GROUP IV. E. MACARTHURI. E. MAIDENI. 
The mature wood is pale with very slight tinge of red, coarse in grain, liable 
to form wide radial cracks in drying; durable up to 20 years in contact with the 
ground. Some trees are freely fissile, others tough to split. For the genera 
purposes of a farm the timber of this tree is very valuable. 
CULTIVATION IN NEW ZEALAND. 
As might be expected from its natural habitat, E. Macarthuri can endure a 
good many degrees of frost. It is very easily propagated eithei by sowing in situ 
or by transplanting from the seed bed. It has found a particularly congenial 
home on the pumiceous lands in the Hamilton-Cambridge-Putaruru aiea, and theie 
has grown rapidly to a very large size. Experiments to ascertain its useful range 
at higher altitudes and farther south are in progress. It is essentially an inland 
tree and must not in any case be planted within reach of severe saline winds. Seed 
obtained from the best acclimatized trees can be supplied by the Forest Service. 
The specific name Macarthuri was given in honour of Sir William Macarthur, 
who did much to promote knowledge and appreciation of the eucalypts in the 
earlier years of research. 
51. E. MAIDENI F. von Mueller. 
NATURAL HABITAT, DESCRIPTION, AND USES. 
This species has its natural distribution on the uplands of north-eastern 
Victoria and south-eastern New South Wales at altitudes of 1,000ft. to 2,000ft. 
It is one of the least known of the eucalypts, and yet possibly for our country 
one of the most important. At its optimum the tree reaches heights up to and 
over 150ft., and diameters up to 3ft. and even 4ft., with a long shaft-like bole free 
from side branches. Dead bark non-fibrous; deciduous from branches and stem, 
leaving bluish-white surface of living bark. Leaves in juvenile stage broad and 
sessile or on very short stalks; those of saplings and adult trees stalked, narrower, 
and up to 8in. long; lateral veins wide apart and forming oblique angles with 
midrib. Umbel with several flowers; stalk thick, 96 in. to /sin. long, stalklets /6in. 
less or more; lid of bud low with blunt projection in centre, and bud as a whole 
sometimes slightly warty; anthers with longitudinal and nearly parallel openings. 
Ripe seed-cup 34in. or less in lateral diameter, plain or with two slight ridges at 
sides, rim sloping to orifice, open valves slightly protruding and claw-like. 
Mature wood pale yellow, hard, interlocked in grain, and reputed to be both 
strong and very durable. Small but quite mature poles are said to serve well and 
last long when used for carrying electric wires. 
CULTIVATION IN NEW ZEALAND. 
E. Maideni somewhat resembles E. globulus, but it is clearly distinct from 
that species, and probably more resistant to cold. A few scattered specimens 
have been noted by the writer in this country, but all in situations where it was 
evident that they had come from seeds accidentally mixed with other species. No 
time should be lost in obtaining seed from competently certified and approved
