Census of South Australian plants (external link)     [genus Nicotiana]
Name derivation:
Nicotiana named after Jean Nicot (1530-1600), a French Ambassador for the King of France to Lisbon in 1560, who sent the first tobacco plant to France. Simulans mean similar; possibly alluding to the similarity of this species to other Nictotiana species.
Distribution:
Found in the northern part od South Australia, growing in sandy and rocky soils, usually in shelter of boulders or in litter under trees, frequently near minor water courses. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Rare in Queensland. Common in the other states.
Plant description:
Herb to 1.2 m with glandular hairs.  Leaves mostly basal, to 23 cm long and 12 cm wide, elliptic, narrowly to broadly winged. Stem leaves narrowly ovate or elliptic. Inflorescence an erect panicle-like spike and tubular white flowers. Flowering between May and October.
Fruit type:
Brown ellipsoid to ovoid capsule to 13 mm long.
Seed type:
Brown reniform seed to 1 mm long and 0.5 mm wide, covered in small tubercules.
Embryo type:
Linear fully developed.
Seed collecting:
Collect mature capsules, those that are brown or turning a pale straw colour and contain brown seeds. Can collect individual capsules or break off the whole fruit spike.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From one collection, the seed viability was high, at 95%.
