Name derivation:
Drosera from the Greek 'droseros' meaning dewy, alluding to the glistening glandular hairs of the leaf laminae. Praefolia from the Latin 'prae' meaning before and 'folium' meaning leaf; alluding to the fact that the flowers appear on a terminal inflorescence before the leaves.
Distribution:
Endemic to South Australia and found on Kangaroo Island and the southern Mount Lofty Ranges.
Status:
Native. Rare in South Australia.
Plant description:
Small herb with a white stem tuber enclosed by multi-layered black sheath. Leaves annual, in a flat rosette, green or red, obovate to 16 mm long and 12 mm wide; margins involute when young. Inflorescence emerging before rosette, with 1–10 flowers; decumbent underneath the rosette foliage in fruit; sepals to 5 mm long and 1.5 mm wide, petals cuneate, truncate to shallowly notched to 8 mm by 4 mm, white. Flowering between March and July.
Fruit type:
Red-brown ovoid to globose capsule to 8 mm diameter.
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.
