Description

Like other members of Phalaenopsis section Aphyllae, this plant exhibits deciduous leaflessness. However, it usually has 1-2 leaves, which are produced on up to 1 cm long stems, which are imbricated in leaf bases. The 5-7 cm long and 1.5-2.5 cm wide leaves are obliquely elliptic and show purple spotting. Verrucose, photosynthetic adventitious roots radiate from the stem. Pink to pale green, 2.9 cm wide flowers are produced on 3-6 flowered, up to 7.7 cm long racemes. A small spur is produced by the labellum.[2]

Taxonomy

The variable colouration may be a source of confusion. The flowers may be rose pink or infused with green.
The true phylogenetic relationships within the section Aphyllae are subject of dispute, which is fueled by confusion caused through various authors describing and synonymizing species within this group. Thus, species delimitation and identification is a complex matter.[3]

Ecology

This species grows in elevations of 2000 m above sea level.[2]

Conservation

International trade is regulated through the CITES appendix II regulations of international trade.[4]
