SA Flora:
Flora of South Australia Edition 5
Name derivation:
Drosera from the Greek 'droseros' meaning dewy; alluding to the glistening of the glandular leaf laminae. Glanduligera meaning gland-bearing; referring to the glandular scapes.
Distribution:
Found across the southern part of South Australia, from the Flinders Ranges, Eyre Peninsula to the lower South-east, growing in areas with temporary soil moisture during the cooler months. 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:
Ephemeral herb with short stems. Leaves in a convex rosette, lamina circular, very concave, to 12 mm diameter, abruptly narrowed to flat petiole to 8 mm long and 4 mm wide, stipules to 2 mm long, fused to base of petiole. Inflorescences 1–4, to 5 cm long, glandular, pedicels to 10 mm long, reflexed after flowering. Calyx to 5 mm long, deeply divided into ovate lobes, lobes laciniate. Petals to 5 mm long, orange or red. Flowering between August and November.
Fruit type:
Brown globose capsule to 4.5 mm diameter, finely reticulate, enclosed in densely hairy sepals.
Seed type:
Black spheroidal seed to 0.4 mm diameter, with a worty surface.
Seed collecting:
Collect mature capsules, those that are fat, hard, turning brown and contain black seeds inside.
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%.
