}} Tainia trinervis, commonly known as the ribbon orchid,[2] is an evergreen, terrestrial plant with crowded pseudobulbs, each with a single smooth, shiny leaf and up to fourteen greenish to yellowish flowers with red or purplish stripes in the middle. It is found in tropical Southeast Asia, New Guinea and northern Australia. DescriptionTainia trinervis is an evergreen, terrestrial herb that has thin, crowded, dark green pseudobulbs. Each pseudobulb is {{convert|40-70|mm|in|sigfig=1|abbr=on}} long and {{convert|7-10|mm|in|sigfig=1|abbr=on}} wide and has a single smooth, shiny, dark green leaf {{convert|100-160|mm|in|sigfig=1|abbr=on}} long and {{convert|40-60|mm|in|sigfig=2|abbr=on}} wide on a stalk {{convert|30-50|mm|in|sigfig=1|abbr=on}} long. Between three and fourteen greenish white to yellowish resupinate flowers {{convert|13-18|mm|in|sigfig=1|abbr=on}} long and {{convert|20-25|mm|in|sigfig=1|abbr=on}} wide are well-spaced along a thin flowering stem {{convert|200-300|mm|in|sigfig=1|abbr=on}} tall. The sepals are {{convert|9-12|mm|in|sigfig=1|abbr=on}} long and {{convert|3-4|mm|in|sigfig=2|abbr=on}} wide with their tips curved back. The petals are a similar size to the sepals but project forwards. The labellum is {{convert|7-8|mm|in|sigfig=2|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide and has three lobes. The middle lobe has three purple ridges and a curved tip. The side lobes curve upwards. Flowering occurs from September to November.[2][3][4]Taxonomy and namingThe ribbon orchid was first formally described in 1856 by Carl Ludwig Blume who gave it the name Mitopetalum trinerve and published the description in Museum Botanicum Lugduno-Batavum sive stirpium Exoticarum, Novarum vel Minus Cognitarum ex Vivis aut Siccis Brevis Expositio et Descriptio.[5][6] In 1857, Heinrich Gustav Reichenbach changed the name to Tainia trinervis.[7] The specific epithet (trinervis) is derived from the Latin prefix tri- meaning three [8]{{rp|798}} and nervis meaning "vein".[8]{{rp|555}} Distribution and habitatTainia trinervis grows in rainforest close to streams in tropical far north Queensland, New Guinea and the Maluku Islands.[2][3][4]Footnotes1. ^1 {{WCSP | 201350 | Tainia trinervis }} {{Taxonbar|from=Q15465948}}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 =364}} 3. ^1 {{cite web |title=Tainia trinervis |url=http://keys.trin.org.au/key-server/data/08090a09-0d0e-410b-860c-020705070e0e/media/Html/Tainia_trinervis.htm|publisher=Trin keys |accessdate=4 November 2018}} 4. ^1 {{cite web |title=Taenia trinervis|url=http://www.orchidsnewguinea.com/orchid-information/species/speciescode/1035 |publisher=Orchids of New Guinea |accessdate=4 November 2018}} 5. ^{{cite web|title=Mitopetalum trinerve|url= https://id.biodiversity.org.au/instance/apni/552631|publisher=APNI|accessdate=4 November 2018}} 6. ^{{cite book |last1=Blume |first1=Carl Ludwig |title=Museum Botanicum Lugduno-Batavum sive stirpium Exoticarum, Novarum vel Minus Cognitarum ex Vivis aut Siccis Brevis Expositio et Descriptio|date=1856 |location=Leiden |page=185 |url=https://www.biodiversitylibrary.org/item/6964#page/186/mode/1up|accessdate=4 November 2018}} 7. ^{{cite web|title=Tainia trinervis|url= https://id.biodiversity.org.au/instance/apni/552622|publisher=APNI|accessdate=4 November 2018}} 8. ^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 : Tainia|Plants described in 1856|Orchids of New Guinea|Orchids of Queensland |
