A hybrid between the native Nicotiana suaveolens and the introduced Nicotiana glauca. The calyx and corolla of Nicotiana × flindersiensis is intermediate between the two parental species, but the leaves have the shape of Nicotiana suaveolens and the terete petiole of Nicotiana glauca and the more or less equal stamens of Nicotiana glauca.
An unnamed hybrid is also known between Nicotiana suaveolens and N. velutina and has been recorded from Hattah Lakes area. Both it and N. × flindersiensis appear to be sterile F1 hybrids.
