The diversity of wild orchids in the southern slope of Mount Merapi, Yogyakarta, Indonesia eight years after the 2010 eruption. Biodiversitas 21: 4457-4465. The ecosystem of the slopes of Mount Merapi is mountain tropical forest which is frequently affected by volcanic activities. The dynamics of the volcano affect the diversity and abundance of orchids in the ecosystem. Tritis is an area included in the Turgo Hill of the southern slope of Mount Merapi and is under the management of Mount Merapi National Park. The ecosystem in Tritis area classified as lower mountain forest and it has been affected by Mount Merapi eruption. This study aimed to do an inventory of orchid species in Tritis to know the diversity and abundance of orchids that exist in this area.

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.

The aim of this study was to investigate the diversity of orchids and their host trees (phorophytes) in a secondary forest of Coban Trisula (the Trisula waterfall) of Bromo Tengger Semeru National Park in East Java Province, Indonesia. Two line transects were established.E ach transect was 150 m long and composed of fifteen 10 x 10 m plots, resulting in the total number of 30 sampling plots at the study site. The following data were recorded in each plot: species name and individual numbers of epiphytic orchids, species name and individual numbers of the phorophytes and vertical distribution of the orchids on the phorophyte. There were 15 epiphytic orchid species found from 13 genera in the secondary forest of Coban Trisula. Appendicula angustifolia was the most abundant epiphytic orchid species (Relative abundance = 52. 4%), followed by Trichotosia annulata (29 . 9%). All recorded orchids grew on 21 individuals from nine phorophyte species. Castanopsis javanica (mean = 589.5 individuals/tree) and E ngelhardia spicata (mean = 425. 67 orchid individuals/tree ) were phorophytes hosting the largest number of individual orchids, respectively.

  • 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.

Of them, 50 species are epiphytic (including lithophytes) and 19 species are terrestrial. Information regarding habit and habitat, phenology, host species and elevational range of distribution of each species are provided in the checklist.

Shakuntala Manay Here is Nagesh’s story, the first recipient of TOSKAR Rolling Shield for the Best Orchid. His interest in growing plants started as a child of eight when he would pick up sprouting onions from Mom’s kitchen onion and plant them in the yard and watched them grow into green leeks. This got him into the hobby to grow vegetables. By this time he was 14. Later he turned to growing foliage plants like succulents, Anthuriums and Cacti. Thus he dared to enter into annual shows at Lalbagh and won many prizes. In “small homes garden” categories he won eight awards from Urban Art Commission such as “Best Maintained Building & Garden” “Pride of Bangalore” “Role of Honour” etc. Ex- commissioners of Bangalore City Corporation Late N. Laxman Rao and Late Mr. Parthsarathy would visit his house as Judges. He received these prestigious prizes amidst distinguished guests and dignitaries at Rajbhavan. Trophies gathered so fast that there was no place for them at home. Twenty years ago he got one orchid from Indo American Nursery. Thus he began collecting orchids from Kerala, North East India and Western Ghats. Now on his terrace of 800 sq ft he has 1500 orchids! Among these Dracula Orchid (Monkey face) which grows in cloud mountains of Mexico, Central America and Colombia is one of his special collections, and more than 15 varieties of Carnivorous Plants and many Tillandsias also add to his collection.
