Calochilus therophilus, commonly known as the mountain beard orchid,[2] is a species of orchid endemic to New South Wales and the Australian Capital Territory.

The labellum has two shiny metallic blue to purple plates near its base and there is no ridge between the two "eyes" on the column.

Calochilus montanus is a terrestrial, perennial, deciduous, herb with an underground tuber and a single fleshy, channelled, dark green, linear to lance-shaped leaf, 150–250 mm (6–10 in) long and 7–15 mm (0.3–0.6 in) wide.

[2][3] Calochilus montanus was first formally described in 2006 by David Jones and the description was published in Australian Orchid Research from a specimen collected on Black Mountain in the Australian Capital Territory.

[4] The specific epithet (montanus) is a Latin word meaning "of mountains",[5] referring to the habitat of this species.
