Spiraea Henryi was discovered by Mr. A. Henry in 
Hupeh, near Ichang, in 1885, and later in Szechuen, but 
for its introduction to cultivation our gardens are indebted 
to Messrs. J. Veitch & Sons of Chelsea, whose collector, 
Mr. E. H. Wilson, found it in 1900, also in Hupeh. It 
belongs to the section Chamaedryon (Ser. in DC. Prodr. ii. 
_p. 542), and, like many of its allies, is a very charming 
acquisition. Among older species it is most closely related 
to S. canescens, D. Don, and its flowers, as in that species, 
are arranged in rounded corymbs on the upper side of long 
arching branches; its nearest ally is, however, S. Wilsoni, 
Duthie (Hort. Veitch. p. 379), which is also described as 
having the peduncles and pedicels covered with silky hairs, 
but is in reality almost glabrous. In mid-June, 1908, it 
was one of the most beautiful deciduous shrubs in flower 
at Kew. Mr. Henry observes that its leaves are used by 
the poorer natives as a substitute for tea.
