Abstract: Orchids (Family Orchidaceae) are one of the components of biodiversity in ecosystems such as the epiphytic orchids of West Kalimantan which are endangered due to forest destruction. This research aims to found out the types of epiphytic orchids in the forest area of Bukit Luncit, Anjongan Sub-district. The research was carried out from May to July 2015 using the cruise method. Research finding showed that there were 9 genera of orchids divided into 12 species of epiphytic orchids i.e. Aerides odorata, Bulbophyllum lepidum, Bulbophyllum vaginatum, Cymbidium finlaysonianum, Dendrobium crumenatum, Dendrobium oblongum, Dendrobium smithianum, Luisia curtisii, Micropera fuscolutea, Pomatocalpa latifolia, Thrixspermum centipeda and Trichoglottis bipenicillata.

Abstract: The Andaman and Nicobar Islands are the largest archipelago system in the Bay of Bengal, consisting of 572 islands and islets. Being situated between two major biodiversity hotspots, namely the Indo-Burma and Sundaland Biodiversity Hotspots, endows it with an unmatched distribution of plants with representatives of the Indian, Myanmar, Malaysian and Indonesian floras (Balakrishnan & Ellis 1996). Nearly 2100 species of angiosperms have been reported from the islands, of which about 11% are strictly endemic (Balakrishnan & Ellis 1996). As these islands are situated in the Equatorial belt and are exposed to marine impacts having a warm and humid tropical climate, the entire area is suitable for growth of orchids. The Andaman and Nicobar Islands harbour about 158 species of orchids, of which 23 species are endemic (Karthigeyan et al. 2014, Singh et al. 2019).

Abstract: Sulawesi is the fourth largest island in Indonesia. Sulawesi is also a very unique island, possessing a very high biodiversity due to the location on the Wallacea area, and constituting mixing plants from Asia and Australia. An inventory and exploration of orchid in Polewali Mandar Regency was conducted from 25 May to 13 June 2014 to determine and assess the orchid diversity in the area. Orchid specimens were recorded and collected using a purposive random sampling method. A total of 60 accession numbers were collected in the study area. These collections represent 22 genera and 51 species, consists of 41 epiphyte orchids species and 10 terrestrial orchids species. Some species are wide distribute in Indonesia, few of them are only found in eastern part of Indonesia such as Wallacea region, and are even endemic to Sulawesi. Luisia celebica Schltr. and Micropera sterrophylla (Schltr.) Garay are noted as endemic orchid to Sulawesi. While Dendrobium bicaudatum Reinw. ex Lindl., Habenaria beccarii Schltr., Malaxis trigonopetala (J.J.Sm.) S.Thomas, Schuit. & de Vogel and Pinalia quinquangularis (J.J.Sm.) Ormerod are endemic to the Wallacea region mainly in Sulawesi and Moluccas. Among those orchids found in the study, Dendrobium clavator Ridl., Pinalia quinquangularis (J.J.Sm.) Ormerod, and Pinalia xanthocheila (Ridl.) W.Suarez & Cootes are noted as new records in Sulawesi. Many new records of orchids are still to be expected from Sulawesi.
