GROUP IV. E. NITENS. E. MACARTHURI. 
Both species are represented by scattered specimens in New Zealand, and planters 
are warned against the risk of cultivating the almost useless E. elaeophora. Seed 
of E. goniocalyoc should be obtained under competent direction from best trees at 
high altitudes in south-western Gippsland, Victoria. With such seed experiments 
should be made in both Islands, in the North up to 1,000ft. to 2,000ft.; in the 
South up to 500ft. above sea level. Where the species has failed to endure 
moderate frosts in New Zealand there is reason to suspect that it has been 
propagated from seed collected at a low altitude, and consequently from a strain 
weak in resistance to cold. 
The specific name goniocalycc is a compound of the Greek gonia corner or 
quoin and calyoc, and was appropriately suggested by the angular shape of the 
immature seed-cup. 
E. NITENS Maiden. 
This eucalypt is found in the same habitat as E. goniocalyoc and was until 
recently regarded as a variety of that species. The tree at its optimum is very tall 
and very large in girth. Dead bark non-fibrous, deciduous from branches and 
stem, except for a few feet near the ground where it sometimes persists; newly 
exposed living bark smooth and shining. Leaves in juvenile stage sessile, broad; 
on adult tree stalked, of same green on the two surfaces, generally long and 
occasionally exceeding 1 foot in length. Umbel with flowers up to seven; bud as 
a whole angular and curved; anthers as in E. goniocalyoc. Bipe seed-cup Min. 
to 3/16in. in depth and width, contracted towards both pedicel and orifice, open 
valves slightly protruding or just below rim. Mature wood pale, straight in 
grain, tough, durability not yet tested. E. nitens ranks as a giant in its native 
home and should be given competent trial on our North Island uplands. The 
Forest Service of Victoria will be able to obtain seed from certified specimens of 
large size and good form. The specific name nitens means shining, and is 
appropriate as applied to living bark, foliage, and fruit of this tree. 
50. E. MACARTHURI Deane and Maiden. 
NATURAL HABITAT, DESCRIPTION, AND USES. 
This species has its native home in south-eastern New South Wales. It 
there flourishes on moist areas along the banks of sti earns at altitudes from 
2.000ft. to 2,500ft. In an open situation the tree develops a widely spreading 
top with drooping foliage; in a dense stand it early sheds all side branches and 
develops a tall straight bole. Dead bark persistent on stem and huge branches, 
sub-fibrous, brittle, ultimately very thick and deeply furrowed. Leaves in juvenile 
stage sessile, opposite in pairs, equal-sided, broad at base, acute towards apex. 
Adult tree leaves stalked, rather narrow, falcate, and of same green on the two 
surfaces. Both forms of leaf may sometimes be seen on the same tree, with 
iuvenile leaves and fruit on the same twig. Umbel normally 7-flowered, with 
all parts delicately formed; stalk %in., stalklets Min.; lid of hud low-domed with 
minute central point; anthers with nearly parallel openings. Ripe seed-cup about 
Min. in lateral diameter, 3-celled, points of open valves slightly above rim.
