It has short stems, cylindrical green roots pressed against the substrate on which it is growing and between two and five small, tube-shaped, yellowish green flowers opening one at a time. It occurs on Norfolk Island but has also been reported from the North Island of New Zealand. DescriptionTaeniophyllum norfolkianum is a leafless, epiphytic herb with stems about {{convert|1|mm|in|sigfig=2}} long, and green, photosynthetic roots {{convert|15-30|mm|in|sigfig=2}} long, {{convert|1-2|mm|in|sigfig=2}} wide and circular in cross-section. There are between two and five yellowish green, resupinate, tube-shaped flowers about {{convert|2|mm|in|sigfig=2}} long and {{convert|1.5|mm|in|sigfig=2}} wide borne on a thread-like flowering stem {{convert|15-25|mm|in|sigfig=2}} long. The flowers open one at a time. The sepals and petals are fleshy with only their tips spreading, about {{convert|1.5|mm|in|sigfig=2}} long and {{convert|0.5|mm|in|sigfig=2}} wide. The labellum is boat-shaped, about {{convert|1.5|mm|in|sigfig=2}} long with a pointed appendage and a spur about {{convert|1.5|mm|in|sigfig=2}} long. Flowering occurs from August to September.[2][3]Taxonomy and namingTaeniophyllum norfolkianum was first formally described in 2006 by David Jones, Bruce Gray and Mark Clements and the description was published in The Orchadian from a specimen collected on Mount Bates.[1][4] The specific epithet (norfolkianum) refers to Norfolk Island. The ending -ianum is derived from the Latin suffix -anus meaning "pertaining to" or "belonging to".[5]Distribution and habitatThe Norfolk Island ribbonroot grows on the leafy branches of Norfolk Island pine (Araucaria heterophylla) but it has also been seen growing on gorse (Ulex europaeus) on the North Island of New Zealand.[2][3] {{Taxonbar|from=Q15464435}}References1. ^1 {{WCSP |348625 |Taeniophyllum norfolkianum}} 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=454}} 3. ^1 {{cite web |last1=de Lange |first1=Peter J. |title=Taeniophyllum norfolkianum |url=http://www.nzpcn.org.nz/flora_details.aspx?ID=6662 |publisher=New Zealand Plant Conservation Network |accessdate=7 January 2019}} 4. ^{{cite web|title=Taeniophyllum norfolkianum|url= https://id.biodiversity.org.au/instance/apni/609230|publisher=APNI|accessdate=7 January 2019}} 5. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=94}} 5 : Taeniophyllum|Endemic orchids of Australia|Flora of Norfolk Island|Orchids of New Zealand|Plants described in 2006 |
