× Cattlianthe
× ''Cattlianthe'', abbreviated ''Ctt.'' in the horticultural trade, is the Orchidaceae, orchid nothogenus for intergeneric hybrid grex (horticulture), greges containing at least one ancestor species from each of the two ancestral genera ''Cattleya'' and ''Guarianthe'', and from no other genera. Since orchids in ''Guarianthe'' were placed in ''Cattleya'' before 2003, many orchids in × ''Cattlianthe'' were previously placed directly in ''Cattleya''. Notable hybrids Notable hybrids, known as Grex (horticulture), greges, include the following: * ''Ctt.'' Jewel Box (formerly ''Slc''. Jewel Box), a Hybrid (biology), hybrid cross of ''Guarianthe aurantiaca'' and ''Cattleya'' Anzac. Its bifoliate pseudobulbs are about 4" tall and grow along a horizontal rhizome. A terminal inflorescence is produced from a sheath at the tip of newly matured pseudobulbs. ''Ctt''. Jewel Box averages 4.8 flowers per inflorescence and 9.2 cm (3.6 inches) natural spread. Flowers are slightly cupped, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
× Sophrolaeliocattleya
× ''Sophrolaeliocattleya'' (from ''Sophronitis'', ''Laelia'' and ''Cattleya'', its parent genera) is a Hybrid name, nothogenus of artificial intergeneric orchid Hybrid (biology), hybrids. It is abbreviated as Slc. in the horticultural trade. As of 2008, × ''Sophrolaeliocattleya'' is defunct, with the genus ''Sophronitis'' having been merged into ''Cattleya''. Anatomy, morphology and habit × ''Sophrolaeliocattleya'' often shows the influence of its ''Sophronitis'' parent strongly; its flowers tend to range through yellow-orange to red, they tend to be smaller, and the general habit (biology), habit of the plant tends to be comparatively compact, all characteristics shared with ''Sophronitis''. Etymology and taxonomic history This nothogenus, nothogeneric epithet is derived by putting together the component genera: ''Sophronitis'' (combining form -), ''Laelia'' (combining form -) and ''Cattleya''; it is capitalized and is not italicized because it is a nothogeneric epith ...

Pseudobulbs
In botany, a pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed ''heteroblastic'' and ''homoblastic'' respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length.Hew, C.S., and J.W.H. Yong. 2004The Physiology of Tropical Orchids in Relation to the Industry.Singapore: World Scientific Publishing Co. pp. 13-15. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales.Dressler, R.L. 1993.

Cattleya Labiata
''Cattleya labiata'', also known as the crimson cattleya or ruby-lipped cattleya, is the type species of ''Cattleya'', discovered in 1818 in Brazil. Description This plant grows in the northeastern area of Brazil, in the states of Pernambuco and Alagoas. They grow to different sizes depending on the area from which they originate. Those that are growing in Pernambuco are smaller, with small but colored flowers, with most of them being lilac. The interior part of the flower is a dark lilac color. Plants from Alagoas are bigger and have larger flowers. Some varieties, such as ''Cattleya labiata'' var. semialba, have large white flowers with a touch of yellow. There is another variety of semialba, with lilac in the inferior part of the flower. This plant is an epiphyte, growing up in trees, where light is plentiful. However, there are also many other places where this plant could grow, such as directly on rock with very little soil. The plant itself is a medium-sized unifoliate (la ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizome
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and Shoot (botany), shoots from its Node (botany), nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guarianthe Aurantiaca

Orchidaceae
Orchids are plants that belong to the family (biology), family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan distribution, cosmopolitan plants that are found in almost every habitat (ecology), habitat on Earth except glaciers. The world's species richness, richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae 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 (genus), Vanilla'' (the genus of the Vanilla planifolia, vanilla plant), the type genus ''Orchis'', and many commonly cultivated plants s ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Grex (horticulture)
The term ''grex'' (plural ''greges'' or ''grexes''; abbreviation gx), derived from the Latin language, Latin noun , , meaning 'flock', has been expanded in botanical nomenclature to describe hybrids of orchids, based solely on their parentage. Grex names are one of the three categories of plant names governed by the International Code of Nomenclature for Cultivated Plants; within a grex the ''cultivar group'' category can be used to refer to plants by their shared characteristics (rather than by their parentage), and individual orchid plants can be selected (and propagated) and named as cultivars. Botanical nomenclature of hybrids The horticultural nomenclature of grexes exists within the framework of the botanical nomenclature of hybrid plants. Interspecific hybrids occur in nature, and are treated under the International Code of Nomenclature for algae, fungi, and plants as nothospecies, ('notho' indicating hybrid). They can optionally be given Linnean Binomial nomenclature, bin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
