It reflects the considerable progress in orchid taxonomy that had been made since Dressler published his classification in 1993. In the 1990s, orchid taxonomy began to be influenced by molecular phylogenetics based on DNA sequences. The first molecular phylogenetic study to include a substantial sample of orchids was published in 1999. [12]
The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of several generally shared characters: a shared terrestrial habit; sectile (capable of being severed) or granular pollinia; erect anthers.

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 leaves of D. viridis are 5–14 cm long and 2–7 cm wide; leaves at the base of the orchid are obovate to elliptical, while leaves higher on the stem become lanceolate. Two to six leaves are found on one plant, and leafing is alternate. The inflorescence of the orchid is a dense raceme (spike-like cluster) containing 7 to 70 small flowers ...
