    Mairie d’Andeville 1, rue Jean Jaurès 60570 Andeville www.orchidee-60.fr Compte rendu de la réunion d’association Samedi 25 mai 2019 Gérard LEUK ouvre la séance en accueillant chacun et en évoquant l’installation de l’exposition à Moncel. Il informe de la bourse aux orchidées à Ransart le 16 juin prochain et présente Jean-Yves GIL qui nous fait le plaisir de revenir nous voir. Jean-Yves GIL - les « Cambrias orchidées ornementales ». Le groupe « Cambria » est parmi les orchidées celui qui a été le plus vulgarisé avec les Phalaenopsis sur le marché des jardineries, des leuristes et devenu accessible à tous. Pour Jean-Yves l’appellation Cambria est erronée telle qu’elle est utilisée. Le nom Cambria provient d’un hybride d’exception : Vuylstekeara Cambria qui fut enregistré en 1031 par Charlesworth Ltd, en Angleterre, dont le cultivar « Plush » a obtenu les plus hautes récompenses internationales dans les expositions. C’est un hybride tri-générique (Odontoglossum x Cochlioda x Miltonia). Il connu un grand succès populaire dans les années 1975 -1990 par la démocratisation des orchidées en général. Le nom de Cambria s’est trouvé associé à tous les hybrides ayant des caractéristiques communes avec lui. Si l’on décrit un Cambria : on peut dire de lui de façon générique, qu’il a : - une croissance sympodiale, les pseudobulbes sont successifs et ovoïdes, de longues feuilles rubanées vert clair, des racines longues et fines ; - La taille varie en fonction des parents utilisés au cours des croissements successifs ; elle mesure de 20 à 40 cm, voire plus pour certains dont les hampes peuvent atteindre 1m ; - Les fleurs sont plutôt étoilées avec un labelle ondulé à frisoté.

    Orchid of the Month for June, 2015 Oncidium Longipes by Bruce Adams

    Orchid of the Month for June, 2015 Oncidium Longipes by Bruce Adams Figure 1: Oncidium longipes When I first fell in love with orchids, about forty years ago, Oncidium was my favorite genus. I loved the intricate flowers on long sprays, often with a wonderful fragrance. At that time, I worked as a volunteer in the orchid house at Planting Fields Arboretum. After repotting plants, I had the opportunity to take home back bulbs, and received pieces of Oncidium sphacelatum, O. flexuosum, and others that I can no longer remember. Every year they had an orchid auction, and for the extravagant price of five dollars, I purchased a multi-lead plant of O. ornithorhyncum. I became familiar with many of the various species, and at the time was a bit of an Oncidium expert. Forty years later, I’ve forgotten much, and with the recent changes in nomenclature maybe I wasn’t ever really an Oncidium expert, but rather a Trichocentrum, Gomesa, and Tolumnia expert! What hasn’t changed is my fondness for this vast genus (or group of genera). Plants can get quite large, such as Oncidium sphacelatum, which can easily can fill a twelve-inch pot, sending out three foot spikes with hundreds of flowers. But there are also miniatures like Oncidium harrisonianum, which can be contained in a three or four inch pot and sports short sprays of pretty little yellow flowers with brown spots. In fact, most Oncidium flowers are a variation of yellow and brown, although Oncidium ornithorhyncum produces pretty purple pink flowers, while Oncidium phalaenopsis and its relatives have beautiful white to red flowers, often spotted with pink.

China 3 Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun Township, Mengla County, Yunnan province 666303, P.R. China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice.

Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.

    Orchids: 2017 Global Ex Situ Collections Assessment

    Orchids: 2017 Global Ex situ Collections Assessment Botanic gardens collectively maintain one-third of Earth's plant diversity. Through their conservation, education, horticulture, and research activities, botanic gardens inspire millions of people each year about the importance of plants. Ophrys apifera (Bernard DuPon) Angraecum conchoglossum With one in five species facing extinction due to threats such (Scott Zona) as habitat loss, climate change, and invasive species, botanic garden ex situ collections serve a central purpose in preventing the loss of species and essential genetic diversity. To support the Global Strategy for Plant Conservation, botanic gardens create integrated conservation programs that utilize diverse partners and innovative techniques. As genetically diverse collections are developed, our collective global safety net against plant extinction is strengthened.

