Description

Pleione coronaria is an epiphytic orchid. It has prominent egg-shaped swellings at the base of the stem, which are known as 'pseudobulbs' (2). The flower stalk (or inflorescence) stands vertically and bears a single pale pink flower (2). The flower is long and slender and the lip is marked with red spots towards the tip and has a series of pronounced ridges in the centre (2). Each pseudobulb has a single leaf associated with it (2).

Range

This rare orchid is only found in the Ganesh Himal region of central Nepal (2).

Habitat

Found in mountainous areas at heights of between 2,500 and 3,500 metres above sea level; associated with rhododendron forests and old Tsuga dumosa trees in a moist climate (3).

Biology

This Pleione flowers in spring (3). It has been observed growing amongst moss on the inner branches of trees, quite often close to the ground (3).

Threats

Pleione coronaria has an extremely limited range and the area in which it is found has been heavily deforested, possibly endangering this species further (2). It is unlikely that this orchid is under threat from collection due to the inaccessibility of its habitat (3).

Conservation

More information on the distribution and status of this species in the wild is required before any conservation measures can be implemented.
