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. Flindersii named after the explorer Captain Matthew Flinders (1774-1814), after whom the Flinders Ranges were named.
Distribution:
Endemic to South Australia and restricted to the Flinders Ranges with outlying populations on Devils Peak and Olary Spur, growing on the upper slopes and ridges of higher hills.
Status:
Native. Rare in South Australia.
Plant description:
Multi- or single-stemmed trees to 10 m high with smooth, dull, grey bark, shedding in flakes to reveal a paler layer, some rough bark persisting at the base. Juvenile leaves elliptic to ovate. Adult leaves to 180 mm long and 30 mm wide,narrow-lanceolate to lanceolate, dull to slightly glossy, green to blue-green, veins clear. Flowers in groups of 3-7 in the axils of the leaves. Buds to 13 mm long and 6 mm wide, smooth, ovoid to obovoid, bud-cap cone-shaped, longer than the base; Flowers white. Flowering between September and November.
Fruit type:
Ovoid to broadly cone-shaped fruit to 8 mm long to 10 mm wide , smooth, disk level to ascending, valves triangular, exserted above the rim.
Seed type:
Dark brown to black irregularly pyramidal-shaped seed to 1.5 mm long and 1 mm wide, fine wrinkled.
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 95%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
