On the Lonicera buschiorum Pojark. (Caprifoliaceae)

The morphological differences of the species L. buschiorum Pojark., L. caerulea L. s. str., L. pallasii Ledeb. and L. stenantha Pojark. traditionally included in L. caerulea s. l. are shown. The treatment of the Caucasian race of L. caerulea s. l. as a separate species L. buschiorum is considered reasonable.
