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. -

Morphological characterization and analysis of conserved sequences of genomic DNA are frequently employed in the identification and study of fungi diversity. However, phytopathogenic Rhizoctonia-like fungi have been reliably and accurately characterized and identified through the examination of the fatty acid composition. To evaluate the efficacy of fatty acid composition in characterizing and identifying Rhizoctonia-like mycorrhizal fungi in orchids, three Epulorhiza spp. mycorrhizal fungi from Epidendrum secundum, two unidentified fungi isolated from Epidendrum denticulatum, and a phytopathogenic fungus, Ceratorhiza sp. AGC, were grouped based on the profile of their fatty acids, which was assessed by the Euclidian and Mahalanobis distances and the UPGMA method. -
Prosthechea Green Hornet
ORCHIDS WE SHOULD ALL GROW by Roy Kreugor PROSTHECHEA GREEN HORNET This particular little gem is a primary hybrid of two well known and loved “cockle shell” orchids, cochlea and lanceifolia. The family tree is a little more complicated with name changes in mid stream. First members of the Epidendrum family, this group was moved to the Encyclia heading when epis and encyclias were split. Later, the separate genus Prosthechea was created for the “cockle shell” type orchids. Today, there are about 100 species in this group, found mostly form Florida to Brazil. The plants are sympodial and mostly epiphytes. The distinction all carry is the shell shaped lip, often striped like a cockle shell, and always found at the top of the flower. Green Hornet is a primary hybrid (first generation cross of two species) of Psh cochlea X Psh lancefolia. It is an easy plant to grow in cultivation, easier than either parent. It takes its shape and size from cochlea, and its color, green form lancefolia. Plants can grow to 24” when mature with a typical size of 12-18”. Flowering season is spring to fall, although some will flower almost continuously. Flowers are borne on slender inflorescences up to 18”tall with 4-12 individual flowers opening almost simultaneously. Flowers are typically 3-4”long with narrow pedals and sepals and a shell shaped striped lip. The lip is a dark maroon on the outer side with a cream inner side striped with fine maroon markings. Pedals and sepals are a light green. Each bloom lasts from several weeks to a month. -

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind. -

The aim of this study was to examine the hypothesis that plants with higher ploidy levels are selected by environments under more extremely stressful conditions than the same (or closely related) species from less rigorous terrestrial or epiphytic habitats. Therefore, we analyzed the chromosome numbers of 26 species belonging to 21 genera and 13 families of angiosperms that were collected on 4 inselbergs in Paraiba State, northeastern Brazil. In addition, 13 rupicolous species that grow in the study area, whose chromosome numbers were previously determined, were included in our analysis. Plant chromosome numbers varied between 2n = 12 in Callisia filiformis (Commelinaceae) to 2n = ca. 240 in Epidendrum cinnabarinum (Orchidaceae). The data as a whole do not support the hypothesis that inselberg species have greater levels of ploidy than terrestrial or epiphytic populations of the same or closely related Genetics and Molecular Research 13 (4): 8353-8366 (2014) ©FUNPEC-RP www.funpecrp.com.br S.R.

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. -

Studies addressing chromosome variations have elucidated many points regarding the taxonomy of the Orchidaceae. Epidendrum L. besides being one the largest orchid genera, present remarkable morphological, and inter- and intraspecific chromosome variations. Thus, based on a previous report on flower color variation in individuals of E. ibaguense (magenta, pink, white, and red), our aim was to determine its chromosome number and test whether this trait is associated with flower color variation in natural populations on the Tepequém’s Tepuy, Roraima. Root apices were pre-treated with 8-hydroxyquinoline at 4°C for 24 h and subsequently submitted to conventional cytogenetic procedures. Slides with the best spreading and contraction of chromosomes were photographed under light Genetics and Molecular Research 16 (3): gmr16039754 S.R.
