C. integerrimus is a native of the Sierra Nevada of Cali- 
fornia and British Columbia, at elevations of two thousand to 
four thousand feet, from Washington to St. Bernardino and 
S.E. Arizona. It is one of the many discoveries of David 
Douglas in 1833, who collected a small-leaved variety, 
that occurs at various points of the range of the species. I 
found it when travelling with Dr. Gray, fruiting in Septem- 
ber, 1877, in Strawberry Hill Valley, near Mt. Shasta, and 
in the Wellingtonia Grove of Calaveras. It was intro- 
duced into this country by Mr. Robert Wrench, who gave 
seeds of it to the Royal Horticultural Society, in whose 
gardens it flowered in 1856, and was figured at the time 
by Lindley in the Gardeners’ Chronicle, cited above. It 
has been in cultivation in the Arboretum, Kew, for many 
years, growing in a sheltered position, and flowering freely 
in June. 
Descr.—An erect shrub, with very slender branches, 
young branches puberulous, quite glabrous in maturity.
