Flowers - Small, green, 5mm long, glabrous. Floral tube 2mm long. Upper sepals deflexed, 2mm long. Lower sepals rounded at the apex, 2mm long, the margins revolute. Lateral petals thin, linear, to 1.5mm long, recurved. Corolla lip 2-lobed, 2.5-3mm long. The lobes acute. The upper lip whitish-green. Column 3-lobed (the lobes acute), .75mm long.

Flowering - May - July.

Habitat - Mesic to dry upland woods, typically on acidic substrates.
