Description

Darwinia helichrysoides is a slender, erect shrub that typically grows to a height of 20–50 cm (7.9–19.7 in). Its leaves are linear, spreading, triangular to round in cross-section, 4–6.5 mm (0.16–0.26 in) long. The flowers are arranged in groups of about 4 surrounded by many red and green, egg-shaped to lance-shaped bracts forming an involucre nearly 25 mm (0.98 in) long. The sepals are more than 6 mm (0.24 in) long and joined at the base but without prominent ribs and the petals are about 2 mm (0.079 in) long. Flowering occurs from August to November. [2] [3] [4]

Taxonomy

This species was first formally described in 1857 by Carl Meissner, who gave it the name Genetyllis helichrysoides in the Journal of the Proceedings of the Linnean Society, Botany , from specimens collected by James Drummond. [4] [5] In 1865, George Bentham changed the name to Darwinia helichrysoides in the Journal of the Proceedings of the Linnean Society, Botany. [6] The specific epithet (helichrysoides ) means " Helichrysum -like". [7]

Distribution and habitat

Darwinia helichrysoides is found in the uplands in a small area between Coorow and Dandaragan where the Geraldton Sandplain meets the Swan Coastal Plain where it grows in gravelly lateritic soils. [2]
