  • Now considered a subspecies.  Formerly Alnus viridis subsp. sinuata, now Alnus alnobetula subsp. sinuata.
  •  Taxonomy: The Latin name Alnus viridis (Chaix) DC (1785) has long been attributed to green and Sitka alders; however, a closer look at the literature reveals that the name Alnus alnobetula  (Ehrh.) K. Koch has priority, since the latter name was published two years earlier, in 1783  (Chery, J., PhytoKeys 2015; (56): 1–6).  Hence the specific epithet alnobetula takes precedence over viridis.
  • Recent studies have shown that Sitka Alder is part of a circumpolar alder group (Alnus alnobetula) distributed across America, Europe, and Asia.  This species has been separated into two subspecies, namely (1) A. alnobetula supsp. crispa - Green Alder - northern North America, including the Northwest, and (2) A. alnobetula subsp. sinuata - Sitka alder.
