Ascends to 1050 yards, in the East Highlands. 



Range of mean annual temperature 49 — 37. 



Native. Uliginal, &c. In damp or wet and shaded places, 

 frequently along with the other species, though much less 

 common, especially towards both the lower and the upper 

 limits ; indeed, this is quite rare on the mountains, where 

 C. oppositifolium is abundant. It is remarkable that all 

 the most southern counties indicated for this species, 

 should have been reported on authority scarcely sufficient 

 for reliance, without fi'esh confinnation, which has not been 

 made in our time. Still, though the question is attached, 

 in the line which indicates the South limits, those counties 

 are not so milikely as to justify their rejection, from the 

 range of latitude, &c. For Somerset and Surrey, we have 

 good and recent authoiities. T}^e of distribution inter- 

 mediate between Scottish and British.
