Calothamnus robustus

Calothamnus robustus is a compact, erect shrub growing to about 0.5–1.5 metres (1.6–4.9 ft) tall. Its leaves are circular in cross section but are not prickly. The flowers are red and arranged in clusters of 3 to 5. Unlike some others in the genus, the flowers and fruit are never buried in corky bark. The flowers have 4 sepals which are densely hairy on their outer surface. There are 4 petals and the stamens are joined in 4 narrow, claw-like bundles which are all roughly the same length. Flowering occurs mainly from September to November, sometimes in other months and is followed by fruits which are woody capsules. The fruiting capsules have two prominently thickened lobes.
