Prasophyllum beatrix, commonly known as Marung leek orchid, is a species of orchid endemic to eastern Australia. It has a single tubular leaf and up to thirty five scented flowers with yellowish-green or purplish markings and is mainly confined to New South Wales.
Prasophyllum beatrix is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped, dark green leaf up to 600 mm (20 in) long and 2–8 mm (0.08–0.3 in) wide at the base, with the free part up to 250 mm (10 in) long. Between eight and thirty five scented white flowers with yellowish-green or purplish markings are crowded along a robust flowering spike 50–120 mm (2–5 in) long. As with others in the genus, the flowers are inverted so that the labellum is above the column rather than below it. The dorsal sepal is lance-shaped to narrow egg-shaped, 10–12 mm (0.4–0.5 in) long. The lateral sepals are a similar size to the dorsal sepal and are usually free each other. The petals are linear to lance-shaped and 10–14 mm (0.4–0.6 in) long. The labellum is white, 12–15 mm (0.5–0.6 in) long, turns upwards at more than 90° and has crinkled edges. Flowering occurs from September to October.[2][3]
