It is a ground orchid with a single leaf and one or two cream-coloured flowers with thin dark red to blackish tips on the petals and sepals. It is only known from Alligator Gorge in the Mount Remarkable National Park. DescriptionCaladenia flindersica is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, dull green, narrow lance-shaped leaf, {{convert|80-220|mm|in|sigfig=1|abbr=on}} long and {{convert|6-14|mm|in|sigfig=1|abbr=on}} wide with red or purple blotches near its base. The leaf and the flowering stem are densely covered with erect transparent hairs up to {{convert|3|mm|in|sigfig=1|abbr=on}} long. One or two cream coloured flowers {{convert|50-100|mm|in|sigfig=1|abbr=on}} wide are borne on a flowering stem {{convert|150-350|mm|in|sigfig=1|abbr=on}} tall. The flowers fade to white as they age and the petals and sepals have thin, dark red to blackish, glandular tips. The dorsal sepal is {{convert|40-80|mm|in|sigfig=1|abbr=on}} long, {{convert|3-4|mm|in|sigfig=1|abbr=on}} wide, oblong near the base then tapering to a glandular tip {{convert|30-55|mm|in|sigfig=1|abbr=on}} long and about {{convert|1|mm|in|sigfig=1|abbr=on}} wide. The lateral sepals are lance-shaped near their bases, {{convert|40-80|mm|in|sigfig=1|abbr=on}} long, {{convert|4-6|mm|in|sigfig=2|abbr=on}} wide and taper to narrow glandular tips similar to that on the dorsal sepal. The petals are {{convert|30-55|mm|in|sigfig=1|abbr=on}} long, {{convert|3-4|mm|in|sigfig=1|abbr=on}} wide, lance-shaped near the base then end in a glandular tip but shorter than those on the sepals. The labellum is lance-shaped to egg-shaped, {{convert|13-18|mm|in|sigfig=1|abbr=on}} long, {{convert|7-11|mm|in|sigfig=1|abbr=on}} wide and has five to eight pairs of linear teeth {{convert|1-2|mm|in|sigfig=1|abbr=on}} long on the edges. The tip of the labellum curls downward and there are four or six rows of purplish, stalked calli along the mid-line of the labellum. Flowering occurs in late August and September.[2]Taxonomy and namingCaladenia flindersica was first formally described in 2006 by David Jones, who gave it the name Arachnorchis flindersica and published the description in Australian Orchid Research from a specimen collected in Alligator Gorge.[3] In 2008, Robert Bates changed the name to Caladenia flindersica.[4][5] The specific epithet (flindersica) is a reference to the Flinders Ranges where this species occurs.[2]Distribution and habitatThis spider orchid is only known from in and near Alligator Gorge where it grows among shrubs in Eucalypt forest.[2] References1. ^{{WCSP | 372473 | Caladenia flindersica}} {{Taxonbar|from=Q15287551}}2. ^1 2 {{cite journal|last1=Jones|first1=David L.|title=New taxa of Australian Orchidaceae|journal=Australian Orchid Research|date=2006|volume=5|pages=60–61}} 3. ^{{cite web|title=Arachnorchis ensigera|url= https://id.biodiversity.org.au/instance/apni/616257|publisher=APNI|accessdate=8 February 2018}} 4. ^1 {{cite web|title=Caladenia flindersica|url= https://id.biodiversity.org.au/instance/apni/641207|publisher=APNI|accessdate=8 February 2018}} 5. ^{{cite journal|last1=Bates|first1=Robert John|title=New combinations in Pterostylis and Caladenia and other name changes in the Orchidaceae of South Australia|journal=Journal of the Adelaide Botanic Garden|date=2008|volume=22|page=102|url=https://data.environment.sa.gov.au/Content/Publications/JABG22P101_Barker.pdf|accessdate=3 April 2017}} 5 : Caladenia|Endemic orchids of Australia|Orchids of South Australia|Plants described in 2006|Taxa named by David L.
