Synonym: Linguella nana

Description: Perennial herb rising from round tubers to form large colonies. Central sepal and petals united into a galea (hood) over the column and labellum (lip). Lateral sepals joined at the base, ending in fine points.
Leaves: Rosette of 3-10 stalked dull green egg-shaped leaves 5-20mm x 3-10mm, around the base of the stem, margins wavy. 1-2 small stem-clasping leaves.
Flowering: Single flower to 20mm. Hood mostly upright, top curved forward through gap, petals flared, tips blunt. Lateral sepals erect, gap broad, ridged, points upright for 5-25mm, clubbed. Lip not visible.

Flowering Time: July to October
Growing Conditions: Moist well drained soil in heathy woodland and forests. Size will vary with moisture levels. Full sun to full 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.
