Thysanotus lavanduliflorus

Thysanotus lavanduliflorus is a tufted perennial herb with a small rootstock and tuberous roots. Its two or three leaves are narrowly linear, about 60–70 mm (2.4–2.8 in) long but that wither before flowering. The flowers are borne in umbels of four or five, each flower on a pedicel 8–10 mm (0.31–0.39 in) long. The flowers are purple, the perianth segments 11–15 mm (0.43–0.59 in) long. The sepals are narrowly lance-shaped, about 2 mm (0.079 in) wide with a point on the end and the petals are oblong, 4.0–4.5 mm (0.16–0.18 in) wide with a fringe about 1.5 mm (0.059 in) long. There are six stamens, the outer anthers about 2.5–3 mm (0.098–0.118 in) long and the inner anthers about 6 mm (0.24 in) long, curved and twisted. The style is curved, 6–8 mm (0.24–0.31 in) long. Flowering occurs in November and December.

This species of Thysanotus grows in open mallee and low woodland in sandy to loamy soils between Hyden and Newdegate in the south-west of Western Australia, in the Mallee bioregion.
