Taxonomic notes: The Australian populations have been placed by many authors under N. schoberi L., a species extending from European Russia to Central Asia. A full assessment of the differences of the two very closely allied species is needed. The putamen of N. schoberi seems to be smaller than that of N. billardierei, and its leaves are oblong-spathulate to oblong. The chromosome numbers recorded for N. schoberi are 2n = 24, those for N. billardierei are 2n = 48. A thorough comparison of the western and eastern coastal and inland populations (including habit characteristics) is desirable as they may be taxonomically distinct. Some flowers appear to be unisexual, at least functionally, and some plants may be male only. The sex distribution needs further investigation.
