Census of South Australian plants (external link)     [genus Eucalyptus]
Name derivation:
Eucalyptus from the Greek 'eu' meaning well and 'calyptos' meaning covered; alluding to the cap or lid which covers the stamens in the bud. Socialis from the Latin 'socialis ' meaning friendly; alluding to the species being associated with other eucalyptus species.
Distribution:
Found in the drier regions throughout the eastern part of South Australia, growing in mallee vegetation on very calcareous, pale grey sandy loams to red loams over limestone. Also found in New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Multi-stemmed mallee to 12 m high with rough, stingy to flaky-fibrous, pale grey to brown bark on lower stems and smooth, tan to pinkish-grey to cream bark above. Young branchlets not waxy. Juvenile leaves ovate to lanceolate, sometimes waxy, dull, blue-green to greyish. Adult leaves to 127 mm long and 21 mm wide, narrow-lanceolate to lanceolate, dull to slightly glossy, blue-green. Flowers in groups of 7-11 in leaf axils. Buds to 13 mm long and 5.5 mm wide, rarely waxy, bud-cap horn-shaped, equal in width and longer than the base. Flower creamy-white appearing in spring. This subspecies is distinguished from the other three subspecies that occurs in South Australia by its distribution, relatively small, dull, blue-green adult leaves, creamy white flowers, relatively small buds and fruits and usually not-waxy adult features.
Fruit type:
Round to barrel-shaped fruit to 7 mm long and 7 mm wide, waxy when young, disc descending, valves 3-5 below rim.
Seed type:
Brown ovoid seed, with finely reticulated surface.
Embryo type:
Folded.
Seed collecting:
Collect mature fruits that are dark and hard (difficult to break with a finger nail), with the valves un-open any time of year.
Seed cleaning:
Leave the fruits in a breathable container in a dry room for one to two weeks. 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 (soft) and frass (hard) usually distinguishable from each other but can be very similar in shape and colour. 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 germination:
Seeds are non-dormant, viable seed should germinate readily.
