The leaf is bluish green with whitish veins on the upper surface and shiny greenish purple on the lower side. The flower is reddish to reddish purple, 12–14 mm (0.5–0.6 in) long and leans downwards. The dorsal sepal is 11–12.5 mm (0.4–0.5 in) long and 4.5–6 mm (0.18–0.24 in) wide and curved, expanding to a dished egg-shape. The lateral sepals and petals linear, about 5 mm (0.2 in) long, 0.5 mm (0.02 in) wide and curve around the side of the labellum. The labellum is reddish, forms a tube 13–14 mm (0.5–0.6 in) long, about 15 mm (0.6 in) wide with glistening dark red calli along its centre. Flowering occurs in June and July.[2][3][4][5]

Taxonomy
Corybas montanus was first formally described in 1988 by D.L.Jones and the description was published in Austrobaileya from a specimen collected on Mount Maroon.[6] The specific epithet (montanus) is a Latin word meaning "of mountains",[7] referring to the habitat of this species.[3]
Distribution and habitat
The montane helmet orchid is self-pollinating and grows on slopes in open forest on Mount Maroon.[2][4]
Conservation
Corybas montanus is classified as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999. The main potential threat to the species is illegal collection.[4]
