About Prasophyllum brownii Rchb.f.
Prasophyllum brownii Rchb.f. is a terrestrial, perennial, deciduous herb with an underground tuber. It produces a single smooth, light green, tube-shaped leaf, which measures 600–1,000 mm (20–40 in) long and 5–15 mm (0.2–0.6 in) in diameter near its base. Between thirty and eighty or more flowers are arranged along a flowering spike that reaches 400–1,200 mm (20–50 in) in height. The flowers are light green, white, and fawn-coloured, and are 10–15 mm (0.4–0.6 in) long and 10–12 mm (0.4–0.5 in) wide. Like other species in the genus Prasophyllum, the flowers of this species are inverted, meaning the labellum sits above the column instead of below it. The dorsal sepal curves upwards, and the petals face forwards, giving the flowers a cup-shaped appearance. The lateral sepals are erect and joined to each other along their sides. The labellum is broad and turns upwards, but does not bend as sharply as the labellum of other leek orchids, and it has a frilly edge. Flowering occurs between November and January. This species is commonly known as the Christmas leek orchid. It grows in a wide variety of habitats, including wet areas, forest, and woodland, and is often found growing on rotting logs and stumps. It occurs in the region between Perth and Esperance.
