A recently recognised species 120–300 mm high with a hairy leaf 40–120 mm long by 4–6 mm wide and up to two cream or creamy-yellow flowers 70–130 mm across.

It is distinguished from the related Rock Spider Orchid (Caladenia petrensis) by its generally narrower leaf, usually single flowered inflorescence, larger flowers, narrower labellum and shorter column. It has a predominantly more westerly and north-westerly distribution than C. petrensis, overlapping only in the Mullewa area where they occur as separate populations and do not appear to intergrade.
