Census of South Australian plants (external link)     [genus Vittadinia]
Name derivation:
Vittadinia named after Carlo Vittadini (1800-1865}, an Italian doctor and mycologist, author of several important works on Italian mushroom species. Gracilis from Latin meaning slender or graceful; referring to the often graceful and slender habit of the species.
Distribution:
Found in the southern part of South Australia, growing on a variety of soils in woodland and open land. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Uncommon in Tasmania. Common in the other states.
Plant description:
Perennial herb or subshrub to 40 cm high with erect, branching stems, produced annually from a woody stock, covered in fine white hairs, dense on stem, less so on leaves. Leaves flat to conduplicate, linear or narrowly lanceolate to spathulate, attenuate at the base, to 4 cm long and 7 mm wide, entire. Ray florets purple. Flowers throughout the year.
Fruit type:
Large fluffy creamy daisy head.
Seed type:
Yellow semi-flat long ovoid seed to 5 mm long and 1 mm wide, surface with parallel striation and hairs and pappus as long as seed.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect heads that are fluffy. Either pick off the whole heads or use your finger and pull off the seeds from the head. Mature seeds will come off easily.
Seed cleaning:
Place the heads in a tray for a week to dry. No cleaning is required if only pure seeds are collected. If heads are collected, then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be fat and hard. 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%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without any treatment.
