Description

The Superb Midge Orchid has flower spikes to 6 cm long, with 4-18 flowers on each spike. Individual flowers have dark pinkish-purple labellum and sepals of orange to purple. They are approximately 12 mm across although sometimes larger. Flowers appear late February-March, generally in response to reasonable spring/summer rains. 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.

Distribution

The Superb Midge Orchid is restricted to the Central and Southern Tablelands of NSW where it has been recorded from 2 locations near Nerriga, c. 20 km apart, and north of Wallerawang. Some plants occur in Morton National Park.

Habitat and ecology

  • The Superb Midge Orchid occurs predominantly in wet heathland on shallow soils above a sandstone cap but has also been found in open woodland interspersed with heath and dry open shrubby woodland.
