Distribution The species is native to Vietnam, Malaysia, Indonesia and Thailand.Papilionanthe hookeriana (Rchb. fil.) Schltr. data, Encyclopedia of Life. Retrieved July 30, 2021.
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.Genera Orchidacearum Vol 6, Alec M. Pridgeon et al. (editor), First edition, 2014, Oxford University Press, p. 219 (PAPILIONANTHE). The plants should be flooded during the growing season. 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. Wiryono, W., Mersyah, R., & Tarantona, M. (2020).

Conservation These habitats are threatened from logging, fire and land conversion. Mary Rose C. Posa, Lahiru S. Wijedasa, Richard T.

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. Roilan (2016).
