About Cyanothamnus ramosus Lindl.
Cyanothamnus ramosus Lindl. is a slender, erect, mostly glabrous woody shrub that reaches 30 centimetres (10 inches) in height. Its leaves are pinnate, measuring 10–30 mm (0.4–1 in) in overall length, with between three and seven leaflets borne on a 1–11 mm (0.039–0.433 in) long petiole. Individual leaflets are 5–15 mm (0.20–0.59 in) long. Up to three flowers grow in leaf axils, each on a pedicel 2–15 mm (0.079–0.591 in) long. This species has four thick, glabrous, egg-shaped sepals that are 1.5–5 mm (0.059–0.20 in) long. The petals are broadly elliptic, 3–5 mm (0.12–0.20 in) long, white with blue or pale green backs, and are prominently glandular. Flowering takes place from May to October. Cyanothamnus ramosus grows on slopes and hillsides, and sometimes in disused gravel pits. It is widespread in southwestern Western Australia, ranging from near Shark Bay to near Esperance. Three subspecies have distinct ranges: subspecies anethifolius occurs between the Murchison River, the Stirling Range and Cape Le Grand; subspecies lesueuranus is only known from near Mt Lesueur; and subspecies ramosus occurs mainly in the Darling Range.
