The species of Deutzia are very difficult of discrimination, 
and have not hitherto been carefully studied. D. discolor 
was founded in 1887 by Mr. Hemsley on herbarium speci- 
mens collected in the Patung districts of the Hupeh 
province by Dr. Henry, who has more recently sent 
specimens of it from Szechuen. Its most distinctive 
character is that of the elongate calyx-lobes, in contrast 
to those organs in the Himalayan and Chinese D. staminea, 
Br., which is its nearest ally. The other characters 
assigned to it of discolorous leaves, densely stellately 
squamulose beneath, very long, slender pedicels, white 
flowers, and densely stellately lepidote crown of the ovary, 
are all most variable. Except in the purplish red colora- 
tion of the inflorescence and flowers I can find no differ- 
ential characters for var. purpurascens, the figure given of
