The genus Codonorhiza derives its name from the shape of its corms, which resemble a bell, with the name meaning “bell-shaped root.” The species name corymbosa is based on the term “corymb,” referring to a flat-topped flower cluster where the outer flower stalks are longer than the inner ones. The common names “cabong” and “chabi” were used by the Khoisan hunter-gatherers to refer to several species of Lapeirousia.

DNA analysis revealed that the genus Lapeirousia, as previously defined, did not share a single ancestor. As a result, it was divided in 2015 into four separate genera: Lapeirousia and three newly described genera—Codonorhiza, Schizorhiza, and Psilosiphon.

Codonorhiza is endemic to the Western Cape of South Africa and consists of seven species.

Codonorhiza corymbosa, synonymously known as Ixia corymbosa, Ixia crispifolia, Lapeirousia corymbosa, Meristostigma corymbosum, Ovieda corymbosa or Peyrousia corymbosa and commonly known as Bloucabong, Koringblom or Koringblommetjie, is a South African endemic species found in the Western Cape province from Piketberg to Agulhas, growing on sandy and granite slopes amongst fynbos. Codonorhiza corymbosa grows to 15cm tall. It has a branched inflorescence of blue to purple flowers with white markings in the center. It flowers from spring to summer.
