It has between four and six leaves in a fan-like arrangement on each shoot and a large number of whitish to yellowish flowers arranged in whorls of between six and eight around the flowering stem. It is endemic to Queensland. DescriptionOberonia flavescens is an epiphytic or lithophytic herb that forms large clumps. Each shoot has between four and six fleshy, sword-shaped, green to reddish leaves {{convert|80-150|mm|in|sigfig=2|abbr=on}} long and {{convert|15-20|mm|in|sigfig=2|abbr=on}} wide with their bases overlapping. A large number of whitish or yellowish, non-resupinate flowers about {{convert|2.3|mm|in|sigfig=2|abbr=on}} long and {{convert|1.5|mm|in|sigfig=2|abbr=on}} wide are arranged in whorls of between six and eight on an arching flowering stem {{convert|100-200|mm|in|sigfig=2|abbr=on}} long. The sepals and petals are egg-shaped, about {{convert|1.2|mm|in|sigfig=2|abbr=on}} long and turned back towards the ovary. The labellum is about {{convert|1.5|mm|in|sigfig=2|abbr=on}} long with three fringed lobes. Flowering occurs between February and July.[2][3][4]Taxonomy and namingOberonia flavescens was first formally described in 2006 by David Jones and Mark Clements who published the description in Australian Orchid Research. The type specimen was grown in the Australian National Botanic Gardens from a plant collected in the McIlwraith Range.[5] The specific epithet (flavescens) is derived from the Latin word flavus meaning "golden-yellow" or "yellow"[6]{{rp|872}} with the suffix -escens meaning "beginning of" or "becoming".[6]{{rp|308}} Distribution and habitatThe northern green fairy orchid usually grows on trees and rocks in rainforest, sometimes in other humid, sheltered places such as mangroves. It is found between the Iron and Clarke Ranges in Queensland.[2][3][4] References1. ^{{WCSP |136315 |Oberonia flavescens}} {{Taxonbar|from=Q15475150}}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 =470}} 3. ^1 {{cite web |title=Oberonia flavescens |url=http://keys.trin.org.au:8080/key-server/data/08090a09-0d0e-410b-860c-020705070e0e/media/Html/Oberonia_flavescens.htm |publisher=Trin keys: Australian Tropical Rainforest Orchids |accessdate=16 January 2019}} 4. ^1 {{cite journal |last1=Jones |first1=David L. |last2=Clements |first2=Mark A. |title=Fourteen new taxa of Orchidaceae from Northern and Eastern Australia and two new combinations from new Guinea |journal=Australian Orchid Research |date=2006 |volume=5 |issue=1 |pages=10–11}} 5. ^{{cite web|title=Oberonia flavescens|url= https://id.biodiversity.org.au/instance/apni/616218|publisher=APNI|accessdate=16 January 2019}} 6. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 4 : Oberonia|Endemic orchids of Australia|Plants described in 2006|Orchids of Queensland |
