Flowers 1–12, semi-nodding, 11–15 mm long, dark reddish brown with transparent areas in the galea; dorsal sepal with a short apical point; lateral sepals deflexed, conjoined part broadly ovate, 11–14 mm long, 12–14 mm wide, mostly flat, concave beneath the labellum, free point c. 6 mm long, tapered; petals slightly falcate, with a well-developed proximal flange.

Plants from the Little and Big Deserts are typically smaller plants (to 10 cm high) with fewer (1–3), slightly smaller, paler flowers. They have been described as a distinct species, Urochilus arbusculus D.L.Jones & C.J.French (Jones & French 2017), but no combination currently exists for these in Pterostylis. Both taxa are illustrated in VicFlora.
