Phyllaries green, margins sometimes ciliate, apices erect, acute to obtuse, mucronate, faces densely villous. Cypsela faces sericeous.

Discussion

Variety pinetorum is recognized by its strict habit, villous stems and phyllaries, and relatively large heads in open racemiform arrays. It is thought to be most closely related to var. congesta (D. D. Keck 1940).
