| Tasmania
has one living species of Thynninorchis (elbow
orchids), it is very rare. This species T. nothofagicola
(myrtle elbow orchid) is among the most cryptic of orchids,
being short, very slender, dark green in colour, and
matching in colour the mossy rainforest understorey it
inhabits.
The sepals and petals are all very reduced and
inconspicuous, and the labellum is elongated, with a
freely pivotting hinge about mid-way.
Another species (T. huntiana) was known from
Flinders Island, but is now considered to be extinct.
