TAXONOMY : 
Dispute over the taxonomic placement of Cercocarpus betuloides Nutt. has
been considerable.  Martin's [32] 1950 taxonomic revision of the genus
Cercocarpus reduced C. betuloides to several varieties of C. montanus
Raf. [see SYNONYMS above].  Some taxonomists have adopted Martin's
revision [19,20,47], while others treat C. betuloides and C. montanus as
distinct species [21,30,37].  In this report, C. betuloides is
recognized as a distinct species, birchleaf mountain-mahogany, found in
southern Oregon, California, and Arizona.  Plants found in the
Intermountain and Rocky Mountain regions are C. montanus, true
mountain-mahogany.

Munz [37] recognizes three varieties of birchleaf mountain-mahogany:

  var. betuloides
  var. blancheae (Schneid.) Little
  var. macrourus (Rydb.) Jeps.

Plants on Santa Catalina Island off the coast of southern California
were once considered a fourth variety, var. traskiae (Eastw.) Dunkle,
but are now recognized as a distinct species:  C. traskiae, Catalina
mountain-mahogany [30,37].
