Calothamnus quadrifidus subsp. seminudus is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to other subspecies of Calothamnus quadrifidus except that its leaves are linear and somewhat rough and scaly and the stamen bundles are relatively long.
Description
Calothamnus quadrifidus subsp. seminudus is an erect or spreading shrub which sometimes grows to a height of 2.0 metres (7 ft) and lacks a lignotuber. Its leaves are crowded, flat and linear or very narrow egg-shaped with the narrower end towards the base. They are 10–20 millimetres (0.4–0.8 in) long and 0.8–1.5 millimetres (0.03–0.06 in) wide.[1]
The flowers are red and arranged in clusters, usually on one side of the stem amongst the older leaves. The
