Narrative
Full name as recorded at U.S. National Arboretum: Magnolia × proctoriana. Distributed by the Arnold Arboretum in commemoration of its Centennial. Source Note: Custom grafted by Appalachian Nurseries; two grafted plants returned to USNA 7/15/72; Reference: x 7/28/72 AJF to SGM Plant List. Note: M. x proctoriana was updated as a synonym of M. salicifolia in our records in 2002, ostensibly based on GRIN Taxonomy, which may have taken into consideration opinions by Stephen Spongberg that the hybrid may only be a variant of M. salicifolia. That database lists M. x proctoriana as an accepted name today (2/28/2024) for the hybrid M. salicifolia x M. stellata, and other experts have concluded that the hybrid is authentic (see IDS, Trees and Shrubs Online), but evidently the type is not regarded as a genuine hybrid and is, in fact, M. salicifolia. As a result, the name would need to have to be conserved with a new type in order to be valid, or a different name will need to be published. At the same time, true M. salicifolia is said to survive poorly in cultivation outside of Japan (and even in Japan), and all of our material of that species has certainly died relatively soon after planting. The survivability of this material might then be an indicator of its hybrid background. -SBL
