Botanical Name. — Eucalyptus, already explained (see Part II, p. 34) ; 
macrorrliyncha, from two Greek words, makros , long, and rhynchos, a beak, in 
allusion to the long, beaked flower-bud. 
Vernacular Names. — It is usually known as Stringybark” merely, but by 
comparison with E. euyenioidcs as “ lied Stringybark.” According to Howitt, it is 
known as “ Mountain Stringybark” in Gippsland, a name to which in this State the 
other Stringy barks have also some claim. It is the common Stringybark of the 
north-eastern districts of Victoria, and appears to be quite absent from the coast 
districts of New South Wales. 
Leaves. —The oil of the leaves has been investigated by Baker and Smith.* * * § 
They obtained by distillation a yield of 0'28-0'31 per cent, of oil. The oil is 
reddish-brown, has the sp. gr. 0 92L-0 - 927 at 22°, and begins to boil at 172°. It 
contains a trace of phellandrene, cineol, and crystallized eudesmol.t 
I first drew attention J to the presence of a yellow colouriug matter in the 
leaves during progress of my research on the tannin content of various leaves, but it 
was reserved for Mr. H. G. Smith to make a full chemical investigation of this 
substance, which he called “ Myrticolorin.”§ 
During the last drought, Mr. E. B. Guthrie made an analysis of the leaves 
with respect to their fodder value, with the following result ( Agric . Gaz. N.S.JE., 
Oct., 1899) :— 
Water. 
Ash. 
Fibre. 
Ether extract 
(oil, &c.). 
Albuminoids. 
Carbo¬ 
hydrates. 
Nutrient 
value. 
Albuminoid

Fruits. —The fruit has usually a sharp rim, but in northern and western 
New South Wales specimens this is not always the case, the rim being often rounded 
and even domed. 
Timber. —Hard, and mostly tinged with a deeper red-brownish coloration, 
but occurs also paler coloured; it is durable, and easily fissile into fence-rails, shingles, 
and palings, and is very useful for all purposes for which rough split timber is 
required above ground ; it is also sawn into weatherboards and scantlings, and 
furnishes a fair fuel. The specific gravity of the seasoned wood is about 1 020 or 
63|- lb. to the cubic foot (Mueller). A sample from the Monaro, New South Wales, 
is an excellent furniture wood, being light, strong, and close-grained, and capable of 
a good polish. It is, however, chiefly used for fencing and wheelwrights’ work in 
southern New South Wales.
