Papilionanthe hookeriana, also known as anggrek pensil in indonesian, [3] or kinta weed, [4] is a species of orchid native to the swamps [3] of Borneo, Malaya, Sumatera, Thailand, and Vietnam. [2]
The peduncle of the inflorescence is longer than the leaves of the plant. [5]
The species is native to Vietnam, Malaysia, Indonesia and Thailand. [6]
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]
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]
It is the pollen parent of the hybrid Papilionanthe Miss Joaquim, which was originally hybridised by Agnes Joaquim.
