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. Maritima from the Latin ajective 'mare' meaning the sea; alluding to its coastal distribution.
Distribution:
Endemic to South Australia and found on the Eyre Peninsula, Yorke Peninsula, southern Flinders Ranges, Mount Lofty Ranges and Kangaroo Island, growing in sand in rocky areas, often near the coast. Close examination of herbarium specimens of Nicotiana maritima recorded from several sites in Victoria, has been shown these to be either misidentified, or geographically misplaced (misinterpretation of South Australian localities for like-named places in Victoria).
Status:
Native. Common in South Australia.
Plant description:
Erect herb to 0.7 m high, rarely taller with hairy leaves and stems, usually grey-or white-woolly. Leaves mostly basal to 22 cm long, ovate or elliptic, occasionally widely so or spathulate. Stem leaves narrow-elliptic or lanceolate, occasionally linear. Inflorescence erect panicule spike, usually with few-branching, sparse to dense hairs with tubular white flowers. Flowering most of the year but mainly in spring.
Fruit type:
Brown ellipsoid to ovoid capsule to 12 mm long.
Seed type:
Brown reniform seed to 1 mm long and 0.7 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 90%.
