Hoehnea 42(4): 663-686, 3 fig., 2015 http://dx.doi.org/10.1590/2236-8906-26/2015 Subtribo Oncidiinae Benth. (Orchidaceae Juss.) no Distrito Federal, Brasil1 Viviane Vaz de Queiroz2,4, Carolyn Elinore Barnes Proença2 e Luciano de Bem Bianchetti3 Recebido: 20.04.2015; aceito: 17.09.2015 ABSTRACT - (Subtribe Oncidiinae Benth. (Orchidaceae Juss.) in Distrito Federal, Brazil). Oncidiinae is the second largest subtribe of the orchids in the Americas. According to the Brazilian database Lista de Espécies da Flora do Brasil, the representativity of the subtribe in Distrito Federal is of 15 genera and 19 species. The objective of this study was to develop a taxonomic treatment of the subtribe for the Flora of Distrito Federal, Brazil. Field trips, consultations to the herbaria BHCB, CEN, HEPH, IBGE, and UB and morphological analysis of all the material were made. A new occurrence of species and genus, Trichopilia brasiliensis Cong., was registered to Distrito Federal After this study, the taxa list for Oncidiinae of Distrito Federal should be corrected to 15 genera and 18 species. Descriptions, identification keys, and illustrations for taxa were prepared. We concluded that some species of Oncidiinae occurring in Distrito Federal have wide distribution while others are locally rare and require intense effort of collection for registration. Keywords: Brasília, floristics, morphology, orchids, taxonomy RESUMO - (Subtribo Oncidiinae Benth. (Orchidaceae Juss.) no Distrito Federal, Brasil). Oncidiinae é a segunda maior subtribo de orquídeas das Américas. Segundo a Lista de Espécies da Flora do Brasil, a representatividade da subtribo no Distrito Federal é de 15 gêneros e 19 espécies. -

UV Reflectance but No Evidence for Colour Mimicry in a Putative Brood-Deceptive Orchid Corybas Cheesemanii
Current Zoology 60 (1): 104–113, 2014 UV reflectance but no evidence for colour mimicry in a putative brood-deceptive orchid Corybas cheesemanii M. M. KELLY, A. C. GASKETT* School of Biological Sciences, The University of Auckland, Private Bag 92019, Auckland 1142, New Zealand Abstract Rewardless orchids attract pollinators by food, sexual, and brood-site mimicry, but other forms of sensory deception may also operate. Helmet orchids (Corybas, Nematoceras and related genera) are often assumed to be brood-site deceivers that mimic the colours and scents of mushrooms to fool female fungus gnats (Mycetophilidae) into attempting oviposition and polli- nating flowers. We sampled spectral reflectances and volatile odours of an endemic terrestrial New Zealand orchid Corybas cheesemanii, and co-occurring wild mushrooms. The orchid is scentless to humans and SPME GC-MS analyses did not detect any odours, but more sensitive methods may be required. The orchids reflected strongly across all visible wavelengths (300700nm) with peaks in the UV (~320nm), yellow-green (500600 nm) and red regions (650700 nm), whereas mushrooms and surrounding leaf litter reflected predominantly red and no UV. Rather than mimicking mushrooms, these orchids may attract pollinators by exploiting insects’ strong sensory bias for UV. Modelling spectral reflectances into a categorical fly vision model and a generic tetrachromat vision model provided very different results, but neither suggest any mimicry of mushrooms. However, these models require further assessment and data on fly spectral sensitivity to red wavelengths is lacking – a problem given the predominance of red, fly-pollinated flowers worldwide [Current Zoology 60 (1): 104113, 2014]. Keywords Diptera, Colour space, Fly pollination, Orchidaceae, Spectral reflectance, Visual modelling Flowers typically attract pollinators by advertising in the Orchidaceae, in which approximately one-third of rewards such as food (Chittka and Thompson, 2001; species do not reward their pollinators (Jersáková et al., Raguso, 2004). -

A total of 281 individuals were used to construct regional descriptions of D. kingianum and 139 individuals were measured for 19 morphological characters, and similarities and differences among specimens summarised using multivariate statistical methods. Patterns of morphological variation within D. kingianum are consistent with a single variable species that expresses clinal variation, with short-growing plants in the south and taller plants in the northern part of the distribution. The nrITS gene tree suggests two subgroups within D. kingianum subsp. kingianum, one comprising northern, the other southern individuals, which may overlap in the vicinity of Dorrigo, New South Wales.

