Epidendrum
''Epidendrum'' , abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family. With more than 1,500 species, some authors describe it as a mega-genus. The genus name (from Greek ''επί, epi'' and ''δένδρον, dendron'', "upon trees") refers to its epiphytic growth habit. When Carl Linnaeus named this genus in 1763, he included in this genus all the epiphytic orchids known to him. Although few of these orchids are still included in the genus ''Epidendrum'', some species of ''Epidendrum'' are nevertheless not epiphytic. Distribution and ecology They are native to the tropics and subtropical regions of the American continents, from North Carolina to Argentina. Their habitat can be epiphytic, terrestrial (such as '' E. fulgens''), or even lithophytic (growing on bare rock, such as '' E. calanthum'' and '' E. saxatile''). Many are grown in the Andes, at altitudes between 1,000 and 3,000 m. Their habitats include humid jungles, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epidendrum Calanthum
''Epidendrum calanthum'' is a terrestrial reed-stemmed ''Epidendrum'' orchid from the montane Tropical rainforest of Bolivia (including Cochabamba), Colombia, Ecuador, Peru, Venezuela, and the West Indies. Description ''E. calanthum'' shares with other members of the subgenus ''E''. subg. ''Amphiglottium'' Lindl. (1842) a sympodial habit, terete stems covered from the base with close, tubular, disthicous sheathes which are leaf-bearing on the upper part of the stem, and a terminal peduncle covered from its base with close, tubular sheathes. The stem grows to 1 m tall below the inflorescence, and the inflorescence itself grow to 0.4 m tall, with the white to pink resupinate flowers born in a congested raceme at the end. The leaves grow to 10 cm long. The oblong sepals are 9 mm long. The petals are 9 mm long and narrower than the sepals, with serulate to erose edges. The broad, lacerate lip is adnate to the column to its apex, and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidendrum Fulgens
''Epidendrum fulgens'' is a crucifix orchid native to Brazil. Like '' E. secundum'', with which it has been found to hybridize in habitats disturbed by human activity, ''E. fulgens'' flowers are non-resupinate and are born in a congested racime at the end of a long spike. Like all crucifix orchids, the lip is adnate to the column and bears three lobes, producing the effect of a cross. Like E. cinnabarinum, E. denticulatum, and E. puniceoluteum (also Brazilian members of subsection carinata), E. fulgens grows in the litoral restinga habitat. The specific epithet, ''fulgens'', is the present participle of the Latin verb ''fulgere'' "to shine, to glow" and refers to the brilliant yellow-orange flowers with red spots on the yellow lip. Distinguishing characteristics ''E. fulgens'' has a noticeably wider angle (nearly 180°) between the lateral sepals than most of the crucifix orchids, as well as a noticeably narrower angle (little more tha ...

Epidendrum Nocturnum
''Epidendrum nocturnum'' (the "nocturnal epidendrum") is the type species of the genus ''Epidendrum'' of the Orchidaceae (Orchid family). The species occurs in Florida, Bahamas, West Indies, Belize, Central America to northern Brazil and the Guyanas. ''Epidendrum nocturnum'' is common in South Florida. It is usually autogamous (flowers self-pollinate) and sometimes cleistogamous (flowers self-pollinate before they open). The haploid chromosome number of ''E. nocturnum'' has been determined as ''n'' = 20. The diploid chromosome number has been determined both as 2''n'' = 40 and as 2''n'' = 80. In 1984, the variety ''E. nocturnum'' var. ''guadeloupense'' was determined to have a diploid chromosome number of 2''n'' = 42—48. On November 7, 2010, Kew did not recognize the existence of this variety in its World Checklist of Selected Plant Families The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an ...

Orchid Family
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. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosthechea
''Prosthechea'' is a genus of flowering plants in the orchid family (Orchidaceae). The name is derived from the Greek word ''prostheke'' (appendix), referring to the appendage on the back of the column. Appendage orchid is a common name for this genus. ''Prosthechea'' is abbreviated ''Psh.'' in the horticultural trade. Morphology The roots of all ''Prosthechea'' species possess a velamen (a thick sponge-like covering) differentiated into epivelamen and endovelamen. Flavonoid crystals were observed in both the roots and leaves. The erect stems form flattened or thickened pseudobulbs. There are 1 to 3 terminal, sessile leaves. The leathery blade is ovate to lanceolate. (''Euchile'' leaves are softer and thinner than other ''Prosthechea'' leaves.) The flowers form an apical, paniculate raceme with a spathe at the base of the inflorescence. There is a great variety in the flowers of this genus. They may be attached to the stem by a peduncle or they may be sessile. They can flower on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycorrhizal
A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phos ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
