Taxonomic studies in the genus Lessertia have revealed that L. rigida represents a mixed species concept comprising two distinctly different elements. The specific epithet is linked to a largely overlooked type specimen collected by Carl Thunberg in the Cape of South Africa during the latter part of the eighteenth century which represents one element of the mixed species concept. Due to nomenclatural priority and correct application of the name, the description of a new species is necessary to accommodate the second element included in the mixed species concept. This paper aims to clarify the identity of L. rigida and to describe the new species meyeri.