65 Possibly Lost Orchid Treasure of Bangladesh
J. biodivers. conserv. bioresour. manag. 3(1), 2017 POSSIBLY LOST ORCHID TREASURE OF BANGLADESH AND THEIR ENUMERATION WITH CONSERVATION STATUS Rashid, M. E., M. A. Rahman and M. K. Huda Department of Botany, University of Chittagong, Chittagong 4331, Bangladesh Abstract The study aimed at determining the status of occurrence of the orchid treasure of Bangladesh for providing data for Planning National Conservation Strategy and Development of Conservation Management. 54 orchid species are assessed to be presumably lost from the flora of Bangladesh due to environmental degradation and ecosystem depletion. The assessment of their status of occurrence was made based on long term field investigation, collection and identification of orchid taxa; examination and identification of herbarium specimens preserved at CAL, E, K, DACB, DUSH, BFRIH,BCSIRH, HCU; and survey of relevant upto date floristic literature. These species had been recorded from the present Bangladesh territory for more than 50 to 100 years ago, since then no further report of occurrence or collection from elsewhere in Bangladesh is available and could not be located to their recorded localities through field investigations. Of these, 29 species were epiphytic in nature and 25 terrestrial. More than 41% of these taxa are economically very important for their potential medicinal and ornamental values. Enumeration of these orchid taxa is provided with updated nomenclature, bangla name(s) and short annotation with data on habitats, phenology, potential values, recorded locality, global distribution conservation status and list of specimens available in different herbaria. Key words: Orchid species, lost treasure, Bangladesh, conservation status, assessment. INTRODUCTION The orchid species belonging to the family Orchidaceae are represented mostly in the tropical parts of the world by 880 genera and about 26567 species (Cai et al. -

Using the “Seidenfaden collection” in Copenhagen as an example, we address the common view that botanical garden collections of orchids are important for conservation. Seidenfaden collected live orchids all over Thailand from 1957 to 1983 and created a traditional collection for taxonomic research, characterized by high taxonomic diversity and low intraspecific variation. Following an extended period of partial neglect, we managed to set up a five-year project aimed at expanding the collection with a continued focus on taxonomic diversity, but widening the geographic scope to tropical Asia. -
Plastome Structure and Adaptive Evolution of Calanthe S.L. Species
Plastome structure and adaptive evolution of Calanthe s.l. species Yanqiong Chen, Hui Zhong, Yating Zhu, Yuanzhen Huang, Shasha Wu, Zhongjian Liu, Siren Lan and Junwen Zhai Key Laboratory of National Forestry and Grassland Administration for Orchid Conservation and Utilization at College of Landscape Architecture, Fujian Agriculture and Forestry University, Fuzhou, Fujian, China Fujian Ornamental Plant Germplasm Resources Innovation & Engineering Application Research Center, Fujian Agriculture and Forestry University, Fuzhou, Fujian, China ABSTRACT Calanthe s.l. is the most diverse group in the tribe Collabieae (Orchidaceae), which are pantropical in distribution. Illumina sequencing followed by de novo assembly was used in this study, and the plastid genetic information of Calanthe s.l. was used to investigate the adaptive evolution of this taxon. Herein, the complete plastome of five Calanthe s.l. species (Calanthe davidii, Styloglossum lyroglossa, Preptanthe rubens, Cephalantheropsis obcordata, and Phaius tankervilliae) were determined, and the two other published plastome sequences of Calanthe s.l. were added for comparative analyses to examine the evolutionary pattern of the plastome in the alliance. The seven plastomes ranged from 150,181 bp (C. delavayi) to 159,014 bp (C. davidii) in length and were all mapped as circular structures. Except for the three ndh genes (ndhC, ndhF, and ndhK ) lost in C. delavayi, the remaining six species contain identical gene orders and numbers (115 gene). Nucleotide diversity was detected across the plastomes, and we screened 14 mutational hotspot regions, including 12 non-coding regions and two gene regions. For the adaptive evolution investigation, three species showed positive selected genes compared with others, C. -
