A marked specific character is that the terminal branch- 
lets are arranged quadchotomously, and occasionally tricho- 
tomously. 
Technology.—(1) Timber. This is a very hard, close 
grained, even textured timber, of a very light colour, with 
a small dark or black ebony centre, otherwise it resembles 
*“*Hinglish Box,’’ Buxus sempervirens. Itisa much harder 
wood than any Australian described Croton. 
(2) Bark. This is the most aromatic portion of the tree, 
and ‘‘fresh specimens of wood with the bark on, when 
taken into a room, give a strong aromatic atmosphere, and 
odour approaching that of ‘chloroform,’ in fact almost 
overpowering if left in the room too long.’’—A. Paddison. 
To me it is a far more pleasant odour than chloroform. 
It is quite a distinct aroma from that of C. phebalioides. 
Mueller states, (Frag. Iv, 14) that C. phebalioides exudes 
a resin, but diligent search amongst the known trees failed 
to discover any such substance in this tree. 
In an aromatic classification of the whole genus, it might 
be placed with such exotic species as C. aromaticus, Linn., 
East Indies; C. suaveolens, Tarr., Mexico; C. birmanicus, 
Muell. Aug., Burma; three species containing an essential 
oil, out of about 450 species known for the Genus. 
(3) Leaves.—These are also aromatic, and yield an 
essential oil with a pleasant odour. Mueller, (Fragmenta, 
Iv, p. 140) records that C. stigmatosus now C. phebalioides, 
contains a pleasant aroma in its leaves, so that there are 
two species of this genus now in Australia possessing an 
essential oil in their leaves. Mr. H. G. Smith, who inves- 
tigated the oil of this species, states: The amount of leaves 
with branchlets was only 21 tbs., from which but three 
grams of oil were obtained, equal to 0°03 per cent. The 
crude oil-was of an amber colour, had a terpene odour, 
with an indefinite secondary one. Cineol was not present.
