Basal to a group comprising C. burra and C. erythrochlamys#R. Hybridizes with C. erythrochlamys barlowi in NW of range (narrow zone between Port Nolloth and R Orange). Geographical variation marked in Northern Cape, with switch from coastal race codea to inland guttata remarkably sharp (complete replacement within a few kilometres) and few intermediates; otherwise, clinal variation between races broad in some areas; other named taxa are saldanhae, an intergrade between nominate and guttata; and calviniensis, intermediate between guttata and karruensis. Four subspecies recognized.
