Census of South Australian plants (external link)     [genus Alyxia]
Name derivation:
Alyxia from the Greek 'alysis' meaning a chain or an escape, may refer to the chain fruit or indicate the remote areas in which it was found. Buxifolia from 'buxus', the genus of ancient box tree and the Latin 'folium' meaning leaf, referring to the species having leaves like the boxwood.
Distribution:
Found mainly in coastal regions of South Australia but can be inland on Eyre Peninsula and Yorke Peninsula. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Dense perennial shrub to 2 m tall but on the coast, often stunted to less than 50 cm, with thick, smooth, green and shiny lance-shaped leaves arranged opposite to each other. Flowers are white and tubular, with five petals arranged almost at right angles to each other. Flowering between October and February.

Round fleshy red berries to 10 mm across.
Seed type:
Yellow woody elipsoid seed to 10 mm across.
Embryo type:
No information available.
Seed collecting:

Seed cleaning:
Place the fruits in a bucket of water and rub the flesh off the fruits with your hands then rinse and drain leaving just the clean seeds behind. Place the seeds on paper towels and leave to dry overnight. 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 one collection, the seed viability was high, at 80%.
Seed germination:
This species has a combination of physical (hard seed coat) and physiological dormancies that needs to be overcome for the seed to germinate.
