Jejewoodia
''Jejewoodia'' is a genus of flowering plants belonging to the family Orchidaceae. It is native to Borneo. Description Epiphytic herbs. Has a stem that grows up to about long which is simple or branching. It has rooting at base and is leafy. The leaves are distichous (arranged in two opposite rows), ensiform (shaped like the blade) and flattened. The inflorescence (flower) is lateral, axillary and borne from upper portion of stems. It is one-flowered (per stem), sometimes four or five flowers open simultaneously in succession per stem. The floral bracts are less than 1/8 the length of pedicel (botany), pedicel (stalk of a flower) and brownish in colour. The flowers are up to 1 cm in diameter and usually opening widely. The sepals and petals are white, less often yellow or greenish yellow. The labellum (botany), labellum (lip) is white, sometimes with a yellow central patch at base of mid-lobe. The sepals and petals are free (unattached) and spreading. The sepals are narrowly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeridinae
In the botanical classification of plants, Aeridinae Pfitzer is a subtribe of the tribe Vandeae (Family Orchidaceae) whose representatives all have a monopodial growth habit and do not possess pseudobulbs. This subtribe is a monophyletic group within Vandeae, and it contains more than 1,300 species in 103 genera, including about 208 (38%) hybrid genera. They occur mostly in Asia with a few in Africa. They are distinguished from the other subtribes of Vandeae by having an entire rostellum, a relatively small spur formed by the lip, and four (or two) pollinia. Some of the genera it contains have some of the largest and most spectacular flowers in the whole of the orchid family. Also included in this subtribe are some of the most economically important genera in the horticultural trade, such as ''Phalaenopsis'' and '' Vanda''. Leaflessness Aeridinae contains the largest diversity of leafless taxa within the tribe Vandeae. These leafless species of the genera '' Chiloschista'' ...

Vandeae Genera
The Vandeae is a large monophyly, monophyletic Tribe (biology), tribe within the family of orchids. Scope This tribe contains 1,700 - 2,000 species in more than 150 genera. Epiphytic These orchids are pantropical epiphytes and occur in tropical Asia, the Pacific Islands, Australia and Africa. Many of these orchids are horticulture, horticulturally important, especially ''Vanda'' and ''Phalaenopsis''. Subtribes This tribe is subdivided into four subtribes: *Subtribe Adrorhizinae *Subtribe Aeridinae (formerly, illegitimate subtribal name Sarcanthinae): largest subtribe with more than 1,000 species in 103 genera, including about 200 hybrid species; occurs mostly in Asia and Australia and with a few in Africa. They are distinguished from the other subtribes by having an entire rostellum, a relatively small Spur (biology), spur formed by the lip, and four (or two) pollinium, pollinia. *Subtribe Angraecinae Summerh.: about 400 species in 19 genera. They occur in tropical Africa, Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kew Gardens
Kew Gardens is a botanical garden, botanic garden in southwest London that houses the "largest and most diverse botany, botanical and mycology, mycological collections in the world". Founded in 1759, from the exotic garden at Kew Park, its living collections include some of the 27,000 taxa curated by Royal Botanic Gardens, Kew, while the herbarium, one of the largest in the world, has over preserved plant and fungal specimens. The library contains more than 750,000 volumes, and the illustrations collection contains more than 175,000 prints and drawings of plants. It is one of London's top tourist attractions and is a World Heritage Sites, World Heritage Site. Kew Gardens, together with the botanic gardens at Wakehurst Place, Wakehurst in Sussex, are managed by the Royal Botanic Gardens, Kew, an internationally important botany, botanical research and education institution that employs over 1,100 staff and is a non-departmental public body sponsored by the Department for Envir ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinia
A pollinium (: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoideae, ( ...
