Name derivation:
Babingtonia named after Charles Babington (1808-1895), an English professor of botany. Behrii named after Hermann H. Behr (1818-1904), a German-American doctor, entomologist and botanist, who collected in South Australia.
Distribution:
Grows in a range of habitats in low rainfall areas on Eyre Peninsula, Murray and upper South-east regions of South Australia with isolated populations in the north-west corner, growing on sand rises and dunes and granitic soils, in mallee and heath communities. Also found in Western Australia, Northern Territory, New South Wales and Victoria.
Status:
Native. Common in South Australia. Very rare in the Northern Territory. Rare in New South Wales. Common in the other states.
Plant description:
Shrub to 2.5 m tall, with erect branches. Leaves opposite, semiterete, usually with a fine recurved point, to 7mm long. Flowers solitary or rarely in pairs, axillary, 5 white petals. Flowering between September and January.
Fruit type:
Woody grey brown capsule with 3-5 valves.
Seed type:
Seeds are angular, pale brown, less than 1mm.
Seed collecting:
Collect mature capsules, those that are hard with non-open valves.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week or two. This allows the valves on the fruit to open and release the seeds. Separate the seeds by placing all the materials into a bucket and shaking it to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds and frass usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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 95%.
