Each pseudobulb has a single pleated, leathery leaf and up to sixty white, cream-coloured or greenish, cup-shaped flowers in two ranks along a wiry flowering stem. There is a large, papery bract at the base of each flower. This species is native to areas from tropical and subtropical Asia to the southwest Pacific. DescriptionPholidota imbricata is an epiphytic or lithophytic, clump forming herb with crowded pseudobulbs {{convert|80-120|mm|in|sigfig=2|abbr=on}} long and {{convert|30-50|mm|in|sigfig=2|abbr=on}} wide. Each pseudobulb has a single pleated, leathery, dark green, oblong to lance-shaped leaf {{convert|200-400|mm|in|sigfig=2|abbr=on}} long and {{convert|60-80|mm|in|sigfig=2|abbr=on}} wide on a stalk about {{convert|50|mm|in|sigfig=2|abbr=on}} long. Between twenty and sixty cup-shaped, white, cream-coloured or greenish resupinate flowers {{convert|6-8|mm|in|sigfig=2|abbr=on}} long and {{convert|5-7|mm|in|sigfig=2|abbr=on}} wide are arranged in two rows along a wiry flowering stem {{convert|150-400|mm|in|sigfig=2|abbr=on}} long. There is a large, concave pinkish bract at the base of each flower. The dorsal sepal is {{convert|4-5|mm|in|sigfig=2|abbr=on}} long and {{convert|3-4|mm|in|sigfig=2|abbr=on}} wide, the lateral sepals {{convert|6-7|mm|in|sigfig=2|abbr=on}} long and about {{convert|3|mm|in|sigfig=2|abbr=on}} wide. The petals are {{convert|3-4|mm|in|sigfig=2|abbr=on}} long and about {{convert|1.5|mm|in|sigfig=2|abbr=on}} wide. The labellum is about {{convert|4|mm|in|sigfig=2|abbr=on}} long and {{convert|5|mm|in|sigfig=2|abbr=on}} wide and concave with three lobes. The side lobes are erect and the midlobe is divided again into three lobes. Flowering occurs between March and May.[2][3][4][5]Taxonomy and namingPholidota imbricata was first formally described in 1825 by William Jackson Hooker who published the description in Exotic Flora.[6][7] The specific epithet (imbricata) is a Latin word meaning "overlapping like roofing-tiles and shingles".[8]Distribution and habitatThe common rattlesnake orchid usually grows on trees and rocks in rainforest, sometimes in other humid, sheltered places. It occurs in China, the Indian Subcontinent, Cambodia, Laos, Myanmar, the Nicobar Islands, Thailand, Vietnam, Borneo, Java, the Lesser Sunda Islands, Peninsular Malaysia, the Maluku Islands, the Philippines, Sulawesi, Sumatra, the Bismarck Archipelago, New Guinea, the Solomon Islands, Queensland (Australia), Fiji, New Caledonia, the Santa Cruz Islands and Vanuatu.[1] In Queensland it is found on some Torres Strait Islands and on the Cape York Peninsula as far south as Townsville.[2][4] References1. ^1 2 {{WCSP |152772 |Pholidota imbricata}} {{Taxonbar|from=Q9291510}}2. ^1 2 {{cite book|last1=Jones|first1=David L.|title=A complete guide to native orchids of Australia including the island territories|date=2006|publisher=New Holland|location=Frenchs Forest, N.S.W.|isbn=1877069124|page =472}} 3. ^1 {{cite web |title=Necklace orchid |url=https://www.flowersofindia.net/catalog/slides/Necklace%20Orchid.html |publisher=Flowers of India |accessdate=16 January 2019}} 4. ^1 {{cite web |title=Pholidota imbricata |url=http://keys.trin.org.au:8080/key-server/data/08090a09-0d0e-410b-860c-020705070e0e/media/Html/Pholidota_imbricata.htm|publisher=Trin keys: Australian Tropical Rainforest Orchids |accessdate=17 January 2019}} 5. ^{{cite web |title=Pholidota imbricata |url=http://www.orchidsnewguinea.com/orchid-information/species/speciescode/683 |publisher=Orchids of New Guinea |accessdate=17 January 2019}} 6. ^{{cite web|title=Pholidota imbricata|url= https://id.biodiversity.org.au/instance/apni/502508|publisher=APNI|accessdate=17 January 2019}} 7. ^{{cite book |last1=Hooker |first1=William Jackson |title=Exotic Botany (Volume 2) |date=1825 |publisher=William Blackwood |location=Edinburgh |pages=138–139 |url=https://www.biodiversitylibrary.org/item/108948#page/177/mode/1up |accessdate=17 January 2019}} 8. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=434}} 9 : Pholidota|Orchids of Australia|Plants described in 1825|Orchids of China|Orchids of India|Orchids of Indonesia|Orchids of New Guinea|Orchids of New Caledonia|Orchids of Thailand |
