The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

Bifoliate Cattleyas - Cattleya Tigrina (Syn
St. Augustine Orchid Society www.staugorchidsociety.org Bifoliate Cattleyas - Cattleya tigrina (syn. leopoldii) by Sue Bottom, [email protected] If your orchids do not bloom much during the heat of the summer, you might consider adding some bifoliate cattleyas to your collection. There are small varieties like Cattleya walkeriana, aclandiae and violacea that do not take up too much space and bloom several times a year. Then there are the large varieties like Cattleya tigrina, which was called leopoldii for years. It has beautiful clusters of flowers held on stems above the foliage. Courtney describes these bifoliates as multiflora cattleyas in his book American Cattleyas: A multiflora cattleya is one where the inflorescence is the focus of hybridizing instead of the individual flower. Typically there are more than seven flowers on a single inflorescence arranged as a mass instead of as a series of individual flowers. While the parent species are usually bifoliate, not all bifoliates are multifloras… Multifloras are separated from all other groups discussed because the form of each individual flower, although important, is not the focus of the hybrid. The perfect multiflora cattleya has a mass of flowers with each flower fully open and barely coming in contact with other flowers in the inflorescence so that from all sides there are no large gaps between flowers. The form of each individual flower should be as closed (petals and sepals overlapping) as possible, given the parentage. The arrangement of flowers on the stem is more important than individual flower form. The typical color form of Cattleya tigrina (syn. -

Crippling American Cattleyas–
Crippling A Genetic issue in Yellow and Art-Shade Cattleyas And an update of primary hybrids associated with American Cattleyas – Species and Outstanding Clones that Defined American Hybridizing Emphasis on Primary Grexes In the June 2010 issue of Orchids, Ron Midgett discussed the little mention (but well known) issue of crippling, a genetic problem, in yellow and art-shade Cattleyas. It was the bane of efforts to breed good nonfading yellow cattleyas because the parents with the best color crippled. Crippling, which caused a thickening of tissue in the petal, became worse with age (the older the plant, the worse the crippling). It would start as a slightly thickened line of tissue running more or less parallel to the long axis of the petal. It is thought that this tissue was an attempt to create another stamen because in the worst cases a knob of tissue would form at the distal end of the thickened tissue. Inside this knob, one could usually find poorly formed but unmistakable pollinia. In the two pictures of Rhyncholaeliocattleya Golden Queen ‘Regina’ (Golden Crown x C. Miguelito), one shows a flower without crippling and the second, taken at a later blooming, show's severe crippling. This disfigurement of the flower was disheartening. Crippling is a genetic problem and continues in future bloomings, it is NOT sporadic (such as cultural related deformities). C. dowiana ‘Amanda Sofia’ AM/AOS It is generally Apr 2016, NS 11.5 x 16.2 cm accepted that the crippling gene came from the use of a particular clone of Cattleya dowiana (hort. -
The Genus Encyclia (Hooker, Bot. Mag. 55: T. 2831 [1828]) Type: Encyclia Viridiflora [En-SEE-Clee-Ah Vi-Rid-I-FLOR-A]
The Genus Encyclia (Hooker, Bot. Mag. 55: t. 2831 [1828]) Type: Encyclia viridiflora [en-SEE-clee-ah vi-rid-i-FLOR-a] There are 183 species and 16 natural hybrids (OrchidWiz [update Sep 2017]) that are mostly epiphytes that can be separated into two subgenera (not widely accepted but culturally convenient). Members of the subgenus Encyclia are principally found in seasonally dry forest at elevations from sea level to 1000 meters, while members of the subgenus Osmophytum are found in wet forest from sea level to 3,000 meters. Encyclias are distributed throughout the tropical Americas (including the West Indies, see distribution map below) with the center of distribution being in Mexico. These plants are highly variable, clump-forming, evergreen with the genus characterized by the presence of pseudobulbs; the apical inflorescence; the flowers not exceeding four centimeters in diameter; the lip free from the column for most of its length; the column without a foot; and the four hard pollinia attached to caudicles. The slender, often multibranched, numerous to few-flowered inflorescence, borne from the stem tip, has showy, wonderfully fragrant flowers found in a wide range of colors and shades of yellow, brown, green or rare pink. The flowers have similar sepals and petals. The widely varied, Encyclia viridiflora entire or trilobed lip encircles the stout or slender, footless column, but is never fully attached. These plants are best mounted on branches or tree fern plaques and generally do best in intermediate conditions. Encyclia is part of the Cattleya alliance and is often used in Cattleya alliance breeding. -
Influence of Different Concentrations of Jasmonic Acid on in Vitro Development of Catasetum Fimbriatum Lindl

This study aimed to analyze the in vitro development of Catasetum fimbriatum under different concentrations of jasmonic acid in Murashige & Skoog culture medium compound of ½ macronutrients. After 180 days of cultivation, concentration of 0.25 and 0.50 μL • L-1 caused a significant increase in number of roots and leaves. The concentration of 1.00 μL • L-1 showed the best result for the length of longest root and largest leaf, the total length of seedling, and the total fresh and dry masses. Nevertheless, the use of this plant regulator on in vitro culture media still requires further investigations to determine the optimal concentration in order to obtain desirable phytotechnical characteristics in different orchid species.

Blue Cattleyas by Courtney Hackney

It was a seedling from Stewart Orchids carefully nurtured until two big buds emerged from the sheath. As a naïve teenager working weekends at an orchid nursery, I could not wait to get back the following Saturday to see a blue cattleya.
