Solidago altiplanities Taylor & Taylor is native to mixed gypsum and shale soils, rocky slopes, escarpments, and ridges in the high plains of Panhandle Texas and adjacent Oklahoma.  It is similar to S. juliae but less pubescent and similar to S. altissima var. gilvocanescens but with narrower leaves ().  Statistical support for recognizing the S. altiplanities was presented by Semple et al. (2015) in a multivariate analysis of the S. altissimacomplex. One diploid count 2n=18 has been reported for the species. Semple (2023) mapped the cytogeography of S. altiplanities.

Solidago altiplanities was included in S. subsect. Triplinerviae ¾±²ÔÌý, but was found to be more closely related to S. radulaÌý²¹²Ô»åÌýS. velutina in S. subsect. Radulae (Semple and Beck 2021; Semple et al. 2023).
