Description

Prasophyllum is a genus of relatively inconspicuous ground orchids with single clustered spikes of small flowers which may be white, green or reddish and that are non-resupinate (i.e. ‘upside down’ relative to most other orchids) and a single tubular, not flat, leaf. This leaf distinguishes them from the very similar midge orchid genus (Genoplesium), which has recently been created by splitting Prasophyllum. Kiandra Leek Orchid (formerly P. morganii) flowers open very widely and are green with deep purple stripes and blotches, or they may be completely purple. They are sweet-smelling and are arranged densely in a single spike of up to 80 flowers. The single hollow leaf is up to 30 cm tall.

Distribution

All populations are thought to occur within Kosciuszko NP (in the Long Plain, Kiandra, Tantangara area).

Habitat and ecology

  • The species occurs in subalpine grasslands and woodlands.
  • Flowering has been recorded between October and December.
  • Flowers are followed by a fleshy seed capsule.
  • Plants retreat into subterranean tubers after fruiting, so are not visible above-ground.
