Orchids are plants that belong to the family Orchidaceae (/ ˌ ɔːr k ɪ ˈ d eɪ s i. iː,-s i. aɪ /), [2] a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers.
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.
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 ...
Dancing lady orchids are light loving orchids that can live in 40-70% humidity. I also love boat orchids ( Cymbidium ). They are cool growing, so they work well in indoor environments, provided ...
Asparagales (asparagoid lilies) are a diverse order of flowering plants in the monocots.Under the APG IV system of flowering plant classification, Asparagales are the largest order of monocots with 14 families, [5] 1,122 genera, and about 36,000 species, with members as varied as asparagus, orchids, yuccas, irises, onions, garlic, leeks, and other Alliums, daffodils, snowdrops, amaryllis ...
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.
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.
Aside from cotyledon number, other broad differences have been noted between monocots and dicots, although these have proven to be differences primarily between monocots and eudicots. Many early-diverging dicot groups have monocot characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen. [5]
