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.
All show a unique development of the single anther: it is incumbent, meaning that it forms a right angle with the column axis or pointed backward in many genera. Most have hard pollinia , i.e. a mass of waxy pollen or of coherent pollen grains; pollinia with caudicle and viscidium or without; stigma entire or 3-lobed; rostellum present; 1 ...
Phalaenopsis orchid showing monopodial form of growth Vascular plants with monopodial growth habits grow upward from a single point. They add leaves to the apex each year and the stem grows longer accordingly.
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)
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 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 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.
Phalaenopsis maculata is a species of orchid endemic to Peninsular Malaysia and Borneo. [1] The specific epithet maculata , from the Latin maculatus meaning "spotted", refers to the floral colouration.
