Phalaenopsis (/ ˌ f æ l ɪ ˈ n ɒ p s ɪ s /), also known as moth orchids, [2] is a genus of about seventy species of plants in the family Orchidaceae.Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end.
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.
The following is a list of intergeneric hybrids recognised by the Royal Horticultural Society that includes species of Phalaenopsis as ancestors, as at February 2022: [6]. × Aeridopsis (Aerides × Phalaenopsis)
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.
The term monophyly, or monophyletic, derives from the two Ancient Greek words μόνος (mónos), meaning "alone, only, unique", and φῦλον (phûlon), meaning "genus, species", [4] [5] and refers to the fact that a monophyletic group includes organisms (e.g., genera, species) consisting of all the descendants of a unique common ancestor.
