It occurs in South Australia, Victoria, New South Wales and the Australian Capital Territory. It has between three and six grass-like leaves and a flowering stem with up to four drooping, yellow flowers with dark streaks on the labellum. The flowers appear between September and November in its native range. Diuris behrii is a tuberous, perennial herb with between three and six grass-like, narrow linear leaves up to 200 mm (8 in) long. Up to four drooping, bright yellow flowers are borne on a flowering stem up to 500 mm (20 in) tall. The pedicel of each flower is enclosed in a bract. The dorsal sepal is egg-shaped, up to 17 mm (0.7 in) long and leans forwards. It has dark streaks similar to those on the labellum. The lateral sepals are greenish, linear to lance-shaped, up to 25 mm (1 in) long and turn downwards and parallel to each other. The petals spread sideways or droop and are narrow egg-shaped to elliptic, up to 25 mm (1 in) long on a green, stalk-like "claw". The labellum is up to 28 mm (1 in) long, often has brownish streaks, and has three lobes. The centre lobe is a broad wedge shape, often with irregular edges. The lateral lobes are small and oblong with toothed edges. There are two ridge-like calli about 5 mm (0.2 in) long near the mid-line of the labellum. Flowering occurs from September to November.
