Botanical descriptions of Eucalypti

Eucalyptus globulus (Labillardiere) —Tall, erect tree, even in exposed situations, tending to preserve a preponderating main-stem till the high forest age is reached, the branches few and acutely diverging; bark deciduous. Mature foliage alternate, stalked, lanceolate, acute, oblique, 6 to 12 inches long, 1 to 2 inches wide.
Flowers solitary in the leaf axils. Outer operculum smooth, shed while the bud is approaching maturity ; calyx and inner operculum rough, warted, and obscurely four-ribbed ; mature calyx about | inch in diameter; anther-cells parallel. Fruit broadly obconic, | to 1 inch in diameter ; capsule slightly protruding ; valves obsolete. In Eastern Victoria the common form of this tree bears a three-flowered umbel in the axil, the flowers being half the size recorded in the type, and less warted. In Tasmania, where this species and E. viminalis are mixed, a form will occasionally be found consisting of odd trees in which the flowers are in threes, the operculum and fruit quite smooth, and the fruit about three quarters to one inch in diameter, the valves much protruding.
This, though very close to the Victorian form, may be a hybrid.
