Flowers: sepals persistent, broadly lanceolate, to 4 mm, apex acuminate; petals white to purplish pink, paler at base, elliptic-ovate, to 9 mm; stamens (6–)7–18; stigma 1, subcapitate, sometimes 3-lobed. Capsules ovoid, strongly trigonous, 5–7 mm. Seeds without arcuate ridges, 1 mm.
Phenology: Flowering Jun–Sep.
Habitat: Woodland openings and bare slopes and summits in rocky soil on chert, basalt, and cinder

Discussion
The more recently described Phemeranthus thompsonii may be indistinct from P. validulus and perhaps should be merged with it.
