TAXONOMY : 
Bigtooth maple (Acer grandidentatum) is closely related taxonomically to
sugar maple (A. saccharum).  Some populations in Oklahoma and Texas
where the range of these two taxa overlap exhibit varying degrees of
morphological intermediacy [24,37], making identification at the species
level difficult.  Morphological similarities have caused some botanists
to question whether bigtooth maple should be considered a separate
species or a variety of sugar maple (Acer saccharum var. grandidentatum)
(Nutt.) Sarg. [4,24].  Numerous authorities, however, recognize these
maples as separate entities.  In general, bigleaf maple is a much
smaller tree and has smaller leaves than sugar maple [35].  The
currently accepted scientific name of bigleaf maple is Acer
grandidentatum Nutt. [28,29,30,39,68].  Recognized varieties include:

                var. grandidentatum
                var. sinuousum (Rehd.) Little
