Description

The flowers are yellow-to-orange, and born on setose scapes. The flower's involucre is also setose, and a campanulate shape, with an obtuse base. The involucre has at least two rows of terminal bracts around its apex, and usually some scattered parietal bracts along its length. The innermost terminal involucre bracts have an acuminate shape.

The leaves are lanceolate and can be either simple, or pinnate with linear-to-oblanceolate lobes. The margins of the leaf lobes are usually irregularly serrated. The upper leaf surface is usually rough and the lower surface is tomentose (white woolly).

In its growth form, G. ciliaris is a compact herbaceous perennial, and forms basal rosettes with only relatively short stems. The whole plant has a slightly sticky texture.[2]

Gazania serrata is very similar to a number of other Gazania species, including Gazania krebsiana, Gazania pectinata, Gazania linearis and Gazania rigida among others. Species boundaries between these are not clear, and they are frequently confused in practice.[3]
