galeopsis Tetrahit. Common in the cornfields. / 



42. Trientalis europceus. Among Ling and Heath to the north n/ 

 of the Sluggan ; also at the foot of rocks near Achallater. , 



43. Empetrum nigrum. Common on all the heaths. "''^ 



44. Polygonum vivipat^um. Equally common with the last. '^ 



45. Owyria reniformis. Stony banks of the Dee and Cluny, ■/ 

 abundant. 



46. Betula alba. A beautiful forest of Birch extends all the 

 way from Castleton to Corriemulzie. The pendulous variety oc- 

 curs at intervals, but less commonly here than in other parts of 

 Scotland, as in the Trosachs, for example, where it seems more 

 abundant than the other. ^ 



47. Betula nana. Very abundant on the boggy ground, sloping / 

 down to the Cuaich from the keeper's cottage at the head of the 

 Sluggan. / 



48. Salioo repent, yax.parvifolia. Not uncommon on the heaths, v/
