It is a ground orchid with a single leaf and one or two greenish-cream flowers with pink stripes and which has a sharp odour resembling burnt plastic. DescriptionCaladenia osmera is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf, {{convert|60-120|mm|in|sigfig=1|abbr=on}} long and {{convert|5-10|mm|in|sigfig=1|abbr=on}} wide. One or two greenish-cream to cream-coloured flowers with pink stripes and blotches are borne on a spike {{convert|150-300|mm|in|sigfig=1|abbr=on}} tall. The flowers have a sharp odour resembling the smell of burnt plastic. The sepals and petals have narrow, dark red, club-like glandular tips {{convert|5-12|mm|in|sigfig=1|abbr=on}} long. The sepals and petals are {{convert|20-45|mm|in|sigfig=1|abbr=on}} long and {{convert|2-4|mm|in|sigfig=1|abbr=on}} wide with the petals shorter than the sepals. The sepals and petals spread widely and horizontally or curve downwards. The labellum is greenish-cream with a dark red tip and is {{convert|11-13|mm|in|sigfig=1|abbr=on}} long and {{convert|7-9|mm|in|sigfig=2|abbr=on}} wide. The sides of the labellum curve upwards and have linear teeth up to {{convert|25|mm|in|sigfig=1|abbr=on}} long, decreasing in size towards the tip. There are four or six rows of calli about {{convert|1|mm|in|sigfig=1|abbr=on}} long near the base of the labellum and tapering towards the tip. Flowering occurs in September and October.[1]Taxonomy and namingThis orchid was first formally described in 2006 by David Jones and given the name Arachnorchis osmera. The description was published in Australian Orchid Research.[2] In 2007 Gary Backhouse changed the name to Caladenia osmera.[3] The specific epithet (osmera) is derived from the Ancient Greek words osme meaning "smell" or "odour"[4] referring to the strong floral scent of this species.[5] Distribution and habitatCaladenia osmera is only known from areas east of Bruthen where it grows in tall montane forest.[1] It probably also occurs on the Southern Tablelands of New South Wales.[6]ConservationCaladenia osmera is listed as "vulnerable" under the Victorian Flora and Fauna Guarantee Act 1988.[1]References1. ^1 2 {{cite web|last1=Jeanes|first1=Jeffrey|title=Caladenia osmera|url=https://vicflora.rbg.vic.gov.au/flora/taxon/1213182e-626b-438f-b625-ce7a29fd6bae|publisher=Royal Botanic Gardens Victoria: Vicflora|accessdate=27 February 2017}} {{Taxonbar|from=Q15287625}}2. ^{{cite web|title=Arachnorchis osmera|url= https://id.biodiversity.org.au/instance/apni/616252|publisher=APNI|accessdate=27 February 2017}} 3. ^1 2 {{cite web|title=Caladenia osmera|url= https://id.biodiversity.org.au/instance/apni/616394|publisher=APNI|accessdate=27 February 2017}} 4. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=579}} 5. ^{{cite journal|last1=Jones|first1=David L.|title=New taxa of Australian Orchidaceae|journal=Australian Orchid Research|date=2006|volume=5}} 6. ^{{cite web|title=Caladenia osmera|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Caladenia~osmera|publisher=Royal Botanic Gardens Sydney: plantnet|accessdate=27 February 2017}} 5 : Caladenia|Plants described in 2006|Endemic orchids of Australia|Orchids of Victoria (Australia)|Taxa named by David L.
