The name of this taxon appears to be invalid under the relevant nomenclatural code, as it may be a junior homonym of Acer columbianum (Penhallow).

The name of this taxon appears to be invalid under the relevant nomenclatural code, as it is a redundant synonym of Acer medianum pro parte, typic and Acer tigilense pro parte, non-typic.

Notes: Jr synonym of Acer columbianum Penhallow, 1908, itself a nomen nudum name. Referred specimens placed into Acer medianum pro parte, typic (leaves) and Acer tigilense pro parte, non-typic (fruits) by Wolfe and Tanai, 1987
