The genus Dipelta, founded by Maximowicz in 1877, 
differs from Diervilla (Weigelia), to which it is most closely 
allied, by the presence of the striking bracteoles at the base 
of the ovary which grow out to form dry membranous 
wings to the fruit. The species which forms the subject of 
our plate differs from every other in the genus in having 
the corolla widely inflated to the base; it appears, however, 
to be most nearly allied to D. yunnanensis, Franch., which 
differs in having entire leaves as well as in having the tube 
of the corolla contracted at the base. Like D. yunnanensis, 
the species now figured is a native of Western China, where 
both species have been found by Mr. E. H. Wilson, growing
