Description

The peduncle of the inflorescence is longer than the leaves of the plant.[5]

Distribution

The species is native to Vietnam, Malaysia, Indonesia and Thailand.[6]

Habitat

This species is terrestrial or semi-aquatic, as opposed to many other orchid species that are epiphytic. It grows in full sun in swamps near sea level.[7] The plants should be flooded during the growing season.[5] These freshwater swamp forests may grow along the edges of lakes. The soil can be very acidic, with pH values ranging between 4 and 5. [8]

Conservation

These habitats are threatened from logging, fire and land conversion. [9] Therefore, this species has been declining in Indonesia since the early 1990s. A program of the University of Riau made a restoration effort, re-planting artificially multiplied plants back into their intended habitat in 2007 and 2008. [10] Further studies on micropropagation and acclimatisation of plantlets have been undertaken. [11][12]

Use in hybridisation

It is the pollen parent of the hybrid Papilionanthe Miss Joaquim, which was originally hybridised by Agnes Joaquim.
