Taxonomic notes: The most widely distributed variant of this species has a sessile perianth with a smooth tube but in the northern portion of S. Aust. a variant is found with a stipitate perianth and strongly ribbed tube; this variant is intermediate in morphology between O. salsuginosum and Sclerolaena urceolata, probably intergrading with the latter species. Typical O. salsuginosum appears to grade into O. acroptera var. deminuta.
