Description

The Small Snake Orchid is a member of the ‘Donkey’ orchid group, with bright yellow striped flowers and two drooping side petals. The flowering stem is less than 10 cm tall and has one or two flowers with dark stripes. The top petal is more orange than the rest of the flower and has a bright purple centre. The two thin leaves are up to 16cm long.

Distribution

Confined to north east NSW. It was originally found scattered from Tenterfield south to the Hawkesbury River, but is now mainly found on the New England Tablelands, around Armidale, Uralla, Guyra and Ebor.

Habitat and ecology

  • The Small Snake Orchid grows on grassy slopes or flats.
  • Often on peaty soils in moist areas.
  • Also on shale and trap soils, on fine granite, and among boulders.
  • It flowers during August-October.
  • Pollination is mostly by sexual deception, with the Small Snake-orchid attracting mostly males of an native bee Halictus lanuginosus. However, the flowers produce nectar and emit a strong scent that attracts a range of other pollinators.
