High-plains Goldenrod

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 (Semple & Cook 2006 FNA).  Statistical support for recognizing the S. altiplanities was presented by Semple et al. (2015) in a multivariate analysis of the S. altissima complex. One diploid count 2n=18 has been reported for the species.
