Name derivation:
Tetratheca from the Greek 'tetra' meaning four; and 'theke' meaning case; referring to the 4 anther-loculi, the anthers are often four-lobed or four-celled. Halmaturina is derived from Halmaturus, a generic name once applied to kangaroos, and is from the Greek 'halme' meaning a leap or bound, and commonly used as an epithet for species from Kangaroo Island.
Endemic to South Australia and found only on Kangaroo Island.
Native. Common in South Australia.

Flowering between July to December.

Seed collecting:

Seed cleaning:
Place the capsules in a tray and leave to dry for a week. Then rub the dried 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.
