Heterotheca villosa var. sierrablancensis Semple is native to mid to higher elevations in the White Mts. of New Mexico. The variety has ovate-oblong, moderately densely strigose and sparsely to moderately densely glandular leaves. Nesom (2020) treated it as a separate species H. sierrablancensis (Semple) Nesom, which might be justified pending further research.
