A Phalaenopsis flower. Orchids are easily distinguished from other plants, as they share some very evident derived characteristics or synapomorphies.Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds.
When Dressler published his classification in 1993, the relationships of orchids to other monocots was still unknown. Some of the first molecular phylogenetic studies of monocots resolved the Orchidaceae as sister to the astelioid clade of the order Asparagales , but this result never had strong statistical support.
Largely herbaceous plants that generally grow in soil or on other plants. Orchids are the largest family of vascular plants, with more than 26,000 species and 100,000 recorded cultivars. Vanilla is derived from the fermentation of Vanilla planifolia. Cattleya, Cymbidium, Oncidium, Phalaenopsis, Paphiopedilum and Vanda are commonly grown ...
The Cronquist system is a taxonomic classification system of flowering plants.It was developed by Arthur Cronquist in a series of monographs and texts, including The Evolution and Classification of Flowering Plants (1968; 2nd edition, 1988) and An Integrated System of Classification of Flowering Plants (1981) (see Bibliography).
English: This diagram is showing the differences between monocotyledonous plants and dicotyledonous plants. Monocots have a single cotyledon and long and narrow leaves with parallel veins. Their vascular bundles are scattered. Their petals or flower parts are in multiples of three. Dicots have two cotyledons and broad leaves with network of veins.
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.
5. Ascocenda Orchids. Known for having colors ranging from pink and purple to orange, brown, scarlet or deep fuchsia, these orchids have petals that tend to roll under, making it appear like a ...
