Solidago buckleyi
Solidago ouachitensis
Solidago buckleyi is an uncommon species of mesic woods, most variable in the size and number of teeth on the large mid cauline leaves. Once seen, usually it is not easily confused with S. petiolaris. Reports from farther east are for plants of S. petiolaris.

Of conservation concern.
Historically Solidago ouachitensis has been included in S. caesia or S. curtisii; it is ecologically and morphologically distinct.
Solidago ouachitensis is known only from the mesic, north-facing slopes of the Ouachita Mountains along the border of Arkansas and Oklahoma. It is a very infrequent species deserving protection and is in the Center for Plant Conservation’s National Collection of Endangered Plants.
