Darwinia capitellata

Darwinia capitellata is a many-branched shrub growing to 1.0 metre (3 ft) high with its leaves crowded near the ends of the branches. The younger branches have prominent oil glands. The leaves have distinct oil glands, a distinct stalk and are 2.5–4.5 millimetres (0.1–0.2 in) long and 0.5–1.0 millimetre (0.02–0.04 in) wide. The flowers are arranged near the ends of the branches in heads that are more corymb-like than those of other species of Darwinia. The two bracteoles around each flower are 2.3–4.0 millimetres (0.09–0.2 in) long, 0.5–1.0 millimetre (0.02–0.04 in) wide, thin and papery and fall off as the flower matures. The petals are egg-shaped, white 1.8–2.3 millimetres (0.07–0.09 in) long and enclose the 10 stamens, staminodes and the lower part of the style. The style which protrudes from the rest of the flower is 4–6 millimetres (0.16–0.24 in) long and has a band of hairs near its tip. Flowering occurs between August and November and is followed by the fruit which is a non-fleshy nut containing a seed 1 millimetre (0.04 in) long.

This darwinia grows on sandplains, sometimes on sandstone rock between Kalbarri National Park, Perenjori and Sandstone in the Avon Wheatbelt, Geraldton Sandplains, Mallee, Murchison and Yalgoo biogeographic regions.
