The flowers are greenish-yellow, red and cream-coloured, shaped like a reclining spider and the sepals and petals have thin, thread-like tips.

The dorsal sepal and petals are close together and parallel, curved down behind the column near their bases, then upswept at the back of the flower.

[2][3][4] Caladenia multiclavia was first described in 1871 by Heinrich Reichenbach and the description was published in Beitrage zur Systematischen Pflanzenkunde.

[3] The lazy spider orchid occurs in a band between Wongan Hills and Ravensthorpe in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions where it grows in she-oak thickets and open woodland.

[2][3][4][7] Caladenia multiclavia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
