Eucalyptus Caleyi Maiden. 
Caley's Ironbark. 
(Family MYRTACE^E.) 
Botanical description. Genus, Eucalyptus. (See Part II, p. 33.) 
Botanical description. Species, E. Caleyi Maiden in Proc. Linn. Soc. N.S. W., 
xxx, 512 (1905). 
A tall Ironbark tree, often glaucous, and finally becoming glabrous, but remaining dull -coloured. 
Vernacular Names. Called " Broad-leaved Ironbark " at Howell in comparison with the local 
"Narrow-leaved Ironbark," which is E. sideroxylon, and which is rare in the immediate 
district. Also called " Silver-leaved Ironbark," but not to be confused with E. melanophloia, 
which is not found in the neighbourhood, but which is exceedingly abundant near Bingara, 
Inverell, <fec. 
Bark very deeply furrowed and hard, with much less kino in grains throughout the bark than 
E. sideroxylon, and therefore not a true " Fat-cake Ironbark " like that species. 
Timber deep red in colour, locally esteemed, and apparently a timber of good quality. 
Juvenile leaves nearly orbicular, 3 inches in diameter being the usual dimensions. The leaves 
are symmetrical, and taper rather abruptly into a petiole of about | inch. Texture 
thick and coriaceous, dull and even glaucous. Midrib rather prominent, and the 
intramarginal vein at a considerable distance from the edge. The secondary veins (of 
which the intramarginal rein is one) numerous, usually about inch apart, roughly 
parallel, but converging and finally becoming nearly parallel to the midrib. 
Mature leaves broadly lanceolar, up to a breadth of 2 inches, and a length twice as great and 
rather more. Nearly symmetrical, blunt-pointed, tapering at the base into a petiole of about 
an inch. Coriaceous and rather thick, equally dull on both sides ; often glaucous. Intra- 
marginal vein at a considerable distance from the edge. The secondary veins rather 
prominent and wide apart, and disposed at about an angle of 45 degrees to the midrib. 
Buds. Operculum conical, and of less diameter than the calyx, which tapers much more than 
does the operculum. The buds often glaucous. 
Flowers axillary, becoming terminal by reduction of the upper leaves. Up to 7 in the head, 
the common peduncle rather slender, and about \ inch in length, each flower on a distinct 
pedicel. Anthers almost quadrangular in shape, opening in pores nearly terminal, which 
are a little wider in the direction of the broad portion of the anther. Filaments often 
tinged red and minutely glandular. In full flower in August. 
Fruits pear-shaped, slender, tapering into a distinct pedicel. Diameter, say \ inch, with a length 
about twice as great. Dark brown and glossy when fully ripe. They have a marked dark 
coloured thin rim, such us is common in E. sideroxyhin and E. mclliodora. Valves well 
sunk, usually half-way down the capsule. 
Botanical Name. Eucalyptus, already explained (sec Part II, p. 34) ; 
Caleyi, in honour of George Caley, Banks' Botanical Collector in New South Wales 
(1800-1810), and whose shrewd observations in regard to another Ironbark have 
been referred to at p. 94, Vol. 5, of this work.
