The spreading lignotuberous shrub typically grows to a height of 0.5 to 2 metres (1.6 to 6.6 ft).[1] It can have a rigid multi-stemmed habit with ferruginous branchlets and young leaves. The mature leaves have a linear to narrowly obovate shape with a length of 4.5 to 23 centimetres (1.8 to 9.1 in) and a width of 0.2 to 1.4 cm (0.08 to 0.55 in) with three to five lobes that are 3.5 to 8.5 cm (1.38 to 3.35 in) wide.[2] It produces brown-red flowers from September to December.[1] The umbelliform inflorescences contain between two and ten flowers with obscure rachis and on pedicels that are 2 to 5 millimetres (0.079 to 0.197 in) in length. The black fruits that form afterward have an obliquely ovate shape and are 2 to 3.5 cm (0.79 to 1.38 in) in length with a width of 0.9 to 1.3 cm (0.35 to 0.51 in). The seeds with in are obliquely elliptic with a length of 1.2 to 2 cm (0.47 to 0.79 in) and have a narrow wing down one side.[2]
Taxonomy
The species was first formally described by the botanist Robert Brown in 1810 as part of the work On the natural order of plants called Proteaceae as published in Transactions of the Linnean Society of London. Several synonyms are known including Conchium ceratophyllum, Hakea acanthophylla, Hakea laciniosa and Hakea cervina among others.[3]
The species name is taken from the Greek words cerato meaning horn and phyllo meaning leaf referring to the shape of the leaves.[2]
