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. Yalatensis named after the Yalata Community on the Nullarbor Plain of South Australia, near where the type specimen was collected.
Distribution:
Found on the Nullarbor, western Eyre Peninsula, single record on Yorke Peninsula and the Cooke Plains in South Australia, growing in tall dense mallee to low open mallee vegetation on calcareous shallow sands to sandy loams over limestone. Also found in Western Australia.
Status:
Native. Common in South Australia. Common in Western Australia.
Plant description:
Multi-stemmed often dense-crowned mallee to 7 m tall with rough, fibrous, pale to dark grey bark on lower stems and smooth, yellow-brown to grey to creamy bark above. Juvenile leaves ovate to broad-lanceolate, dull, blue-green. Adult leaves to 113 mm long and 25 mm wide, lanceolate, dull, blue-green to greyish. Flowers axillary in groups of 7-11. Buds to 8 mm long and 4 mm wide, bud-cap cone-shaped to horn-shaped, equal to or longer than the base. Flowers creamy-white appearing in summer.
Fruit type:
Cone-shaped fruit to 6 mm long and 6.5 mm wide, disc level to descending, valves 3 or 4 below the rim.
Seed type:
Brown ovoid seed to 1.7 mm long and 1 mm wide, with 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 viability:
From one collection, the seed viability was high, at 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
