Leaves: blade distinctly lined with white or greenish white on veins throughout, broadly elliptic to broadly ovate, 2.1–6.2 × 1.3–3 cm, apex acute or obtuse. Inflorescences 10–57-flowered, cylindric (equally dense on all sides); peduncle 11–35 cm. Flowers: lateral sepals 3.1–5.3 mm; petals distinct; hood 3.6–5.7 mm; lip scrotiform, 2.5–4.2 × 2.2–3.5 mm, apex reflexed, outer surface slightly tuberculate, inner surface with somewhat thickened veins, without glandular processes; anther inflexed, immersed in cupshaped clinandrium, apex blunt; pollinia blunt; rostellum with marginal notch 0.1–0.4 mm deep; viscidium orbiculate. 2n = 26.


Phenology: Flowering mid Jul–early Sep.
Habitat: Almost any wooded habitat with acid surface conditions, most frequent on moist humus soils in shady, upland woods of hemlock, pine, oak, or maple, less frequent in lowland woods, bogs, swamps
Elevation: 0–1600 m
