Description

''Hemiphora elderi'' is shrub which grows to a height of about with several branches arising from a single main stem. The leaves are pale green, linear to lance-shaped, but often appear almost cylindrical because their edges are strongly turned under. The leaves are long, wide, densely covered with white, woolly hairs, warty on the upper surface and with the lower surface often obscured by the rolled leaf edges. The flowers are arranged in short, leafy, spike-like clusters near the ends of the branches, on short woolly stalks. The flowers are surrounded by woolly, leaf-like
