682 SOME NEW SPECIES OF EUCALYPTUS, 



Mudgee Flora, so that it must have escaped their observations, 

 as it occurs at Hargrave, mid-way between Mudgee and 

 Wellington. 



Timber. — When growing on poor ironstone ridges the tree 

 becomes rather stunted and the stem has a tendency to barrel, so 

 that it yields only small specimens of timber. It is red-coloured, 

 hard, close and straight-grained, and very durable in the ground. 

 It is suitable for all kinds of heavy work. 



Oil. — The yield of oil from this species is *27 per cent. It con- 

 tains much phellandrene and but a minute quantity of eucalyptol 

 at time of distillation. It is not, however, a commercial oil. It 

 is distinctly different from E. polyanthema, Schau., of the south, 

 which gives a commercial oil rich in eucalyptol. 



The specific gravity of the crude oil at 15° C. is -9058. The 

 specific rotation of crude oil [a] jj = - 9-93°. 



There is very little difference in the constituents of this oil and 

 that of E. Fletcheri, Baker, the " Lignum-vita? " or Black Box at 

 St. Mary's, as they both contain the same constituents in 

 practically the same amount (H. G. Smith). 



E. Fletcheri, sp.nov. 



" Lignum-vitae," "Box." 



(Plate xlv.) 



A medium-sized tree with a box-bark on the trunk, branches 

 smooth, branchlets glaucous. 



Leaves from orbicular to ovate-acuminate in shape, sometimes 

 oblique, cuneate or rounded at the base, from 1 inch to 3 or 4 in 

 diameter, thin, not shining ; venation faintly marked, lateral 

 veins oblique, spreading ; intramarginal vein removed from the 

 edge, more pronounced at the base, giving a trinerved appearance 

 to the leaf. Oil glands very numerous ; flowers numerous in 

 axillary or terminal panicles ; peduncles short, 2-3 lines long. 



Buds about 5 lines long. Calyx conical, with scarcely any 

 pedicel. Operculum hemispherical, very shortly acuminate or 

 obtuse.
