Pest status
Eucalyptus sicilifolia is a tree to 10 m tall. The bark is persistent, dark grey ironbark, the smaller branches are smooth to about 2.5 cm diameter and cream in colour. The juvenile leaves are linear, glossy and distinctly discolorous, to 10cm long by 7mm wide, the petioles are 4mm long. The intermediate leaves are linear to 16cm long by 12mm wide, the petioles to 5mm long. The adult leaves are linear to narrow-lanceolate, acute or acuminate, falcate and glossy green, the same colour on both surfaces, 7 to 12 cm long by 6 to 16 mm wide, the petioles are 9 to 17 mm long. The lateral veins are well-spaced, regular, at 30 to 50 degrees to the midrib, finely regularly reticulate between. The intramarginal vein is distinct, 0.5 to 1 mm from the margin. The terminal inflorescence is compound, comprising 3 to 7 groups of flowers, the peduncles 2 to 8 mm long, the pedicels 2 to 5 mm long. The mature buds are ovoid to broadly fusiform, 4 to 5 mm long by 2 to 3 mm diameter. The fruits are ovoid, truncate, 4 to 5 mm long by 4 to 5 mm diameter, the valves are enclosed or at rim-level. The seeds are ovoid to ellipsoid, dull to sub-glossy, dark red-brown, shallowly reticulate.
Eucalyptus sicilifolia is distinguished within the E. paniculata group by the linear juvenile leaves, the glossy, lanceolate or distinctly falcate adult leaves, and the small buds and fruits. The only comparable bud and fruit size and shape in the group is E. beyeriana from NSW which has dull grey-green juvenile and adult leaves (Hill and Johnson, 1991).
