One or two greenish flowers with red stripes are borne on a spike {{convert|50-150|mm|in|sigfig=1|abbr=on}} tall. The sepals have thick, brown, club-like glandular tips {{convert|3-6|mm|in|sigfig=1|abbr=on}} long. The dorsal sepal curves forward and is {{convert|25-35|mm|in|sigfig=2|abbr=on}} long and about {{convert|2|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are {{convert|25-35|mm|in|sigfig=2|abbr=on}} long, about {{convert|3|mm|in|sigfig=1|abbr=on}} wide and are parallel to or sometimes cross over each other. The petals are {{convert|20-26|mm|in|sigfig=1|abbr=on}} long, {{convert|1-2|mm|in|sigfig=1|abbr=on}} wide and curve downwards.

The description was published in Indigenous Flora and Fauna Association Miscellaneous Paper 1.[4] The specific epithet (parva) is a Latin word meaning "little".[5]Distribution and habitatThe small spider orchid occurs in scattered locations across southern Victoria and the far south-eastern corner of South Australia where it grows woodland and coastal scrub.[1] ConservationCaladenia parva is not listed under the Victorian Flora and Fauna Guarantee Act 1988.[1]References1. ^1 2 {{cite web|last1=Jeanes|first1=Jeffrey|title=Caladenia parva|url=https://vicflora.rbg.vic.gov.au/flora/taxon/079e6097-322b-43ba-b9b0-92a34eed4ab9|publisher=Royal Botanic Gardens Victoria: Vicflora|accessdate=1 March 2017}} {{Taxonbar|from=Q9673830}}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 =92}} 3. ^{{cite web|title=Caladenia parva|url=http://fe.yarraranges.vic.gov.au/Residents/Trees_Vegetation/Yarra_Ranges_Plant_Directory/Yarra_Ranges_Local_Plant_Directory/Lower_Storey/Orchids/Caladenia_parva|publisher=Yarra Ranges Shire Council|accessdate=1 March 2017}} 4. ^1 2 {{cite web|title=Caladenia parva|url= https://id.biodiversity.org.au/instance/apni/553206|publisher=APNI|accessdate=1 March 2017}} 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=489}} 5 : Caladenia|Plants described in 1991|Endemic orchids of Australia|Orchids of South Australia|Orchids of Victoria (Australia) |