(Phalaenopsis Joane Kileup June, Phalaenopsis Pinlong Cinderella, and (Phal. Fortune Buddha x Phal.

The crossing of Phalaenopsis sp. and Vanda tricolor was compatible, and the use of Phalaenopsis sp. as male parent had better probability in producing fruits rather than the opposite. The crossing which was done at the first and the second weeks after blooming produced more fruit than the crossing at the third week after blooming, even though it did not affect the success of crossing, time of fruit formation, and duration of fruit hanging.

  • Pollinator Specificity and Seasonal Patterns in the Euglossine Bee-Orchid Mutualism at La Gamba Biological Station

    Pollinator Specificity and Seasonal Patterns in the Euglossine Bee-Orchid Mutualism at La Gamba Biological Station

    Acta ZooBot Austria 156, 2019, 171–181 Pollinator specificity and seasonal patterns in the euglossine bee-orchid mutualism at La Gamba Biological Station Santiago R. Ramirez The plant family Orchidaceae exhibits some of the most spectacular and intricate ad- aptations for insect pollination. Across the Neotropical region male euglossine bees provide pollination services to approx. 700 orchid species that have evolved scent pro- duction in exchange for sexual reproduction. Male orchid bees collect scents from flowers and other sources to concoct perfume mixtures that they use as pheromone analogs during courtship display. Although the pollination biology of some of these associations has been studied in detail for some orchid taxa, community-wide analyses of this mutualism are lacking. Here I present an analysis of the plant-pollinator affilia- tion patterns and phenology among scent-producing orchids and male euglossine bees based on 960 bee-orchid interactions obtained over the course of five years of sampling at La Gamba Biological Station (south-western Costa Rica). I identify a highly nested plant-pollinator network that is composed of 24 bee species and 17 orchid genera. Some orchid genera exhibit pronounced flowering seasonality, with most of the diver- sity of interactions taking place during the dry season (March-April) and few orchid taxa blooming throughout the year. The architecture of the plant-pollinator network also revealed a substantial degree of pollinator sharing among orchid genera, suggest- ing that distantly related lineages independently converged on the use of similar pol- linator bee assemblages.

    Chapter 23 Phalaenopsis Chia-Chi Hsu, Hong-Hwa Chen, and Wen-Huei Chen Abstract Phalaenopsis is one of the most popular cultivated orchids worldwide. So far, 92 native species and 34,112 hybrids of Phalaenopsis have been registered in the Royal Horticultural Society (RHS), but only 18 native species are frequently used for breeding. In Phalaenopsis market, large flowers with various colors are most popular. Phal. amabilis and Phal. aphrodite are the major species used for breeding the white-and-large-flower hybrids. The colored hybrids include pink, red- to- purple, green, yellow-to-orange, and black colors, as well as distinct colors in tepals with red lip. For large-and-red flowers,Phal. schilleriana and Phal. sanderiana are the major parent species, whereas Phal. equestris and Phal. pulcherrima are important for the development of the small- and medium-sized red flowers. Members of the subgenusPolychilos are the most important ancestors for yellow-to-orange flowers. More recently, there is an increased interest in plants with white, pink, or yellow colors with red stripes and/or spots. These traits are introduced from Phal. lindenii, Phal. stuartiana, and Phal. amboinensis. Furthermore, harlequin flowers which have clown-like spots and very complicated color patterns are released in the market, as well as hybrids with peloric and Bigfoot flowers. Besides color, scent and (a)biotic stress resistance are becoming important targets in Phalaenopsis breeding. Keywords Bigfoot · Breeding · Harlequin · Orchids · Peloric · Phalaenopsis C.-C.
