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. Eremicola from the Greek 'eremia' meaning desert and 'cola' meaning dwelling; referring to its distribution in the Great Victoria Desert. Peeneri is of Aboriginal origin.
Distribution:
Found in the western part of South Australia, in the Great Victoria Desert, growing on deep red loams or sand overlying limestone in flats and swales between sand ridges. Also found in Western Australia.
Status:
Native. Rare in South Australia. Uncommon in Western Australia.
Plant description:
Multi-stemmed mallee to 9 m high with rough, stringy-fibrous, grey bark on lower stems and smooth, pinkish-grey over cream to white, often powdery bark above. Juvenile leaves elliptical first becoming linear, slightly blue-green. Adult leaves to 133 mm long and 21 mm wide, narrow-lanceolate, dull to slightly glossy, blue-green. Inflorescences in groups of 9-13 in the axils of the leaves. Buds to 8 mm long and 4 mm wide, cylinder-shaped, bud-cap long cone-shaped longer than the base. Flowers white appearing sporadically after rain. This subspecies differ from the other subspecies found in South Australia, E. eremicola ssp. eremicola which has highly glossy green adult leaves.
Fruit type:
Round fruit to 5.5 mm long and 7 mm wide, disc descending, valves 3 or 4, tips joined when immature, then enclosed below rim with a pointy tip.
Seed type:
Brown elliptical to ovoid seed to 1.5 mm long and 1.2 mm wide.
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.
