Pterostylis hispidula, commonly known as the small nodding greenhood or box greenhood, is a plant in the orchid family Orchidaceae and is endemic to eastern Australia. Nodding greenhoods have flowers which "nod" or lean forwards, have a deeply notched sinus and a curved, hairy labellum. This species is similar to Pterostylis nutans but is smaller and the flowers do not lean as far forward as in that species.
