Orchids are plants that belong to the family Orchidaceae, 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 world's richest diversity of orchid genera and species is found in the tropics.
Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
Phalaenopsis, also known as moth orchids, 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. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.
Vanilla, the vanilla orchids, forms a flowering plant genus of about 110 species in the orchid family (Orchidaceae). The most widely known member is the flat-leaved vanilla, native to Mexico and Belize, from which commercial vanilla flavoring is derived. It is the only orchid widely used for industrial purposes in flavoring such products as foods, beverages and cosmetics, and is recognized as the most popular aroma and flavor. The key constituent imparting its flavour is the phenolic aldehyde, vanillin.
Prasophyllum, commonly known as leek orchids, is a genus of about 140 species of flowering plants in the orchid family, Orchidaceae and is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. The common name arises from their having a hollow, leek- or onion-like leaf. Some species only flower after summer fires and have flowers similar to those of Xanthorrhoea which flower at the same time, suggesting that they employ the same pollinating insects. Leek orchids are similar to those in the genus Genoplesium except that the free part of the leaf is cylindrical and the labellum has a solid connection to the column. They range in size from the little laughing leek orchid at about 15 cm (6 in) to the king leek orchid which grows up to 2 m (80 in) tall.
Tipularia discolor, the crippled cranefly or crane-fly orchid, is a perennial terrestrial woodland orchid, a member of the family Orchidaceae. It is the only species of the genus Tipularia found in North America. It occurs in the southeastern United States from Texas to Florida, the range extending north into the Ohio Valley and along the Appalachians as far north as the Catskills. There are also isolated populations in Massachusetts and in the Great Lakes region. Tipularia discolor is a common early pioneer during secondary succession, readily colonizing woodland habitats during early developmental or regrowth stages.
Neotinea ustulata, the burnt orchid or burnt-tip orchid, is a European terrestrial orchid native to mountains in central and southern Europe, growing at up to 2,400 m (7,900 ft) elevation. The plant is considered Endangered in Great Britain and Least Concern internationally based on IUCN Red List criteria. The burnt-tip orchid was voted the county flower of Wiltshire in 2002 following a poll by the wild flora conservation charity Plantlife.
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in clonal plants that are genetically identical to the parent plant and each other, unless mutations occur.
Ghost plant is a common name for several plants and may refer to:
Pachylia ficus, known as the fig sphinx, is a moth of the family Sphingidae. It lives from the northern tip of South America in Uruguay through Central America to the southern tip of the United States straying into Arizona and Texas.
Vanilla planifolia is a species of vanilla orchid native to Mexico, Central America, Colombia, and Brazil. It is one of the primary sources for vanilla flavouring, due to its high vanillin content. Common names include flat-leaved vanilla, and West Indian vanilla. Often, it is simply referred to as "the vanilla". It was first scientifically named in 1808. With the species' population in decline and its habitats being converted to other purposes, the IUCN has assessed Vanilla planifolia as Endangered.
Epipogium aphyllum, the ghost orchid, is a hardy mycoheterotrophic orchid lacking chlorophyll. It is one of the rarest representatives of Orchidae family.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Asimina tetramera, commonly known as the four-petal pawpaw, is a rare species of small tree or perennial shrub endemic to Martin and Palm Beach Counties in the state of Florida. The species is currently listed as endangered under the Endangered Species Act and as endangered by the International Union for Conservation. The four-petal pawpaw is part of the family Annonaceae alongside other Asimina species.
Dendrophylax is a genus of leafless neotropical orchids native to Mexico, Central America, the West Indies, and Florida. The name is from Greek δένδρον ("tree") and φύλαξ. One species, Dendrophylax lindenii, featured heavily in the book The Orchid Thief.
Cypripedium reginae, known as the showy lady's slipper, pink-and-white lady's-slipper, or the queen's lady's-slipper, is a rare lady's-slipper orchid native to northern North America. Although never common, this plant has vanished from much of its historical range due to habitat loss. It is the state flower of Minnesota.
Vanilla polylepis is a climbing orchid species in the plant family Orchidaceae. It is native to tropical Africa, with a range spanning the width of the continent, from Kenya to Angola. It grows in high-altitude evergreen and swamp forests between 1,200–1,500 m (3,900–4,900 ft) and is often found growing on trees bordering rivers and waterfalls. Plants produce bright green, fleshy stems, 10–12 mm (0.39–0.47 in) in diameter, with large, glossy leaves. White, aerial roots form on the stems allowing the orchids to attach themselves to trees for support. As with many orchids, they produce showy flowers, which in the case of V. polylepis are white and yellow with a pink to maroon blotch. This differentiates them from similar species. They have seedpod-like fruits, called capsules, which produce a distinctive aroma as they dry. They are closely related to the well-known species Vanilla planifolia, whose seed pods are used commercially in the production of vanilla flavouring.
Spiranthes diluvialis is a rare species of orchid known as Ute lady's tresses. The species name diluvialis means "of the flood". It is native to the western United States, where there are scattered, mostly small occurrences in the states of Colorado, Idaho, Montana, Nebraska, Nevada, Utah, Washington, and Wyoming. An occurrence was recently discovered in southern British Columbia. The plant faces a number of threats to its existence. It is a federally listed threatened species of the United States.
Dendrophylax funalis, also known as the ghost orchid, is a species of epiphytic orchid that is native to the island of Jamaica.
Drymoanthus adversus is an orchid species endemic to New Zealand.
