Plants 20–75 cm. Roots numerous, slender, mostly to 0.8 cm diam. Leaves persisting through anthesis, to 7, primarily basal reduced to sheathing bracts upward on stem, spreading, linear to linear-lanceolate, 10–25 × 1–5 cm.

Discussion
Typical plants are easily recognized by the stark white flowers with green venation of the lip. In forma albolabia P. M. Brown & C. McCartney, the lip appears pure white but the raised veins are actually a pale yellow. Plants with creamy green to green flowers, usually in tight spirals, and incurved lateral sepals are local to frequent in north-central Florida and scattered westward in the Gulf counties to eastern Texas.
Hybrids of Spiranthes praecox with S. vernalis are known as Spiranthes ×meridionalis P. M. Brown.
