Developments in Mahonia

摘要

Julian Shaw discusses some new and not-so-new mahonias, clarifies their identities and provides names for them. Two YEARS AGO, plantsman Roy Lancaster discussed Chinese Mahonia that had been introduced to cultivation in the past two decades (Lancaster 2009). It has been my privilege to assist him and others with further studies of cvitivated Mahonia. This article presents the results of that research and, as a result, several new taxa are described and cultivar names validated.
