Phalaenopsis taenialis, also known as 小尖囊蝴蝶兰 (xiao jian nang hu die lan) in Chinese,[2] is a species of epiphytic orchid occurring from the eastern Himalaya to China (Yunnan).

[1] The specific epithet taenialis is derived from the long, flattened roots, which resemble tapeworms.

[2] This species closely resembles the newly published species Phalaenopsis arunachalensis, which as of March 2022 is not currently accepted by the World Checklist of Selected Plant Families (WCSP) of the Royal Botanic Gardens Kew, as well as Phalaenopsis honghenensis.

The flowers of Phalaenopsis taenialis turn yellow or orange as a result of post-pollination changes.

The original description of Doritis braceana was based on Phalaenopsis taenialis specimens showing these changes in flower colour.

Before the establishment of CITES regulations on international trade, specimens collected from the wild were commonly exported from northeast India.
