The Spiral Sun-orchid Thelymitra matthewsii is a small, colorful, seasonal terrestrial orchid occurring in south-eastern Australia and also on the North Island of New Zealand. In Australia it is widely but sporadically distributed from Genoa in eastern Victoria to Kangaroo Island in South Australia. Little is known of the biology and ecology of the species, or of previous decline or threats. Currently there are about 30 populations containing about 1,500 plants, although most populations are small and all are relatively isolated. Current threats include disturbance to or destruction of plants and habitat, altered fire regimes, grazing/predation and weed invasion.
The Spiral Sun-orchid is listed as Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. It is also listed as Threatened under the Victorian Flora and Fauna Guarantee Act 1988, and Endangered under the South Australian National Parks and Wildlife Act 1972. This national Recovery Plan for the Spiral Sun-orchid is the first recovery plan for the species, and details its distribution, habitat, threats and recovery objectives and actions necessary to ensure its long-term survival.
