Helmet orchids are small, perennial, deciduous herbs and are nearly always terrestrial. They have a single leaf at their base and a single flower on a short stalk, the flower dominated by its large dorsal sepal and labellum. Species of Corybas are found in Australia, New Zealand, New Guinea, Southeast Asia, the Himalayas, southern China, many Pacific islands and a few sub-Antarctic islands.

Corybas sulcatus, also known as the grooved helmet-orchid, is one of two helmet orchids endemic to Australia’s subantarctic Macquarie Island, and the second to be discovered. The specific epithet comes from the Latin sulcatus – “grooved”, with reference to the prominent groove in the labellum boss. It is a small, terrestrial, tuberous, herbaceous plant that forms clonal colonies. The flower is erect, mostly dark red, 25–30 mm long and 10–14 mm wide. The flowering period is November–December. It occurs on the plateau uplands of the island, growing in wet grassy seepage areas. It can be distinguished from the only other orchid on the island, Corybas dienemus, by its dark red flowers.
Corybas dienemus, commonly known as the windswept helmet-orchid, is one of two helmet orchids endemic to Australia's subantarctic Macquarie Island, and the first orchid to be found there. It is a relatively small orchid with green flowers with purplish-red markings and was discovered in 1978.
