Eucalyptus siderophloia, Benth. 
The Broad-leaved Ironbark. 
(Family MYRTACE^E.) 
Botanical description. —Genus, Eucalyptus. (See Part II, p. 33.) 
Botanical description.— Species, E. siderophloia, Benth. in B.F1. iii, 220 
(1866), where it is described as follows : — 
A tall tree, with a hard, persistent, rough and furrowed bark (F. Mueller and others). 
Leaves ovate-lanceolate or lanceolate, much acuminate, straight or more frequently falcate, 
about 3 to 6 inches long, often rather thick, with numerous fine diverging veins, the intra¬ 
marginal one close to the edge. 
Peduncles axillary, or in terminal corymbose panicles, more or less angular, each with about 
6 to 12 flowers, on distinct angular pedicels. 
Calyx-tube shortly turbinate, about 2 lines diameter. 
Operculum conical or acuminate, rather longer than the calyx-tube in the ordinary form. 
Stamens 2 to 3 lines long, all perfect, inflected in the bud; anthers very small and nearly 
globular, the cells very short, opening at first in oblong slits, extending at length to the 
base or sometimes almost confluent. 
Ovary convex or conical in the centre. 
Fruit globular-truncate or obovoid, 3 to 4 lines diameter, not at all or scarcely contracted at 
the orifice, the rim slightly prominent, the capsule not much or sometimes scarcely sunk, the 
valves often protruding. 
A “ coarse ” species, that is to say, having coarse fruits (as compared with 
the other Ironbarks, paniculata and crehra ) and coarsely furrowed hark. Altogether 
a very sturdy tree, reminding one, in this respect, of the British Oak. 
There is a glaucous form (var. glauca, Deane and Maiden)* which goes 
under the name of “ Blue-leaf Ironbark ” and “ Broad-leaf Ironbark ” in the Dubbo 
district. 
Botanical Name. — Eucalyptus, already explained (see Part II, p. 34); 
siderophloia, from two Greek words, sideros, iron, and phloia, hark, in reference to 
the common Australian name for such trees. 
Vernacular Names.— “ Broad-leaved Ironbark.” Perhaps this is the most 
distinctive name for this species, a characteristic by which it may he readily 
distinguished, particularly in young trees. It is often called “ Red Ironbark,’’ 
particularly from northern localities.
