Bigelovia graveolens, as defined by A. Gray, is a very 
variable plant, of which he distinguishes five varieties, 
and he gives the height as 1 to 3 ft. Britton and Brown 
say 1 to 6 ft., and under cultivation, trained to a wall, 
grows considerably higher. At Kew it is grown against 
the wall at the north end of the Herbaceous ground, and 
it is pruned every season. At present the plant covers 
about 8 square yards, and it is very conspicuous when 
covered with its large clusters of bright yellow flower- 
heads. It has a wide range of distribution, extending 
from British Columbia to New Mexico, and it grows 
naturally in sterile and especially alkaline soils. Mr. W. 
Watson contributes the following notes :—‘‘ Kew is in- 
debted to the Rev. Canon Ellacombe for this shrub. He 
sent a small plant for identification in 1900, and it has 
now stood four winters without protection. Last year it 
was in full flower in mid-October, and so continued about 
a month. It might be called a shrubby Golden Kod, the 
big crowded corymbose clusters of yellow flowers being
