Gongora Beyrodtiana
''Gongora'', abbreviated Gga in horticultural trade, is a member of the orchid family ( Orchidaceae). It consists of 65 species known from Central America, Trinidad, and tropical South America, with most species found in Colombia. They grow across a wide geographical range, from wet forests at sea level, to mountainous regions in the Andes, as high as 1,800 m. The name comes from Antonio Caballero y Gongora, a viceroy of New Granada (Colombia and Ecuador) and the governor of Peru during the Ruiz and Pavón botanical expedition. ''Gongora'' was one of the first orchids described by a European. Several new ''Gongora'' orchids have been discovered in the 2000s-2010s, whilst many others have been re-grouped under different classifications. Yet there is still some confusion; Many species lack "appropriate" descriptions. Some species, such as ''Gongora portentosa'' and ''Gongora superflua'', are extremely isolated in population.

Mealybug
Mealybugs are insects in the family (biology), family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pest (animal), pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector (epidemiology), vector for several plant diseases. Some ants live in symbiotic Ant#Relationships with other organisms, relationships with them, protecting them from predators and feeding off the Honeydew (secretion), honeydew which they excrete. Description Mealybugs are Sexual dimorphism, sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coeliopsidinae
Coeliopsidinae is an orchid subtribe in the tribe Cymbidieae. The three members of this subtribe have traditionally been lumped in with Stanhopeinae, but obvious morphological traits and new molecular analysis by Whitten et al. in 2000 confirmed the group reclassified by Szlachetko (1995). These genera have smooth, unribbed, ovoid pseudobulbs with 3-4 large and thin plicate leaves. The inflorescences are thick and bear globose flowers with thick, fleshy sepals and petals, presence of a column foot and mentum. Roots have prominent root hairs. Most distinct is the viscidia that are button-shaped and sclerified with short stipes. The three genera all have elongated ''Maxillaria''-type dust seeds and not ''Stanhopea''-type balloon seeds. Like Stanhopeinae the members of this group are pollinated by male euglossine bees. The sticky viscidia of this group are adapted to attachment on the smooth surface of the scutum The ''scutum'' (; plural ''scuta'') was a type of shield used ...

Stanhopeinae
Stanhopeinae is a subtribe of plants in the tribe Cymbidieae. The subtribe in the strict sense, have viscidia and stipes that are thin and strap-like, they are adapted for attachment to edge of the bee's scutellum or to a leg. Pseudobulbs are usually ribbed/four-angled or flattened. Leaves are generally thicker than Coeliopsidinae. Roots are smooth, without prominent root hairs. The column foot is lacking or not distinct. Unpollinated flowers quickly abscise and fall from the inflorescence, unlike members of Coeliopsidinae which include ''Coeliopsis'', '' Lycomormium'', and '' Peristeria''. Stanhopeinae and Coeliopsidinae are now considered closely related sister subtribes. Within Stanhopeinae the members can be further grouped in six clades based on morphological traits and molecular analysis. *''Braemia'' Clade: '' Braemia'' *''Gongora'' Clade: ''Cirrhaea'' & '' Gongora'' *''Acineta'' Clade: ''Acineta'', '' Lacaena'', ''Lueddemannia'' & ''Vasqueziella'' *''Polycycnis'' Clade: ...

Pollinium
A pollinium (plural 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 ...

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".

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] |
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] |
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 ...
