Census of South Australian plants (external link)     [genus Logania]
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. Ovata from the Latin 'ovatus' meaning ovate; referring to the shape of the leaves.
Distribution:
Found on the Eyre and Yorke Peninsulas, Kangaroo Island and the South-east in South Australia, growing in near-coastal habitat in shrubland or open Mallee on sandy loams to heavier clay-rich soils. Also found in Victoria.
Status:
Native. Common in South Australia. Rare in Victoria.
Plant description:
Erect shrub to 2 m high, dioecious, stems glabrous to minutely hairy. Leaves ovate to broadly ovate, to 25 mm long and 18 mm wide, glabrous to minutely hairy, flat, sessile or with very short stalk. Inflorescence a compact clusters of white unisexual flowers on long peduncles. Flowering between August and November.
Fruit type:
Orange-brown capsule to 6 mm long and 3 mm wide.
Seed type:
Black convex seed to 1.6 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.
Seed viability:
From two collections, the seed viability was average to high, ranging from 65% to 100%.
