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. -
Phylogenetic Placement of the Enigmatic Orchid Genera Thaia and Tangtsinia: Evidence from Molecular and Morphological Characters
TAXON 61 (1) • February 2012: 45–54 Xiang & al. • Phylogenetic placement of Thaia and Tangtsinia Phylogenetic placement of the enigmatic orchid genera Thaia and Tangtsinia: Evidence from molecular and morphological characters Xiao-Guo Xiang,1 De-Zhu Li,2 Wei-Tao Jin,1 Hai-Lang Zhou,1 Jian-Wu Li3 & Xiao-Hua Jin1 1 Herbarium & State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R.

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. -
Generic and Subtribal Relationships in Neotropical Cymbidieae (Orchidaceae) Based on Matk/Ycf1 Plastid Data
LANKESTERIANA 13(3): 375—392. 2014. I N V I T E D P A P E R* GENERIC AND SUBTRIBAL RELATIONSHIPS IN NEOTROPICAL CYMBIDIEAE (ORCHIDACEAE) BASED ON MATK/YCF1 PLASTID DATA W. MARK WHITTEN1,2, KURT M. NEUBIG1 & N. H. WILLIAMS1 1Florida Museum of Natural History, University of Florida Gainesville, FL 32611-7800 USA 2Corresponding author: [email protected] ABSTRACT. 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. KEY WORDS: Orchidaceae, Cymbidieae, Maxillariinae, matK, ycf1, phylogenetics, Camaridium, Maxillaria cacaoensis, Vargasiella Cymbidieae include many of the showiest align nrITS sequences across the entire tribe was Neotropical epiphytic orchids and an unparalleled unrealistic due to high levels of sequence divergence, diversity in floral rewards and pollination systems. and instead to concentrate our efforts on assembling Many researchers have posed questions such as a larger plastid data set based on two regions (matK “How many times and when has male euglossine and ycf1) that are among the most variable plastid bee pollination evolved?”(Ramírez et al. 2011), or exon regions and can be aligned with minimal “How many times have oil-reward flowers evolved?” ambiguity across broad taxonomic spans. -
The Structure and Robustness of an Epiphyte - Phorophyte Commensalistic
1 The structure and robustness of an epiphyte - phorophyte commensalistic 2 network in a neotropical inselberg 3 4 Abstract 5 Ecological networks describe the interactions between species, the underlying structure of 6 communities, the function and stability of ecosystems. To date, network analyses have been 7 extensively applied to understand mutualistic and antagonistic interactions, but few have 8 examined commensal interactions, particularly in neotropical regions. The inselbergs of 9 southeastern Brazil are considered one of the three most important regions in the world in 10 terms of terrestrial species diversity and endemism but are poorly studied. In this study, we 11 constructed the first epiphyte-phorophyte commensalistic network in a Brazilian inselberg 12 and examined its structure and robustness to simulated species loss. A total of 138 13 phorophyte individuals belonging to eight species were observed in 20 2 m × 50 m transects, 14 interacting with 5,039 individuals of vascular epiphytes belonging to 85 species. The 15 epiphyte-phorophyte network structure exhibited a low degree of specilization (H2’), low 16 connectance and robustness; when the most connected phorophyte species were sequentially 17 removed the number of secondary extinctions was high, based on robustness metrics. One 18 generalist phorophyte, Pseudobombax sp. nov., was particularly important, hosting a high 19 number of epiphyte species. A single phorophyte individual of Pseudobombax supported 20 46% of the total richness of the epiphyte community studied. Our results demonstrate that the 21 richness and abundance of epiphytes were correlated with phorophyte size (as mensured by 22 the DBH, diameter at breast height), probably due to increased habitat area and the time 23 available for colonization. -

Breeding System and Pollination by Mimicry of the Orchid Tolumnia Guibertiana in Western Cubapsbi 322 163..173
Plant Species Biology (2011) 26, 163–173 doi: 10.1111/j.1442-1984.2011.00322.x Breeding system and pollination by mimicry of the orchid Tolumnia guibertiana in Western Cubapsbi_322 163..173 ÁNGEL VALE,* LUIS NAVARRO,* DANNY ROJAS* and JULIO C. ÁLVAREZ† *Department of Vegetal Biology, University of Vigo, Campus As Lagoas-Marcosende, Vigo, Spain and †Faculty of Biology, University of Havana, Vedado, Cuba Abstract The mimicry of malpighiaceous oil-flowers appears to be a recurrent pollination strategy among many orchids of the subtribe Oncidiinae. These two plant groups are mainly pollinated by oil-gathering bees, which also specialize in pollen collection by buzzing. In the present study, the floral ecology of the rewardless orchid Tolumnia guibertiana (Onci- diinae) was studied for the first time. The orchid was self-incompatible and completely dependent on oil-gathering female bees (Centris poecila) for fruit production. This bee species was also the pollinator of two other yellow-flowered plants in the area: the pollen and oil producing Stigmaphyllon diversifolium (Malpighiaceae) and the polliniferous and buzzing-pollinated Ouratea agrophylla (Ochnaceae). To evaluate whether this system is a case of mimetism, we observed pollinator visits to flowers of the three plant species and compared the floral morphometrics of these flowers. The behavior, preferences and move- ment patterns of Centris bees among these plants, as well as the morphological data, suggest that, as previously thought, flowers of T. guibertiana mimic the Malpighiaceae S. diversifolium. However, orchid pollination in one of the studied populations appears to depend also on the presence of O. agrophylla. Moreover, at the two studied populations, male and female pollination successes of T. -
