It has a single fleshy, channelled, dark green leaf and up to fifteen green flowers with reddish lines. 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. DescriptionCalochilus montanus is a terrestrial, perennial, deciduous, herb with an underground tuber and a single fleshy, channelled, dark green, linear to lance-shaped leaf, {{convert|150-250|mm|in|sigfig=1|abbr=on}} long and {{convert|7-15|mm|in|sigfig=1|abbr=on}} wide. The leaf is fully developed when the first flower opens. Between two and fifteen green flowers with reddish lines are borne on a flowering stem {{convert|400-900|mm|in|sigfig=1|abbr=on}} tall. The dorsal sepal is more or less erect, {{convert|9-12|mm|in|sigfig=1|abbr=on}} long and {{convert|4-6|mm|in|sigfig=2|abbr=on}} wide. The lateral sepals are a similar length but narrower. The petals are {{convert|5-7|mm|in|sigfig=1|abbr=on}} long and {{convert|3-4|mm|in|sigfig=1|abbr=on}} wide. The labellum curves forwards and is {{convert|11-15|mm|in|sigfig=1|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide with two shiny metallic blue to purple plates near its base. The middle part of the labellum has bristly hairs up to {{convert|4|mm|in|sigfig=1|abbr=on}} and the tip has a glandular "tail" {{convert|3-4|mm|in|sigfig=2|abbr=on}} long. The column has two purple "eyes" but lacks a ridge between them. Flowering occurs from October to December.[2][3]Taxonomy and namingCalochilus 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.[3]Distribution and habitatThe mountain beard orchid grows in open forest on mountain slopes. It occurs in the Australian Capital Territory and in New South Wales south from the Moonbi Range.[2][3] References1. ^{{WCSP | 346304 | Calochilus montanus}} {{Taxonbar|from=Q15496236}}2. ^1 2 {{cite book|last1=Jones|first1=David L.|title=A complete guide to native orchids of Australia including the island territories|date=2006|publisher=New Holland|location=Frenchs Forest, N.S.W.|isbn=1877069124|page =259}} 3. ^1 2 {{cite journal |last1=Jones |first1=David L. |title=New taxa of Australian Orchidaceae |journal=Australian Orchid Research |date=2006 |volume=5 |page =66}} 4. ^{{cite web|title=Calochilus montanus|url= https://id.biodiversity.org.au/instance/apni/616265|publisher=APNI|accessdate=24 June 2018}} 5. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page =536}} 5 : Calochilus|Endemic orchids of Australia|Orchids of New South Wales|Orchids of the Australian Capital Territory|Plants described in 2006 |
