The chromosome count is 2n = 2x = 34. It is reduced, just like in species of Phalaenopsis section Aphyllae. The karyotype is symmetrical and uniform in size. It is clear, that Phalaenopsis finleyi is closely related to Phalaenopsis section Aphyllae. Together they form a monophyletic clade. A synapomorphy is the reduction of the chromosome count.
Subfamily Apostasioideae: monophyletic - the most basal of the orchids: three fertile anthers, or two fertile anthers and a filamentous staminode. Subfamily Cypripedioideae: monophyletic - two fertile diandrous anthers, a shield-shaped staminode and a saccate (= pouch-like) lip.

Aeridinae contains the largest diversity of leafless taxa within the tribe Vandeae. These leafless species of the genera Chiloschista, Phalaenopsis, and Taeniophyllum (syn. Microtatorchis [7]), which is the most species rich genus of Aeridinae with 245 accepted species, [8] exhibit reduced stems and enhanced importance and photosynthetic function of the root system.
