Research Priorities and Future Directions in Conservation of Wild Orchids in Sri Lanka: a Review
Nature Conservation Research. Заповедная наука 2020. 5(Suppl.1): 34–45 https://dx.doi.org/10.24189/ncr.2020.029 RESEARCH PRIORITIES AND FUTURE DIRECTIONS IN CONSERVATION OF WILD ORCHIDS IN SRI LANKA: A REVIEW J. Dananjaya Kottawa-Arachchi1,*, R. Samantha Gunasekara2 1Tea Research Institute of Sri Lanka, Sri Lanka 2Lanka Nature Conservationists, Sri Lanka *e-mail: [email protected], [email protected] Received: 24.03.2020. Revised: 22.05.2020. Accepted: 29.05.2020. Together with Western Ghats, Sri Lanka is a biodiversity hotspot amongst the 35 regions known worldwide. Considering the Sri Lankan orchids, 70.6% of the orchid species, including 84% of the endemics, are categorised as threatened. The distribution of the family Orchidaceae is mostly correlated with the distribution pattern of the main bioclimatic zones which is governed by the amount and intensity of rainfall and altitude. Habitat deterioration and degradation, clearing of vegetation, intentional forest fires and spread of invasive alien species are significant threats to native species. Illegally collection and exporting of indigenous species has been another alarming issue in the past decades. Protection of native species, increased public awareness, enforcement of legislation and introduction of new propagation techniques would certainly bring a beneficial effect to the native orchid flora. Conduct awareness programs, strengthen existing laws, and reviewing the legal framework related to the native orchid flora could be vital for future conservation. Apart from the identification of new species and their distribution, future research on understanding soil chemical and physical parameters of terrestrial habitats, plant association of terrestrial orchids, phenology patterns and interactions of pollinators, associations with mycorrhiza, effect of invasive alien species and impact of climate change are highlighted. -

Thirty-one morphological characters were considered; six vegetative and twenty-five floral, of which five were qualitative and twenty-six were quantitative characters. The data were subjected to Cluster Analysis (CA) and Principal Component Analysis (PCA). Cluster analysis has produced two prominent clusters, D. aphyllum, D. nutans and D. panduratum as cluster 1 and D. crumenatum and D. heterocarpum as cluster 2. Both D. nutans and D. panduratum are producing small sized floral parts, compared to D. aphyllum hence exhibits close similarities in floral morphology which resulted in forming a cluster of most closely related species with least dissimilarity values. With respect to many characteristics, two species incluster 2, D. crumenatum and D. heterocarpum, are found to be similar except for the leaf thickness. Furthermore, PCA also in agreement with the relationships derived from the cluster analysis. -
Epilist 1.0: a Global Checklist of Vascular Epiphytes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong. -

Rheedea Vol. 18(1) 1-28 2008 An Annotated Checklist of the Orchids of Sri Lanka 1 Samantha Suranjan Fernando and Paul Ormerod Post Graduate Institute of Science, University of Peradeniya, Peradeniya, Sri Lanka. E-mail: [email protected] 1P.O. Box 8210, Cairns 4870, Queensland, Australia. E-mail: [email protected] Abstract A general description of Sri Lanka and its bioclimatic zones are presented. The history of the Island’s orchid taxonomy is briefly reviewed. An updated checklist is presented for the country’s orchid flora using recent information. New species, new records and nomenclatural changes from previous lists are annotated with appropriate references. This work lists 188 species belonging to 78 genera with one endemic genus (Adrorhizon Hook. f.) and 55 endemic species. A new name, Bulbophyllum jayaweerae Fernando et Ormerod, is proposed for Cirrhopetalum roseum Jayaweera. Illegitimacy of the name Saccolabium virescens Gardner ex Lindl. is discussed and this species is described as a new taxon, Robiquetia virescens Ormerod et Fernando. Keywords: Sri Lanka, Orchids, Bulbophyllum jayaweerae, Robiquetia virescens, New name, New taxon Introduction Sri Lanka is a pear shaped island in the Indian Ocean lying in the southern tip of the Indian Peninsula (Fig. 1).

