Lycaste Mathiasiae
''Lycaste'', abbreviated as Lyc. in horticultural trade, is a genus of orchids that contains about 30 species with egg-shaped pseudobulbs and thin, plicate (pleated) leaves. Description ''Lycaste'' flowers, like all orchid blooms, have three petals and three sepals. The petals are typically yellow, white, or orange, and the sepals are yellow, orange, green, or reddish brown. The petals and sepals may be marked sparsely or densely with red, reddish purple, purple, or reddish brown spots. The lip (ventral petal) may be very similar to the other two petals, as in ''Lycaste aromatica'' or ''Lycaste brevispatha'', or colored quite distinctively, as in several subspecies and varieties of '' Lycaste macrophylla''. Most ''Lycaste'' flowers are medium in size, averaging about 5 to 10 cm, but ''Lycaste schilleriana'' is 16–18 cm across. Some ''Lycaste'' blooms have a unique fragrance - the scent of ''Lycaste aromatica'' has been variously described as cinnamon or clove. ...

Lycaste Skinneri
''Lycaste skinneri'', also known as ''Lycaste virginalis'', is a species of epiphyte Orchidaceae, orchid that resides in the south of Mexico, Guatemala, El Salvador and Honduras, at an average altitude of 1650 meters above sea level. Description Long leaves grow from its thick pseudobulbs. The flowers of this species -generally individual- are triangular and grow from the base of the youngest pseudo-bulb and measure between 10 and 15 Centimetre, centimeters. They can vary from being completely white in the Alba variety, passing from different tones of pink to Lavender (color), lavender. This purity in color makes them the best candidate as a starting point for ''Lycaste'' Hybrid (biology), hybrid formation. The flower's blooming period is between November and April, with its peak being in the end of January and the beginning of February. A mature plant can produce between 4 and 12 flowers during the time of its blooming, which lasts between 6 and 8 weeks. It is a hermaphrodite pl ...

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".

Spine (botany)
In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called ''spinose teeth'' or ''spinose apical processes''), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. Description In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived shoots (so that they may or may not be branched, they may or may not have leaves, and they may or may not arise from a bud),Simpson, M.

Dormancy
Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase ''before'' the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase ''after'' adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are ...

Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called abscissio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumpers And Splitters
Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is a person who assigns examples broadly, assuming that differences are not as important as signature similarities. A "splitter" is one who makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was by Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: ''It is good to have hair-splitters & lumpers''. They were introduced more widely by George G. Simpson in his 1945 work ''The Principles of Classification and a Classification of Mammals''. As he put it: A later use can be found in the title of a 1969 paper "On lumpers and splitters ..." by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...
