Name derivation:
Logania named after James Logan (1674-1751), an Irish born botanist who emigrated to North America, became Governor of Pennsylvania and wrote a book on the sexuality of plants. Minor from Latin meaning small; referring to its smaller flowers compared to Loganis crassifolia which it can be confused with.
Distribution:
Endemic to South Australia and found the Eyre Peninsula, Yorke Peninsula, southern Mount Lofty Ranges and the upper South-east, growing along the coast in open mallee communities on brownish sandy soil overlying limestone, or on flats adjacent to bare knolls.
Status:
Native. Rare in South Australia.
Plant description:
Prostrate or spreading shrub to 15 cm high and 1 m wide, dioecious, branches densely scabrous, rough to touch, older branches becoming almost glabrous. Leaves narrowly obovate to narrowly elliptic, to 28 mm long and 10 rnm wide, margin rough, flat, shiny green. Inflorescence compact terminal clusters with densely small white unisexual flowers. Flowering between September to October.
Fruit type:
Orange-brown ovoid capsule ovoid to 7 mm long and 5 mm wide.
Seed type:
Shiny black seed to 1.7 mm long and 0.8 mm wide, with a reticulated surface.
Embryo type:
Linear fully developed.
Seed collecting:
Collect maturing capsules, those that are fat, turning orange-brown in colour, have not open and contain hard black seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks for it to split. Then rub the capsules gently with a rubber bung 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.
