TAXONOMY : 
Sitka alder is described under a variety of scientific names by numerous
authors.  The most commonly used scientific name, which designates Sitka
alder as a distinct species, is Alnus sinuata (Reg.) Rydberg
[25,27,29,35].  However, more recent studies have shown Sitka alder to
be a member of a circumpolar taxon distributed across America, Europe,
and Asia [18].  This taxon has been separated into the following two
subspecies [18,20,30]:

      Alnus viridis ssp. crispa (Aiton) Turill - green alder - northern
                                                 North America, including
                                                 northwestern N. America
                                                      
      Alnus viridis ssp. sinuata (Regel) Love & Love - Sitka alder -
                                                 northwestern North
                                                 America  

Intermediate forms between these subspecies are found where their ranges
overlap [5,18].
