Phalaenopsis tsii

Phalaenopsis tsii is a small epiphytic orchid in the Hygrochilus group (subgenus Hygrochilus), described in 2016 from Mount Shunhuang in Hunan, south-east China, where it grows on tree trunks at 1,200–1,850 m. It has short stems and 7–10 cm leaves, and its greenish, brown-spotted flowers have a large white lip and a horn-shaped spur. It comes from a subtropical mountain with cold winters, so it needs cooler conditions than typical Phalaenopsis.

Where it grows wild

It grows on tree trunks in montane forest on Mount Shunhuang in southern Hunan. At this elevation the monsoon climate brings warm, wet summers and cold, drier winters, with occasional frost and snow.

It grows at 1,200–1,850 m, higher than its relative P. subparishii at 300–1,100 m. It should be treated as a cool-intermediate orchid.
