Phalaenopsis marriottiana

A small, fragrant Phalaenopsis in subgenus Hygrochilus, long treated as a variety of P. hygrochila (Hygrochilus parishii) until DNA work showed it is distinct. It grows in seasonally dry montane forest in northern mainland South-East Asia and flowers in winter and spring, carrying 2–6 brownish-purple or pink-and-yellow flowers. It is a cool- to intermediate-growing epiphyte that wants a cooler, somewhat drier winter.

Where it grows wild

An epiphyte, also recorded on limestone cliffs, in deciduous montane forest and the adjacent foothills. These forests lose much of their canopy in the dry season, so the plants get bright light in winter.

The literature gives about 1300 m; the related P. hygrochila grows at 700–1300 m. None of the four GBIF records carries an elevation.
