Calochilus praealtus, commonly known as the lofty beard orchid, is a species of orchid endemic to the Northern Tablelands of New South Wales. It has a single pale green leaf and up to six pale green flowers with faint red stripes and a labellum with a dark purple beard. It is only known from two mountainous areas.

Description

Calochilus praealtus is a terrestrial, perennial, deciduous, herb with an underground tuber and a single pale green leaf Шаблон:Convert long, Шаблон:Convert wide and fully developed at flowering time.

The lateral sepals are a similar length but only about half as wide and spread apart from each other. The petals are Шаблон:Convert long, about Шаблон:Convert wide, asymmetrically egg-shaped with a small upturned tip.

Taxonomy and naming

Calochilus praealtus was first formally described in 2006 by David Jones from a specimen collected in Mount Kaputar National Park and the description was published in Australian Orchid Research.[3] The specific epithet (praealtus) is a Latin word meaning "very high".[4]

Jones gave the species the name Calochilus praeltus, misspelling the Greek word and mentioning that its meaning is "high altitude, elevation; in reference to its occurrence at high altitudes". The misspelling has been copied by the Australian Plant Name Index.[1][2][3]

Distribution and habitat

The lofty beard orchid grows with grasses in snow gum woodland. It is only known from Barrington Tops and the Mount Kaputar National Park.[1]
