Prasophyllum hectorii

Prasophyllum hectorii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single dark green to yellowish-green, tube-shaped, rush-like leaf which is usually taller than the flowering stem. The flowering stem emerges from the leaf about one-third of the leaf's length from its base. Between ten and eighty scented, well-spaced flowers are arranged along a flowering spike about 80 mm (3 in) long. The flowers are yellow to greenish, 5–8 mm (0.2–0.3 in) long with a mostly white 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 broadly egg-shaped, dished, 6–8 mm (0.2–0.3 in) long and the lateral sepals are narrow oblong, slightly longer than the dorsal sepal and free from each other. The petals are slightly shorter and thinner than the lateral sepals. The labellum is egg-shaped and turns sharply upwards about halfway from its base. The edges of the labellum are white and wavy and there is a light green callus in the centre of the labellum. Flowering occurs from December to February.

Prasophyllum hectorii is found on the North and Chatham Island islands where it grows in wetlands, usually in or near slow-flowing streams, often with sedges.
