It is a common orchid within its natural range and has a single, hairy leaf and up to three pale yellow and red flowers which have short but thick, fleshy glandular tips.

There are a few short, pointed greenish teeth on the side of the labellum and four or more rows of maroon calli up to 2 mm (0.08 in) long along its centre line.

[1] The specific epithet (ensata) is derived from the Latin word ensis meaning "sword"[5] referring to the sword-like tips of the petals and sepals.

[3] Stumpy spider orchid is found between Albany and Augusta in the Jarrah Forest and Warren biogeographic regions where it usually grows in sandy soil in woodland.

[2][3][6] Caladenia ensata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
