Juvenile growth (coppice or field seedlings to 50 cm):
stem rounded in cross-section; juvenile leaves initially opposite
but soon becoming alternate, petiolate, ovate to lanceolate or falcate,

or irregularly flexed, a few staminodes present or all stamens perfect,
anthers reniform to cordate, versatile, dorsifixed, dehiscing by confluent

dorsal surface smooth, hilum terminal.
Cultivated seedlings (measured at ca node 10): cotyledons reniform;
stems rounded in cross-section; leaves more or less sessile, opposite,
discolorous, elliptic and held horizontally for lowest ca 5 to 7 nodes,
then becoming petiolate, alternate, pendulous, ovate, 5-12 cm long,
2-4.5 cm wide, base oblique to tapering, grey-green throughout.
NOTES
Eucalyptus andrewsii (after Ernest Clayton Andrews 1870 - 1948,
Government Geologist of New South Wales from 1921 until he retired
in 1931. Whilst most of his writings were on geological and geographic
subjects, he also wrote The Geologic History of the Australian
Flowering Plants (1916), Origin of Pacific Insular Floras
(1939) and a paper on The Development and Distribution of the Natural
Order Leguminosae (1914). He had an intense interest in
Australian plant ecology and the geographical distribution of the
native flora).
A small to tall tree of blue-leaved ash group occurring from the Northern
Tablelands of New South Wales north to the vicinity of Eungella, west
of Mackay in Queensland. It has grey peppermint-type bark and is easily
recognisable in the field by the large, pendulous, alternating, broadly
falcate, bluish green juvenile leaves of the regrowth particularly
on roadsides.
There are two subspecies:
subsp. andrewsii
Has more or less hemipherical to cupular fruit and, in New South Wales,
occurs mainly on the western side of the Northern Tablelands, extending
into south-east Queensland on similar country, and further to the
north with sporadic occurrences south-west of Gladstone, west of Maryborough
and west of Mackay.
subsp. campanulata (Latin campanulatus, bell-shaped,
of the fruit).
Occurs more on the eastern side of the Northern Tablelands, New South
Wales and adjacent areas of far south-east Queensland. It has obconical
to cupular fruit reminiscent of E. sieberi, of southern
New South Wales, eastern Victoria and Tasmania. The bark of E.
sieberi is, however, black and furrowed.
Eucalyptus andrewsii belongs in Eucalyptus subgenus
Eucalyptus section Cineraceae series Psathyroxylon
having the following characters: cotyledons reniform, juvenile leaves
alternate, bluish, adult leaves with side-veins acute, single axillary
inflorescences with buds in clusters of 11 to 15, buds with single
operculum, inflexed stamens, some outer stamens without anthers (staminodes),
the remainder with reniform anthers, style usually short, ovules in
2 rows, and seeds ± pyramidal. Within series Psathyroxylon,
E. andrewsii is closely related to four other tree species,
three with rough, finely fibrous bark on the trunks; E. consideniana
from southern New South Wales and eastern Victoria; E. remota
which is endemic to Kangaroo Island, South Australia; and E.
olida which occurs on the eastern side of the Northern Tablelands
of New South Wales and can be distinguished by the unpleasant odour
of the adult leaves and the long style. The fourth rough-barked species
related to E. andrewsii is E. sieberi from southern
New South Wales, eastern Victoria and Tasmania which has hard, blackish,
furrowed, rough bark on the trunk. A fifth species in this group,
E. multicaulis , is a mallee south from the Wollemi area of
New South Wales to about Pigeon House Mountain and has little or no
rough bark. These six species form subseries Considenianae.
USES
