Scapes ebracteate, barely elongating after flowering. Inflorescences compact racemes. Flowers: sepals barely connate proximally; petals distinct nearly to base, corolla urceolate, 3.5-8 mm, lobes white, margins entire; anthers 1-locular, without basal spurs, transversely dehiscent; filaments and staminodes connate basally, forming coronalike tube adnate to corolla base, free distally; staminodes present. x = 6.

Species 1: e United States.

Prior to 1972, the single species of Galax was known as G. aphylla Linnaeus; the type of that name was shown by R. K. Brummitt (1972) to represent a species of Nemophila (Hydrophyllaceae). Because Galax Linnaeus 1753 was based on the Nemophila type, the later name Galax Sims has been conserved.
