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

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. -

Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa). -

This has resulted in the transfer of taxa previously considered to be species of Oncidium Sw. into Gomesa R. Br. and the re-circumscription of both genera. In this study, the structure of the floral elaiophore (oil gland) is described and compared for Gomesa echinata (Barb. Rodr.) M.W. Chase & N.H. Williams, G. ranifera (Lindl.) M.W. Chase & N.H. Williams, Oncidium amazonicum (Schltr.) M.W. Chase & N.H. Williams and O. oxyceras (Ko¨niger & J.G. Weinm.) M.W. Chase & N.H. Williams in order to determine whether phylogenetic revision is supported by differences in its anatomy. † Methods The floral elaiophore structure was examined and compared at three developmental stages (closed bud, first day of anthesis and final stage of anthesis) for all four species using light microscopy, fluorescence microscopy, scanning electron microscopy, transmission electron microscopy and histochemistry. -

The user has requested enhancement of the downloaded file. The Genus Systeloglossum ROBERT L. DRESSLER AND NORRIS H. WILLIAMS HE COMPLEX OF GENERA which make up the subtribe Oncidiinae are notable for their great diversity of flower structure. It is not surprising T that Schlechter grouped these genera into as many as ten different btribes. How can one imagine close relationships between Notylia and ~richoPilia, or Quekettia and Odontoglossum? In spite of their striking differences, we now group them all into the subtribe Oncidiinae, for two 'mportant reasons. First, crossing experiments, especially those of Mr. Moir, ~ave shown that the whole group is closely tied together by interfertility. We may not be able to cross Comparettia with Brassia, but we can cross both with Oncidium. The second reason for grouping them together is that even the morphological differences do not hold up very well on close inspection. Notylia may seem very different from Trichopilia, but Notylia and Macradenia are surely closely related, and Macradenia and Trichopilia subulata are perhaps more similar to each other than T . -

When virtual benching was first proposed I thought it might take members a little while to get on board with the idea. But no, there was terrific participation right from the start and a magical 6 page array of delicious, very professionally presented orchids, was created by Jenny. It included Cattleyas of all kinds and colours, Dendrobiums, Oncidiinae hybrids and rare species. It was just amazing. 14 different members contributed and if you count husbands and wives as separate it would be even more. The Fulchers provided a whole page of photos of orchids in flower from their collection, and even added a little info on each. -

Av. Miguel Estéfano, 3687, Água Funda, São Paulo, São Paulo, Brazil; e-mail: [email protected] 2Museu Paraense Emilio Goeldi, Coordenação de Botânica. Av. Perimetral, 1901, Montese, Belém, São Paulo, Brazil. Abstract Macradenia grandiflora a new species from southeastern Brazil is described and illustrated. It is related to M. lutescens, but differs by the number of lip calli, the size of sepals, petals and lip, the number of flowers per inflorescence, the cuspidate apex of sepals and petals, and the irregularly lacerate margin of the clinandrium. Key words: Macradenia, Oncidiinae, southeastern Brazil Introduction Macradenia Brown (1822: 612) is a small Neotropical genus of the subtribe Oncidiinae, which is closely related to eight genera of the “twig epiphyte clade” (Chase et al. 2009). Currently, the genus is composed by 12 species, ranging from Mexico and south Florida, throughout Central America, West Indies, to Bolivia, Brazil and Peru, growing in places with high humidity from sea level up to 300 m above sea level (Pupulin & Ossenbach 2002, Chase et al. 2009). In Brazil, Macradenia is represented by 10 species distributed in 13 states (Barros et al. 2015). The genus was described by Robert Brown in 1822, however it was never reviewed. -
