In the 1-fld peduncles, bibracteate at the top, and in the single stamen, this sp. agrees with S. singuliflorus (F. Muell.) Mattf. (Mniarum singuliflorum F. Muell. in Trans. Phil. Soc. Vict. 1, 1855, 13; S. mniaroides F. Muell. loc. cit. in synonymy); the Australian plant differs in the "constantly 5-cleft calyx".
