Prasophyllum pyriforme
Prasophyllum pyriforme, commonly known as the graceful leek orchid is a species of orchid species endemic to eastern Australia. It has a single tubular leaf and up to fifty greenish flowers with a pink or white labellum. As with others in the genus, the labellum is above the column rather than below it. Description Prasophyllum pyriforme is a terrestrial, perennial, deciduous, herb with an underground tuber and a single smooth dark green, tube-shaped leaf long and in diameter near its reddish base. Between thirty and fifty greenish or mauve flowers are crowded on a flowering stem long. The ovary is long, the petals are long and the lateral sepals are long, erect, linear to lance-shaped and fused at their sides for most of their length. The labellum is long, curves upwards to almost touch the lateral sepals and is pink or white with wavy edges. The callus in the centre of the labellum is greenish, wrinkled and extends almost to the tip of the labellum. Flowering occurs in November and December. Taxonomy and naming Prasophyllum pyriforme was first formally described in 1933 by Edith Coleman and the description was published in The Victorian Naturalist from a specimen collected near Doncaster.
