Section Tranversaria 
Adult leaves strongly dorsiventral ('discolorous'), variously hypostomatic to partly to 
± completely amphistomatic; lateral veins closely spaced, parallel, at a high angle to 
the midrib (> 50°). Anthers versatile, oblong, opening by parallel slits. 
The group Transversaria as defined here comprises 23 species. Most species occur in 
tall, wet forests of the coast and ranges of eastern Australia, with one species in wet 
forests of south-western Western Australia, one extending to New Guinea and three 
endemic to islands of south-eastern Indonesia and East Timor 
Species of this group are abundant around Port Jackson, and were consequently 
recognised very early in the history of Australian botany. Four species were described 
before 1800 by Smith (1790, 1795, 1797). Nine species were recognised by Bentham 
(1867), in six different groups (six of these were species of Transversaria sens, strict., 
placed by him in three subseries of his series Normales). He also reduced £. punctata 
DC. to synonymy with E. tereticornis Sm. 
Maiden ( Crit. Revis. Eucalyptus 1903-1933, 6: 355) recognised 17 species, placing them 
(with other taxa) in section Macrantherae subsection Tereticornes (excepting £. pellita 
F. Muell., which he placed in subsection Longiores series Non-Corymbosae). He went on 
to place most of these in his seed series Lepidotae-Fimbriatae. Neither Maiden nor 
Bentham considered critical features of leaf morphology in their classifications. 
Blakely (1934) recognised a series Transversae based on leaf venation, and made up of 
all then known taxa that we now place in Transversaria. Twenty species were included, 
several of which have since been reduced to synonymy. Blakely also included 
£. cladocalyx F. Muell. The latter was excluded from the series by Pryor and Johnson 
(1971), who otherwise included the same taxa as Blakely. Nomenclatural problems 
with taxa in the Indonesian Islands were resolved with the description of E. urophylla 
by Blake (1977), and further taxonomic difficulties in this group were resolved by 
Pryor et al. (1995), with the recognition of two additional species (see Table 1). 
Chippendale (1988) used six series names to cover the group, including E. longifolia 
Link & Otto with the grey gums (the £. pimctata group; series Punctatae herein). 
We now regard the E. longifolia group as sectionally distinct, and recognise five series 
within the section Transversaria as here circumscribed (Table 1). Brooker (2000) 
segregated the Western Australian species E. diversicolor into a separate section based 
largely on positioning of valves in fruit, and coined the sectional name Latoangulatae 
for tire remaining taxa included here in Transversaria.
