About Prasophyllum gracile Lindl.
Prasophyllum gracile Lindl. is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a single smooth, tube-shaped leaf that is usually green, sometimes reddish. The leaf measures 80–150 mm (3–6 in) long and around 2 mm (0.08 in) in diameter near its base. Between five and forty or more flowers grow on a flowering spike that reaches 60–200 mm (2–8 in) in height. The flowers are yellowish-green, sometimes purplish, 7–10 mm (0.3–0.4 in) long and about 5 mm (0.2 in) wide. The ovary is oval-shaped, about 3.5 mm (0.1 in) long. The dorsal sepal is narrow egg-shaped or lance-shaped, around 5 mm (0.2 in) long, concave and roughly pointed. The lateral sepals are narrow lance-shaped, about 6 mm (0.2 in) long, joined along about half their length, with erect pointed tips around 2 mm (0.08 in) long. The petals are about 4 mm (0.2 in) long, blunt-tipped, and curve inwards. The labellum is egg-shaped to lance-shaped, about 3 mm (0.1 in) long and 2 mm (0.08 in) wide, with slightly wavy edges. It curves upwards to almost reach the lateral sepals. Flowering takes place from July to November. This species, commonly called the little laughing leek orchid, most commonly grows in shallow soil pockets on granite outcrops, though it can also be found in other habitats. It occurs between Shark Bay in the north and Eyre on the Great Australian Bight.
