About Pimelea trichostachya Lindl.
Pimelea trichostachya Lindl. is a slender, erect, semi-woody annual shrub that typically grows up to 75 cm (30 in) tall and has hairy stems. Its leaves are arranged alternately, shaped narrowly elliptic or linear, and measure 4–19 mm (0.16–0.75 in) long and 0.5–5 mm (0.020–0.197 in) wide. Leaves are either glabrous or sparsely hairy. The flowers are arranged in head-like spikes about 10 mm (0.39 in) long and wide, at the ends of branchlets, on a peduncle up to 19 mm (0.75 in) long, with each flower growing from a hairy pedicel. The flowers are bisexual, white or yellow, and densely covered with long, spreading hairs. Flowering occurs across most months of the year, with a peak flowering period from August to December. The fruit is green with a purplish tinge, and measures about 3 mm (0.12 in) long. This species, commonly called annual rice-flower, mainly grows in deep sand in mallee habitat. It occurs in all Australian mainland states and the Northern Territory, but is absent from most of northern Australia, the east and west coasts, and most of Victoria.
