The East Lynne Midge Orchid has 10 to 25 flowers densely crowded onto a spike less than 4 cm long, on a stem less than 25 cm tall. Individual flowers are approximately 4 mm across and are dark purplish-black. Flowers appear from mid November to late December. When not in flower, only the thin, green leaf is present above ground. Genoplesium is a genus of relatively inconspicuous ground orchids with clustered spikes of dark-coloured flowers that are non-resupinate (i.e. they are ‘upside down’ relative to most other orchids) and have a single flat, not tubular, leaf. This leaf distinguishes them from the very similar genus Prasophyllum, the leek orchids, their closest relatives.


The East Lynne Midge Orchid is currently known from only a narrow belt, approximately 12 km wide, of predominantly Dry Sclerophyll Forest from 17 km south of Batemans Bay to 24 km north of Ulladulla.

Habitat and ecology

  • The East Lynne Midge Orchid grows in dry sclerophyll woodland and forest extending from close to the coast to the adjoining coastal ranges.
  • Confined to areas with well-drained shallow soils of low fertility, often occurring near the crests of ridges and on low rises where the ground cover is more open and sedge dominated rather then being shrubby.
  • Each plant produces a single leaf-like stem that emerges from an underground tuber. The orchid stems can appear from late October and take only a few weeks to produce flowers. Many stems that emerge do not produce flowers.
  • The species generally flowers between early November and mid December. The fruit then take several weeks to ripen.
  • The old fruiting stems (as well as non fruiting stems) then persist until late winter, at which time they wither and the plant dies back to a small, dormant underground tuber.
  • Has some limited ability to re-colonise previously disturbed sites.
