Prasophyllum amoenum (Prasophyllum amoenum)
Description
Prasophyllum amoenum, commonly known as the dainty leek orchid or Snug leek orchid, is a species of orchid endemic to Tasmania. It has a single tubular, green leaf with a purplish base and between five and twelve light green, dark brown and white flowers. In 2007, the entire population was estimated to be about 600 plants.Prasophyllum amoenum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single tube-shaped leaf, 120–300 mm (5–10 in) long and 2–4 mm (0.08–0.2 in) wide, the free part 40–60 mm (1.6–2.4 in) long. Between five and twelve flowers are loosely arranged along a flowering spike 30–50 mm (1–2 in) long reaching to a height of 150–350 mm (6–10 in). The flowers are greenish, 8–10 mm (0.3–0.4 in) long and 7–9 mm (0.3–0.4 in) wide with dark brown lateral sepals, white and red petals and a white or pinkish labellum. 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 a narrow egg-shape to lance-shape, 8–10 mm (0.3–0.4 in) long and about 3 mm (0.1 in) wide. The lateral sepals are up to 8–10 mm (0.3–0.4 in) long and spread apart from each other. The petals are narrow linear to lance-shaped, 7–9 mm (0.3–0.4 in) long and about 2 mm (0.08 in) wide. The labellum is 8–10 mm (0.3–0.4 in) long and turns upwards, sometimes extending above the lateral sepals and its edges are wavy. Flowering occurs in January.
