A variable species with cladodes resembling those of B. bracteosa F. Muell. ex Benth., but lacking the spirally imbricate bracts of the latter which conceal the pedicel and the upper 2 calyx teeth relatively larger and more falcate than the more uniform calyx teeth of the latter. From B. scleropendria (Andrews)Smith it differs mainly in having smaller flowers.
