Vanda
''Vanda'', abbreviated in the horticultural trade as ''V.,'' is a genus in the orchid family, Orchidaceae. There are about 87 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers.The Orchids, Natural History and Classification, Robert L. Dressler. ''Vanda'' species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific. Biology The name "Vanda" is derived from the Sanskrit (वन्दाका) name for the species ''Vanda roxburghii'' (a synonym of ''Vanda tessellata''). These mostly epiphytic, but sometimes lithophytic or terrestrial orchids, are distributed in India, Himalaya, Southeast Asia, Indonesia, the Philippines, New G ...

Orchidaceae
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] |
Pneumatode
In botany, pneumatodes are air-containing structures in plant roots. Their function is to allow gaseous exchange in root tissues. This can be beneficial to semi-aquatic plants, such as neo-tropical palms. Plants with photosynthetic roots, such as epiphytic orchids like ''Dendrophylax lindenii'' also possess these structures. They play a role in fungal interactions. Etymology The name of the structure is derived from the Greek word πνεῦμα (pneûma), meaning breath and ὁδός (hodós), meaning pathway. Fungal interactions Fungal infections of plants may begin through penetration of the roots through pneumatodes. Functional analogy to stomata Pneumatodes are considered as a special type of cyclocytic stomata. The entire structure may rise above the adjacent epidermis. The pneumatodes may function as double structures for gas exchange and liquid water elimination (guttation). Leafless orchids with photosynthetic roots rely on the gas exchange through pneumatodes for phot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gaud
Gaur Brahmins (spelling variations: Gor or Gour), also Gauda Brahmins (spelling variations: Gaud, or God), also known as Adi Gauda/Gaur, is a group of Brahmin communities in India. The Gauda Brahmins are one of the five Pancha Gauda Brahmin communities that lives in the north of the Vindhyas. Gaur Brahmins likely originated from Kurukshetra region. Initially inhabiting tracts of land between the Yamuna and Sutlej rivers. Today they are most numerous in the western half of Northern India, particularly in the states of Haryana, Punjab, Rajasthan as well as in the western parts of Uttar Pradesh and Madhya Pradesh and a significant amount are present in other northern states of India as well. The Gaurs claim that the other four main divisions of North Indian Brahmins were originally Gaur, and have acquired their present designations of Saraswat Brahmins, Kanyakubja Brahmins, Maithil Brahmins and Utkala Brahmins by immigrating to the provinces where they are now domiciled.

Monopodial
Vascular plants with monopodial growth habits grow upward from a single point. They add leaves to the apex each year and the stem grows longer accordingly. The word ''Monopodial'' is derived from Greek "mono-", ''one'' and "podial", "foot", in reference to the fact that monopodial plants have a single trunk or stem. Orchids with monopodial growth often produce copious aerial roots that often hang down in long drapes and have green chlorophyll underneath the grey root coverings, which are used as additional photosynthetic organs. They do not have a rhizome or pseudobulbs so species adapted to dry periods have fleshy succulent leaves instead. Flowers generally come from the stem between the leaves. With some monopodial species, the stem (the rhizome) might fork into two, but for all monopodial orchids this is not necessary for continued growth, as opposed to orchids with sympodial growth.''The Orchid Expert'', Dr. D. G. Hessayon David Gerald Hessayon OBE (born 1928) is a British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
