Thysanotus pseudojunceus

Thysanotus pseudojunceus is a perennial herb with a short rhizome, fibrous roots and usually no leaves, but occasionally four or five terete leaves 35–50 mm (1.4–2.0 in) long. The stems are low-lying and branched, 300–360 mm (12–14 in) long. The flowers are borne in umbels of two to five, each flower on a pedicel 8–9 mm (0.31–0.35 in) long. The flowers are purple, the perianth segments 10–12 mm (0.39–0.47 in) long. The sepals are lance-shaped, about 3 mm (0.12 in) wide and the petals are elliptic, about 5 mm (0.20 in) wide with a fringe 2.5–4 mm (0.098–0.157 in) long. There are six stamens with twisted anthers, the outer anthers 3 mm (0.12 in) long, the inner ones 6 mm (0.24 in) long and curved. The style is curved, about 7 mm (0.28 in) long. Flowering occurs from November to December or January, and the seeds are elliptic, about 2 mm (0.079 in) long and 1.0–1.5 mm (0.039–0.059 in) in diameter with a stalked, dull orange aril.

This species of Thysanotus grows in clayey or peaty sand, loam or on granite, often in winter-wet places, in jarrah (Eucalyptus marginata) forest, between Albany and the mouth of the Blackwood River in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
