× Potinara
× ''Potinara'', abbreviated Pot in the horticultural trade, is the nothogenus comprising those intergeneric hybrids of orchids which have '' Brassavola'', ''Cattleya'', ''Laelia'' and ''Sophronitis'' as parent genera. It can easily be imagined that a combination of all the desirable qualities of the four genera would be an outstandingly handsome thing. However, plants in which all the desired qualities show up occur in only a small proportion of the offspring, and the percentage of plants homozygous for all qualities even less often. A rather extensive breeding program would be necessary to achieve the ideal results. Many lovely combinations do occur in × ''Potinara'' crosses, although relatively few have been made. The search for a way to breed large red hybrids has been given a new boost with the discovery of '' Cattleya milleri''. It is hoped that this species will not offer the genetic difficulties that have plagued hybridists using ''Sophronitis''. Some encouraging resu ...

Plantae
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Cattleya
''Cattleya'' () is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals. Description Epiphyte, Epiphytic or terrestrial orchids with cylindrical rhizome from which the fleshy noodle-like roots grow. Pseudobulbs can be conical, spindle-shaped or cylindrical; with upright growth; one or two leaves growing from the top of them. The leaves can be oblong, lanceolate or elliptical, somewhat fleshy, with smooth margin. The inflorescence is a terminal raceme with few or several flowers. Flowers have sepals and petals free from each other; the Labellum (botany), lip or labellum (lowermost petal), usually has a different coloration and shape from the rest of the flower and covers in part the Column (botany), flower column forming a tube. There are four pollinia (bag-like organs that contain pollen). The fruit is a capsule with many small seeds.Schweinfurth, C., "Orchidaceae, Orchids of Peru", ''Fieldiana, Botany'' 30(3): 535 Taxonomy The ...

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] |
Rhyncholaelia
''Rhyncholaelia'', abbreviated ''Rl.'' in the horticultural trade, is a genus of orchids (family Orchidaceae), comprising two species. They are distributed in Mexico, Guatemala, Belize, and Honduras Honduras, officially the Republic of Honduras, is a country in Central America. It is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, .... Both species were originally published in '' Brassavola'' by Lindley. In 1918, Schlechter erected the new genus ''Rhyncholaelia'' and moved ''Brassavola digbyana'' Lindl. 1846 and ''Brassavola glauca'' Lindl. 1839 into it.Beihefte zum Botanischen Centralblatt (in German) (2nd ed.).

Guarianthe
''Guarianthe'', abbreviated ''Gur.'' in the horticultural trade, is a small genus of epiphytic orchids, growing in wet forests in Mexico, Central America, Colombia, Venezuela and Trinidad. It was separated from the bifoliate ''Cattleya''s in 2003, based on phylogenetic studies of nuclear DNA sequence data.
