harder in age; said to stand well in damp ground; some affirm its great 
strength and durability; seeds winged. 
E. eximia is the Mountain Bloodwood; Bentham thought this species more 
nearly allied to EZ. maculata or Spotted Gum than to Bloodwood; flowers large, 
corymbose; the operculum or lid is double, the seed-vessel is urn-shaped, 
nearly an inch long; top of capsule deeply sunk. 
E. stricta is a shrubby species; fine linear leaves; forms thick brushes; it is 
the E. microphylla.of Cunningham. 
E. dives* and E. piperita are two of the Peppermints; the first has small, 
and often opposite leaves; the latter very large, like a Stringy Bark, but not 
so thick, nor are they so oblique at the base; flower-buds smaller; lid more 
hemispherical and sharper at the point, whilst the seed-vessel is more globose; 
but they vary from Mountain Ash (£. radiata) in bark and habit; 5 to 15 feet 
diameter; 200 feet of clear shaft, etc. 
E. melliodora, the Red Flowering or Black Iron Bark; flowers ornamental; 
delicious honey-like odor, as the name indicates; 60 feet; timber in quality 
variable. 
E. panniculata, and E. cerebra (one species), are mere varieties of the White 
Tron Bark, one of the most valuable trees; specific gravity, 1.016; the breaking 
weight of a transverse strain of a beam four feet between bearings 17% square, 
4,519 lbs.; best of all the Iron Barks; a smooth, uniform outer bark; hard, 
tough, inlocked strong wood; highly esteemed by coach-makers and wheel- 
wrights for poles, shafts, ete., of carriages, spokes of wheels; also largely for 
piles and railway sleepers; 150 feet high by 16 feet diameter; both of these 
are united into one species. 
_ E. siderophloia is the Red or Large-leaved Iron Bark, formerly described as 
E. resinifera; this yields the brown gum or Botany Bay Kino (inspissated 
juice). The wood though not so tough as the preceding, is considered one 
of the strongest and most durable of timbers. There are two varieties; both 
vary from 80 to 120 feet, distinguished by the bark, which is darker color than 
the £. panniculata or White Iron Bark, and the leaves are more uniformly 
larger. 
E. melanophioia is the Silver-leaved or Broad-leaved Iron Bark; a taller tree 
than the other Iron Barks, and readily known by its stemless or sessile 
opposite leaves, which are glaucous or mealy white. 
E. obliqua, E. capitella and E. macrorhyncha—Hon. Wm. Woolls, F. L. 8. (from 
whom we collate), considers them all as forms of the Stringy Bark, only 
varying with climate, soil, elevation or proximity to the sea, etc.; rises to 100 
*It is possible this may be the Shingle tree (?) of a previous note.
