818. WISTERIA FLORIBUNDA WITH THE TORTUOUS TALE OF THE JAPANESE WISTERIA WITH THE LONGEST RACEMES

Summary The history of the Japanese Wisteria with the longest racemes is fully investigated, with a review of all the names applied to it. The name W. macrobotrys is shown to belong to a different cultivar group now widely grown under the names ‘Burford’, ‘Honko’ and ‘Hocker Edge’. The new combination W. floribunda f. multijuga (Van Houtte) J. C ompton & G. Thijsse is made in order to establish long‐term nomenclatural stability. A lectotype is designated for the hybrid name W. × formosa Rehder.
