Calochilus holtzei is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf which is fully developed at flowering time, 300–550 mm (10–20 in) long, 10–20 mm (0.4–0.8 in) wide and triangular in cross section. Between eight and twenty pale green to yellowish flowers with red markings, 20–23 mm (0.8–0.9 in) long and 10–15 mm (0.4–0.6 in) wide are borne on a flowering stem 500–900 mm (20–40 in) tall. The dorsal sepal is 7–9 mm (0.3–0.4 in) long and 5–7 mm (0.20–0.28 in) wide. The lateral sepals are a similar length but narrower. The petals are 5–7 mm (0.20–0.28 in) long and about 4 mm (0.2 in) wide. The labellum curves downwards and is 14–17 mm (0.6–0.7 in) long and 9–12 mm (0.4–0.5 in) wide. The base of the labellum has purple calli and two purple plates. The middle section has bristly, greenish white hairs up to 5 mm (0.2 in) long and there is a narrow tip about 3 mm (0.1 in) long. Flowering occurs from December to March but each flower only lasts two or three days.
