Phalaenopsis abbreviated Phal in the horticultural trade, is an orchid genus of approximately 60 species. Phalaenopsis is one of the most popular orchids in the trade, through the development of many artificial hybrids.
They are native throughout southeast Asia from the Himalayan mountains to the islands of Polillo, Palawan and Zamboanga del Norte in the island of Mindanao in the Philippines and northern Australia. Orchid Island of Taiwan is named after this genus. Little recent information about their habitat and their ecology in nature is available since little field research has been done in the last decades.