The main aim of the present research was to characterize selected species of genera Dendrobium and Bulbophyllum in Sri Lanka with respect to their ITS sequence data and to derive phylogenetic relationships. Modified CTAB protocol was followed for DNA extractions and ITS region was amplified using the primer sets of 17SE and 26SE and phylogenetic trees were constructed based on the available ITS sequences of the Asian species of Dendrobium and Bulbophyllum by MEGA7 software package. Genetic variation and relationships of six Sri Lankan orchid species; Dendrobium aphyllum, D. crumenatum, D. nutantiflorum endemic species of Bulbophyllum elliae, B. trimenii and Eria bicolor were determined using ITS sequencing. Findings of the analysis conclude, suitability of ITS sequencing as a molecular marker for deriving phylogenetic relationships of genera Dendrobium and Bulbophyllum with Eria as the out group. -
Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G
Taxonomy and Conservation Status of Pteridophyte Flora of Sri Lanka R.H.G. Ranil and D.K.N.G. Pushpakumara University of Peradeniya Introduction The recorded history of exploration of pteridophytes in Sri Lanka dates back to 1672-1675 when Poul Hermann had collected a few fern specimens which were first described by Linneus (1747) in Flora Zeylanica. The majority of Sri Lankan pteridophytes have been collected in the 19th century during the British period and some of them have been published as catalogues and checklists. However, only Beddome (1863-1883) and Sledge (1950-1954) had conducted systematic studies and contributed significantly to today’s knowledge on taxonomy and diversity of Sri Lankan pteridophytes (Beddome, 1883; Sledge, 1982). Thereafter, Manton (1953) and Manton and Sledge (1954) reported chromosome numbers and some taxonomic issues of selected Sri Lankan Pteridophytes. Recently, Shaffer-Fehre (2006) has edited the volume 15 of the revised handbook to the flora of Ceylon on pteridophyta (Fern and FernAllies). The local involvement of pteridological studies began with Abeywickrama (1956; 1964; 1978), Abeywickrama and Dassanayake (1956); and Abeywickrama and De Fonseka, (1975) with the preparations of checklists of pteridophytes and description of some fern families. Dassanayake (1964), Jayasekara (1996), Jayasekara et al., (1996), Dhanasekera (undated), Fenando (2002), Herat and Rathnayake (2004) and Ranil et al., (2004; 2005; 2006) have also contributed to the present knowledge on Pteridophytes in Sri Lanka. However, only recently, Ranil and co workers initiated a detailed study on biology, ecology and variation of tree ferns (Cyatheaceae) in Kanneliya and Sinharaja MAB reserves combining field and laboratory studies and also taxonomic studies on island-wide Sri Lankan fern flora. -

Of all the families of plants orchids are the largest. There are an estimated 750 to 1,000 genera and more than 25,000 species of orchids known today, with the number growing each year! The largest number of species is found in the Dendrobium (1,500 spp), Bulbophyllum (1,500 spp), and Pleurothalis (1,000 spp) genera. They are found on every continent in the world with the largest variety found in Asia. There are even species which use hot springs in Greenland to grow. Orchids can be epiphytic (growing high in the trees), terrestrial (growing in the ground), lithophytes (grow on rocks), and a few are saprophytic (living off decaying vegetation). The family is prized for its beautiful and diverse flowers. The only plant with an economic value to the common man is vanilla, which is a commonly enjoyed flavoring. The hybridizing of these flowers has become a major economic force worldwide for cut flowers and cultivation of plants by hobbyists. -

The Systematic Distribution of Vascular Epiphytes: an Update
Selbyana 9: 2-22 THE SYSTEMATIC DISTRIBUTION OF VASCULAR EPIPHYTES: AN UPDATE w. JOHN KREss Marie Selby Botanical Gardens, 811 South Palm Avenue, Sarasota, Florida 33577 ABSTRACT. The list of vascular plant families and genera containing epiphytic species published by Madison (1977) is updated here. Ten percent (23,456 species) of all vascular plant species are epiphytes. Seven percent (876) of the genera, 19 percent (84) of the families, 45 percent (44) of the orders and 75 percent (6) of the classes contain epiphytes. Twenty-three families contain over 50 epiphytic species each. The Orchidaceae is the largest family of epiphytes, containing 440 epiphytic genera and 13,951 epiphytic species. Forty-three genera of vascular plants each contain over 100 epiphytic species. In 1977 Madison published a list of the vas those plants that normally spend their entire life cular plant families and genera that contain epi cycle perched on another plant and receive all phytic species.
