Caladenia atroclavia occurs on granite pavements and shallow gravely soils of granitic origin. It grows in open woodlands, but has also been recorded on swampy flats. (Sparshott 2007; Herbrecs 2008)


Caladenia atroclavia is a terrestrial orchid growing to 35cm tall. The flowers are produced singly on a wiry stalk, which is covered with coarse hairs up to 2.5mm long. The flower consists of four widely spreading petal-like leaves, with a fifth petal being held upright above the flower. The leaves are narrow lance-shaped, 8-12cm long by 5-10mm wide and are covered in hairs. The leaves are pale greenish-cream and may be irregularly blotched with red, pink or brown, and have distinct brown to black tips. The flower consists of a small cream 'hood' and a dark brown and cream 'tongue', with short dark appendages, which protrude from the throat of the flower. The flower has a fragrance resembling an overheated electrical motor. (Clements 1989; Sparshott 2007; DEWHA 2008)
