Native of W. China; introduced by Wilson in 1904 under his W. 1731, but known earlier from specimens collected by the Russian explorer Potanin. It is quite hardy and a good grower, flowering and bearing fruit freely. It is related to B. diaphana but in that species the inflorescence is a fascicle or very condensed raceme with at the most five flowers. B. consimilis and B. faxoniana are related species, described by Schneider from plants growing in the Arnold Arboretum.
