Ptilotus pyramidatus

Status: Critically Endangered on the EPBC Act list

The Pyramid Mulla-mulla is a small, probably perennial herb that grows to a height of about 5 cm. The erect stem is tufted, unbranched, finely striated, hairy and greyish in colour. The leaves are oblong to spoon-shaped and somewhat pointed, 1-1.5 cm long with a smooth margin. The leaves arising on the lower part of the stem have stalks, while the leaves on the upper stem are without stalks. The flowers are a greenish-yellow colour and arranged in dense, pyramid-shaped spikes about 2.5 cm long. The flowers are either single, or two or three together at the ends of the stems. Individual flowers are about 1 cm long. The fruits are small and dry with a single seed inside. Flowering occurs in early October.

    The adverse impact of these changes on the hydrological regime of the GBW will be exacerbated by the trend towards a drier climate that is now evident in the Swan Coastal Plain.
