Series Albae 
Bark wholly smooth, shed regularly in thin flakes, trunks usually at first salmon or 
orange, becoming 'powdery' white. Juvenile leaves becoming disjunct very early 
(except in neotenous species), broad-lanceolate or ovate to orbicular. Outer calyptra 
shed early in development. Inner calyptra ± hemispherical, ± thickened. Stamens 
inflexed in bud. Nectary disc absent in bud, narrowed in fruit. Valves ± thickened. 
Seeds brownish-black, ragged and deeply reticulate. 
Distributed almost entirely within savanna woodland country of the monsoon tropics, 
a single species occurring further south on the Queensland coast (E. hnllii Brooker near 
Bundaberg). Four subseries are recognised. 
Subseries Albosae 
Subseries Mooreanosae 
Subseries Herbertianosae 
Subseries Hallianosae 
Juvenile leaves more or less orbicular, disjunct. 
Juvenile leaves orbicular, opposite 
Juvenile leaves lanceolate to ovate, disjunct. 
Juvenile leaves large, lanceolate to ovate, falcate, disjunct. 
Subseries Mooreanosae 
Adult leaves opposite, orbiculate. 
Although apparently paralleling the neotenous condition occurring in some other 
eucalypt groups, this condition is not strictly neotenous in this group. In this case, the 
first few pairs of juvenile leaves are opposite, broad-lanceolate and petiolate; later 
juvenile leaves remain opposite but become orbiculate (and sessile in £. mooreana), and 
adult leaves retain the latter condition.

21 Aug 1967 (holo NSW). 
Tree to 12 m tall, usually less than 6 m, often of twisted habit. Bark smooth throughout, 
powdery, white or salmon, orange or pink, shedding in large plates or flakes. Juvenile 
leaves lanceolate to ovate, dull grey green, petiolate. Adult leaves opposite to 
subopposite, ovate to suborbiculate or orbiculate, not falcate, obtuse or rounded,
