It has a single smooth leaf and a single greenish yellow and red flower with a flattened labellum, the calli only near its tip.Caleana disjuncta has a single smooth, dull green or dull red leaf, 10–20 mm (0.4–0.8 in) long and 3–10 mm (0.1–0.4 in) wide. Usually only one greenish yellow and red flower, 12–18 mm (0.5–0.7 in) long and 8–12 mm (0.3–0.5 in) wide is borne on a thin, wiry stalk 50–130 mm (2–5 in) high. The dorsal sepal, lateral sepals and petals are 7–10 mm (0.3–0.4 in) long, 1–2 mm (0.04–0.08 in) wide and hang downwards. The dorsal sepal is pressed against the column which has broad wings, forming a bucket-like shape. The labellum is about 10 mm (0.4 in) long on the end of a strap-like stalk about 5 mm (0.2 in) long. The labellum is flattened and only about one-third of the outer part of the labellum is covered with glossy black glands or calli. Flowering occurs from October to December.
