ISSN: 0973-9467 © East Himalayan Society for Spermatophyte Taxonomy A checklist of orchids in Tinsukia District of Assam, India Khyanjeet Gogoi Daisa Bordoloi Nagar, Talap, Tinsukia- 786156, Assam, India E-mail: [email protected] Revised 04.05.2012; Accepted 05.06.2012 Abstract Tinsukia District has a vast stretch of forest cover with varied vegetation; those host many interesting species of orchids. This paper deals with the orchid flora of this district that consists of 95 species covering 48 genera, including terrestrial and epiphytic and concerned with morphological and ecological notes. Key words: Orchid Flora, Tinsukia, Distribution, Enumeration INTRODUCTION The Orchidaceae is one of the most highly specialized and larger families of flowering plants represented by more than 17000 species in nearly 1000 genera in the world and more and more new ones are being added every day (Chowdhery 1998). According to Kumar & Manilal (1994) 1141 species of Orchids in 166 genera are recorded from India, of which a major number of species are endemic. Out of 1141 species of Orchids reported so far from India about 800 species are from North-East India alone (Barua 2001). Assam the second largest state of India, is hosting many interesting Orchids like the other North-Eastern states. But, till date, no comprehensive record of Orchid flora of Assam is available. However according to Rao (1995) the actual enumeration of Orchids of Assam may be around 182 species covering 74 genera. Study area Tinsukia is an extremely important district of Assam in the north-eastern part of India with an area of about 3790 sq km. The district is located at 95022/ E to 95038/ E longitude and 27023/ N to 27028/ N latitude, at a height of 147.83 to 148.30 m AMSL (Map 1). The district is bounded at north by the mighty river Brahmaputra and the state of Arunachal Pradesh, on the west by Dibrugarh district and the on the east and south by Arunachal Pradesh. The area is very rich in terms of biodiversity and is very significant so far wildlife and forests are concerned. There are 35 reserve forests with a total area of 917.31 sq km, one National Park (Dibru- Saikhowa, 340 sq km) and one Wildlife Sanctuary (Borajan Padumoni 7.2 sq km), which covers about 33 % of the geographic area of the district (Mahanta 2002). The Tinsukia district is located in the sub-tropical region which therefore experiences high rainfall and high humidity. The annual rainfall ranges from 2300 mm to 3800 mm most of it is received during June – September with little rains in winters too. The average temperature is 360 C maximum and about 80 C minimum. The ambient high temperature is often checked by frequent showers and thunderstorms. Based on the floristic composition it can be broadly classified into two forest types. The first type is Hollong Nahar forests and this type corresponds to the Assam valley tropical wet 6 Orchids of Tinsukia District of Assam evergreen forest of Champion & Seth’s (1968) revised classification of forest types. The second type is termed as Miscellaneous forests, which is further subdivided in to Mixed deciduous forests and Mixed deciduous forest with evergreen patches. The climatic ambience of different types of vegetation in Tinsukia district suits well for the occurrence of numerous species of orchids. Recorded species of orchids are distributed in almost all zones of the forest according to their temperature and light requirement which varies from species to species, and some terrestrial orchids are found only in grasslands and riverbanks. The present study attempts to provide the information on the orchid flora of Tinsukia district based on recent collections. MATERIALS AND METHODS The present study is the result of several field trips covering all the seasons during 1996 to 2011 in different locations of Tinsukia district. The collected specimens were dissected and examined in laboratory during flowering period. Herbarium specimens were prepared by standard methods (Jain & Rao 1977). Specimens were identified with the help of literature and matched at the herbarium of department of Botany Guwahati University (GUBH) and at ASSAM. Herbarium specimens have been deposited at the GUBH. In the enumeration a generic name is accompa- nied by citation of the number of species in India and in this area and a species with author citation is supported with its flowering and habitat. RESULTS All the species of orchids recorded from the Tinsukia district of Assam during the present taxonomic survey is enumerated below with names of genera alphabetically and, again, species under each genus alphabetically. In the enumeration while a generic name is provided with the author citation only, a species binomial is followed by author citation, protologue reference, flowering period and habitat.

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.

  • Distribution of Vascular Epiphytes Along a Tropical Elevational Gradient: Disentangling Abiotic and Biotic Determinants
    www.nature.com/scientificreports OPEN Distribution of vascular epiphytes along a tropical elevational gradient: disentangling abiotic and Received: 23 June 2015 Accepted: 16 December 2015 biotic determinants Published: 22 January 2016 Yi Ding1, Guangfu Liu2, Runguo Zang1, Jian Zhang3,4, Xinghui Lu1 & Jihong Huang1 Epiphytic vascular plants are common species in humid tropical forests. Epiphytes are influenced by abiotic and biotic variables, but little is known about the relative importance of direct and indirect effects on epiphyte distribution. We surveyed 70 transects (10 m × 50 m) along an elevation gradient (180 m–1521 m) and sampled all vascular epiphytes and trees in a typical tropical forest on Hainan Island, south China. The direct and indirect effects of abiotic factors (climatic and edaphic) and tree community characteristics on epiphytes species diversity were examined. The abundance and richness of vascular epiphytes generally showed a unimodal curve with elevation and reached maximum value at ca. 1300 m. The species composition in transects from high elevation (above 1200 m) showed a more similar assemblage. Climate explained the most variation in epiphytes species diversity followed by tree community characteristics and soil features. Overall, climate (relative humidity) and tree community characteristics (tree size represented by basal area) had the strongest direct effects on epiphyte diversity while soil variables (soil water content and available phosphorus) mainly had indirect effects. Our study suggests that air humidity is the most important abiotic while stand basal area is the most important biotic determinants of epiphyte diversity along the tropical elevational gradient. Understanding the mechanisms of species distributions at different spatial scales remains a central question of community ecology and biogeography1.
