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. Species Strzelecki Creek refers to the collection location. The species was initially referred to as Nicotiana exigua (from the Latin 'exiguus' meaning scanty, slender, possibly referring to the smaller and more slender corolla tube (flower)) but the material is not N. exigua when compared to the type sheet at the Herbarium of South Australia or the isotype at Kew. Nicotiana exigua is considered a synonym of N. suaveolens by most authors, but Mark Chase (per. comm.) consider N. exigua to be a distinct species and that N. sp. Strelecki Creek is neither N. exigua or N. suaveolens but a distinct species with lots of hairs and not nearly glabrous as in N. exigua and N. suaveolens.

Found in the north-east corner of South Australia, growing on bank of creeks.
Native. Uncommon in South Australia.
Plant description:
Herb to 50 cm high, hairy or subglabrate with rough hairs along leaf surface and stems. Leaves thin, slightly fleshy, to 18 cm long and 6.5 cm wide, margin undulate with main lateral and lesser veins distinct, basal leaves rosette at first, transition to lower cauline later becoming less obvious, elliptic-acute, cauline leaves elliptic, ovate or broad lanceolate. Inflorescence long erect spreading spike, repeatedly branching, with tubular flowers, white inside and cream, green or purple tinged outside, held upward or subhorizontal. 
Fruit type:
Brown conic-ovate capsule to 8 mm long.
Seed type:
Brown reniform seed to 0.7 mm long and 0.5 mm wide, covered in wrinkles.
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 100%.
