Leaves: 8-14 fleshy lance-shaped dark green leaves with white veins, crowded around the base of the stem and extending upwards, to 25mm x 7mm. Margins smooth or wavy. 2-3 small closely sheathing stem leaves.
Flowering: Single flower to 25mm. Hood erect, constricted in the middle, sepal tip blunt. Lateral sepals narrow, drooping, free points incurved, to 10mm long. Lip fine, densely bearded, projecting forward.

Growing Conditions: Well drained sandy or loam soil in heathy woodland. Semi shade.
Garden Use: Use of orchids in gardens is not recommended, unless they already occur naturally, in which case they need to be protected. Removing orchids from the bush usually results in their death and further depletes remaining wild orchid populations.
