Caladenia behrii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy, narrow lance-shaped leaf, 5–10 cm (2–4 in) long that develops during winter.

The lateral sepals and petals are 5–8 cm (2–3 in) long, creamy-white in colour with red glandular tips that produce an aroma described as "strong musky" or "subtle spicy".

Flowering occurs in August and September and is followed by an oblong-shaped capsule which releases hundreds of seeds in late October or November.

[2][3][4] Caladenia behrii was first formally described by Diederich Schlechtendal in 1847 and the description was published in Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde.
