  • 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.

  • Bulbophyllum
    Bulbophyllum Introduction ::: Bulbophyllum are the largest genus in the orchid family with species deriving from the high and low altitude rain and cloud forests of most tropical and subtropical countries. They have tremendous variation in their growth habit, ranging from fully terrestrial species to giant epiphytic climbers. They can bloom directly from the rhizome or the growth, depending on the species. Whilst it seems they are a diverse group of plants, they can mostly be grown together. They are a good genus to cultivate and relatively forgiving. Pot type: These orchids can be grown mounted on slabs of cork or tree fern. However, all the species can be grown in shallow pots, or even baskets. One requirement is to retain enough moisture at the root, as most species don’t like to dry out. The rhizome can be trained to stay in the pot by bending them, eventually cutting the old bulbs and leaving them in place, so they will provide additional growth in the pot. Sphagnum has been popular because it retains a lot of moisture, which is what these plants prefer when in active growth; however when it decays or starts to retain too many salts, the plants will have problems. One common problem being rot, for some more sensitive species, sphagnum will have a too low pH, resulting in either rhizome or emerging growth rot. Growers then start to keep the sphagnum dryer to prevent the rot, but it precludes a strong, fast growth. Orchiata has a higher pH, retains enough moisture and due to Orchiata’s longevity there is no need to disturb the plant for some years.

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.

    Nambour Orchid News FebruaryMay 2018 2018 Judges Choice - April - Bulbophyllum medusae. This species is epiphytic and lithophytic. It grows on limestone rocks in Thailand, western Malaysia, the islands of Sumatra and Borneo, Singapore, and the Philippines. I purchased this plant from Robert Trost at our Species Show in November 2011. It had three pseudobulbs growing in an 80mm pot, and sat and sulked for a year before starting to grow. It flowered for the first time in April 2014 with two inflorescences. May 2016, eight inflorescences, and later that year was potted up into the current size saucer, 260 x 50 mm. The plant has doubled in size since then. It is growing in a mixture of perlite and peat at a ratio of 12-1 with small amounts of medium bark, charcoal, diatomite and coconut pieces, with some gravel on top. It is under 70 percent shadecloth during summer, with a layer of solar weave added for winter. Watering is done to suit weather conditions, every second or third day in warmer weather, in cold conditions about once a week. I use a small amount of Plantacote Top K controlled release fertiliser twice a year, and use various foliar fertilisers at half strength every two weeks. Once a month I use a systemic fungicide, next month contact insecticide, following month contact fungicide, then systemic insecticide. Mid April the plant had four inflorescences open, but still lots of buds. Then, with good timing, two days before our meeting, nineteen inflorescences opened. At the meeting, a panel of judges considered the plant for an award, and it received an HCC and ACC.

A group of 20 plus diehard SGAP enthusiasts met at the trailhead and undertook the walk of approximately 3 km one way. With the first 2.1 km easy going, the balance is a strenuous climb to an elevation of around 1,100 metres. II I1 Moving from the main track to the Major's Mountain goat trail, the orchids started with a Plectorrhiza tridentata and several Bulbophyllurns. Shortly after the steep climbing starts the orchid zone is reached. The pace slowed considerably as everyone explored this wonderful orchid habitat, and the difficulty of the walk faded away. Dendrobium adae in bloom greeted the walkers; some flowers with a significant amount of red on the back of the tepals caught the interest of several people. Amongst the orchids in bloom visible at eye level was Sarcochilusfalcatus. The plants are small with flowers nearly as large as the plants. A stunning Sarcochilus borealis (olivaceous) on a tree trunk barely 100 mm off the ground tested the determination of several photographers. (Mind you the ground was sloping up at over 50°.*) Several plants of Taeniophyllum were found carrying seed pods, but without the flowers positive identification of the species was not possible.

  • Movements of Floral Parts and Roles of the Tooth On
    Journal of Pollination Ecology, 24(17), 2018, pp 157-163 — Short Communication — MOVEMENTS OF FLORAL PARTS AND ROLES OF THE TOOTH ON THE COLUMN WALL OF BULBOPHYLLUM PRAETERVISUM (ORCHIDACEAE) FLOWER IN POLLINATION BY DACINI FRUIT FLIES (DIPTERA: TEPHRITIDAE) Tan, Keng Hong*1,2 and Tan, Lin Tze3 1Mobula Research Sdn. Bhd., 20, Jalan Tan Jit Seng, 11200 Penang, Malaysia 2Academy of Sciences Malaysia, MATRADE Tower, Jalan Sultan Haji Ahmad Shah, 50480 Kuala Lumpur, Malaysia 3Bachemer Strasse, 20, Bonn, 53179 Germany Abstract—Bulbophyllum is the largest genus of the orchid family, with about 2000 species that are mainly pollinated by flies. Flowers of many Bulbophyllum species under the Sections Sestochilos and Beccariana specifically attract Dacini fruit flies, Bactrocera and Zeugodacus species, as pollinators. Non-nectar producing and non-resupinate solitary flowers of Bu. pratervisum emit specific and pleasant floral fragrances to specifically attract and reward male fruit flies. Slippery surfaces on their lateral sepals aid in pollination. Although pollinia removal by male fruit flies has been observed frequently, deposition of pollinia to complete pollination (by two males of Ba. albistrigata and Z. caudatus) has only been observed recently. Field observations show two previously unreported movements of floral parts – a) petals and medial sepal during daily closing and reopening of flowers, and b) the spring-loaded and hinged lip during removal and deposition of pollinia by a male fruit fly. Additionally, a third (novel) movement has been observed, either when the flower closes for the night to protect the stigma, or after a fly has deposited the pollinia onto the stigma, the 'acute tooth' on each column wall folds inwards specifically to secure the newly deposited pollinia.
