Plants (6–)15–35 cm. Stolons 3–8(–12) cm (leaves along stolons almost equal to those of rosettes at ends). Basal leaves 1-nerved (sometimes obscurely 3-nerved), spatulate to narrowly or broadly obovate (petiolate), 14–48 × 2.5–20 mm, tips mucronate, faces abaxially tomentose, adaxially gray-pubescent to floccose-glabrescent.

Discussion
Subspecies neodioica is most common in the eastern half of the range of Antennaria howellii; it is also found sporadically as far west as Washington and British Columbia. Antennaria virginica is likely the primary sexual progenitor of apomicts in subsp. neodioica (R. J. Bayer 1985).
