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. Linifolia means having leaves like the genus Limum (flax).

Seed collecting:
Collect maturing capsules, those that are fat, turning orange-brown in colour, have not open and contain hard black seeds.

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.

From one collection, the seed viability was high, at 90%.
