Crataegus Columbiana
The name ''Crataegus columbiana'' is a source of considerable confusion. The species named by Thomas J. Howell is now considered to be the same as '' C. douglasii'', named earlier, and the earlier name should be used instead. However, some varieties of ''C. columbiana'' have also been named that are not related to ''C. douglasii''. ''C. columbiana'' has been used by some authors for '' Crataegus piperi'' Britton, which is now known as ''C. chrysocarpa'' var. ''piperi''.Phipps, J.B.; O’Kennon, R.J. (2004).
