Mahonia breviracema is cultivated in Yan Shan Botanical Garden, Guangxi Institute of Botany, Guilin, from where the type specimen (S. K. Lee 200582, IBK) was collected. Mahonia monodens, described from Guangxi (Tiandeng) and Guizhou, is tentatively included in synonymy, but we have not been able to compare the limited number of specimens available to determine the appropriateness of this placement.
