A native of W. Australia. It is at least the equal of C. citrinus in the beauty of its spikes. As seen in cultivation the leaves are usually of a rather glaucous grey-green, but this is apparently not a constant character of the species. Some plants in cultivation as “C. speciosus” are a form of C. citrinus.
