In my Official investigations of various Myrtaceous plants 
T have found it necessary to make a close examination of 
the material grouped under M, linariifolia and M. tricho- 
stachya, on behalf of oil-distillers. Messrs. Baker and 
Smith state*:— 
‘‘Hssential Oil.—The leaf oil of this species of Melaleuca (J. 
trichostachya) is of considerable commercial importance, as it is 
one of the richest in cineol content of any known essential oil.” 
A further statement, in the same paper (p. 594), reads— 
“M. linarvifolia appears to be more limited in its geographical 
distribution than M. trichostachya which extends over a wide area 
of country, as it occurs on the north-east coast of the continent 
and over the Main Divide to Cooper’s Creek, a rather unusual 
range,—from the moist coast region to the arid interior, and yet 
is constant in character throughout.” 
In view of these statements, I have deemed it necessary 
to bring under notice the following particulars of the range 
of these species, which is not strictly in accord with that 
given by Messrs. Baker and Smith. 
Melaleuca linariifolia Sm. in Trans. Linn. Soce., iii, 278 
(1797); Exot. Bot. t. 56 (1804-5); DC., Prod. iii, 214 (1828); 
Link’s Enum. ii, 273 (1822); Baker and Smith, this Journal 
XL, 65 (1906), and xLiv, 597 (1910) in part.
