It has a single, sparsely hairy, long, thin leaf and one or two white flowers with greenish-white backs, on a thin stalk. DescriptionCaladenia nothofageti is a terrestrial, perennial, deciduous, herb with an underground tuber. It has a single, sparsely hairy, bright green leaf {{convert|40-180|mm|in|sigfig=1|abbr=on}} long and {{convert|1-3|mm|in|sigfig=1|abbr=on}} wide. One or sometimes two white flowers with a greenish-white back, {{convert|14-16|mm|in|sigfig=1|abbr=on}} across are borne on a thin, wiry stem {{convert|50-100|mm|in|sigfig=1|abbr=on}} tall. The sepals and petals are {{convert|80-95|mm|in|sigfig=1|abbr=on}} long and {{convert|2-3|mm|in|sigfig=1|abbr=on}} wide.The dorsal sepal is erect, to slightly curved forward, the lateral sepals and petals are held horizontally or slightly downwards. The labellum is {{convert|5-7|mm|in|sigfig=1|abbr=on}} long, about {{convert|5|mm|in|sigfig=1|abbr=on}} wide and white or (rarely) cream-coloured with faint red bars. The sides of the labellum turn upwards and partly embrace the column and there are four to six blunt teeth on the edges near the front, with the tip of the labellum curled under. There are two rows of pale yellow calli along the centre of the labellum. Flowering occurs from November to January but the flowers are self-pollinating and only open for a day or two.[1][2][3]Taxonomy and namingCaladenia nothofageti was first formally described in 1997 by David Jones, Brian Molloy and Mark Clements and the description was published in The Orchadian.[4]Distribution and habitatBeech caladenia occurs on both the North and South Island of New Zealand growing in Nothofagus forest in well-lit sites.[1][2] ConservationCaladenia nothofageti is listed as "not threatened" in New Zealand.[1][2]References1. ^1 2 {{cite web|title=Caladenia nothofageti|url=http://m.nzpcn.org.nz/flora_details.aspx?ID=1108|publisher=New Zealand Plant Conservation Network|accessdate=24 February 2017}} {{Taxonbar|from=Q15287592}}2. ^1 2 {{cite web|title=Caladenia nothofageti|url=http://www.nativeorchids.co.nz/Species/Caladenia_nothofageti.html|publisher=New Zealand Native Orchid Group|accessdate=24 February 2017}} 3. ^{{cite book|last1=Pridgeon|first1=Alec (ed.)|last2=Cribb|first2=Phillip J.|last3=Chase|first3=Mark W.|last4=Rasmussen|first4=Finn|title=Genera Orchidacearum.
