The Deutzia which we here figure was originally dis- 
covered by the Abbé David near Moupine in Szechuan and 
was subsequently collected in various localities in the same 
province by Mr, E. H. Wilson at altitudes of from 5,000 to 
9,000 feet above sea level, when collecting on behalf of 
Messrs. J. Veitch & Sons, in 1901, and again during his 
latest Chinese journey. The species was first introduced 
into cultivation through the Coombe Wood Nursery of the 
Messrs. Veitch in January, 1902, as an unnamed Deutzia. 
In 1905 it was named D. Veitchii on their behalf by Mr, 
Wilson, and under that name it has become well known and 
widely established in collections and has been recognised by 
the Royal Horticultural Society. Thanks, however, to the 
kindness of Professor Lecomte, who has kindly placed at 
our disposal for study the specimen on which Mr. Franchet's
