Ledum glandulosum has an extensive range in the 

 Sierra Nevada and Rocky Mountains of Western North 

 America, from Tulare County, California, lat. 36° N., where 

 it attains an elevation of 8-9000 ft. to 51" N. in the Rocky 

 Mts , where it was found by M. Macoun at 6000 ft. eleva- 

 tion.' How much further north it extends is not known, 

 but it advances southwards along that range to Colorado. 

 I collected it in fruit, in company with Dr. Gray, in the 

 Silver Mfc. Pass of the Sierra Nevada (California) in 1877. 

 Though first made known by Nuttall, who found it in the 

 Rocky Mts., it was discovered in about 1826 by Douglas, 

 from whom there is a (flowerless) specimen in the Kew 

 Herbarium, collected " at the confluence of the Columbia 

 River, towards Puget's Sound." 



The plant at the Royal Gardens, Kew, from which the 

 accompanying figure was made, was raised from seeds 

 received in 1894 from Professor Sargent (the Arnold 

 Arboretum), which flowered in the Arboretum of Kew in 

 May, 1897.
