Comments: Lonicera tatarica and Lonicera morrowii hybridize to form Lonicera x bella, which is widely naturalized from Alberta, Canada, east to Maine, south to northern North Carolina, west to Missouri, and north through Kansas, eastern Nebraska, and the Dakotas (Batcher and Stiles, 2000). References to the literature should bear in mind that there may be considerable confusion in the identification of the taxa involved as this cross has often been confused with the two parent species and most often shares hybrid characters with both (Barnes and Cottam, 1974).
