TAXONOMY : 
There has been considerable disagreement over the taxonomy of the Salix
exigua complex.  Entities in this complex have been interpreted
variously as distinct species [1,15,16] or as subspecies
[7,10,22,27,62].  However, because the Salix exigua complex has many
forms and freely interbreeding intermediates, ranking entities at the
subspecific level appears to be more correct.  The fully documented
scientific name of sandbar willow is Salix exigua Nutt.  Recognized
subspecies and varieties [7,10,22,27,62], and a proposed variety [10]
are:

Salix exigua 
             ssp. exigua
                  var. exigua
                  var. stenophylla
         
             ssp. interior
                  var. pedicellata
                  var. interior
