Genoplesium morrisii (Genoplesium morrisii)
Description
Genoplesium morrisii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf 200–250 mm (8–10 in) long and fused to the flowering stem with the free part 10–22 mm (0.4–0.9 in) long. Between three and fifteen dark purplish-black or green and purple flowers are crowded along a flowering stem 35–50 mm (1–2 in) tall. The flowers are about 11 mm (0.4 in) long and 9 mm (0.4 in) wide and are inverted so that the labellum is above the column rather than below it. The dorsal sepal is egg-shaped, 5–6 mm (0.20–0.24 in) long and about 2.5 mm (0.1 in) wide with dark purpish-black stripes. The lateral sepals are linear to lance-shaped, about 7 mm (0.3 in) long, 1.5 mm (0.06 in) wide and spread apart from each other. The petals are lance-shaped to egg-shaped, about 4 mm (0.2 in) long and 1.5 mm (0.06 in) wide with a pointed tip. The labellum is lance-shaped, to narrow egg-shaped, about 4 mm (0.2 in) long, 1.5 mm (0.06 in) wide and vibrates in the slightest breeze. The sides of the labellum are lines with many coarse, spreading cilia and there is a narrow oblong callus in the centre of the labellum and extending about half way to its tip. Flowering occurs between January and April.
