Few shrubs are more satisfactory in the garden than the 
members of the genus Philadelphus. They are easily grown 
and they flower profusely at a time when the great majority 
of flowering trees and shrubs have gone out of blossom. 
The one now figured is attractive not only for its abundant 
clusters of white, well-formed flowers, but for its agreeable 
fragrance. P. Delavayi was first introduced into European 
gardens by the Abbé Delavay, who sent seeds from Yunnan in 
1890. It was again met with in 1904 by Mr. E. H. Wilson, 
from whose seeds the plant here figured was raised by Messrs. 
J. Veitch & Sons. Though a distinct and easily recognis- 
able form, it seems somewhat doubtful whether it should be 
considered specifically separable from the Indian P. tomen- 
tusus, Wall., for the salient differences are only to be found 
in the greater degree of tomentum on the upper surface of 
Juny, 1910.
