A Box. 



Systematic. A tree o| medium size, with pendulous branches. Bark of 

 the ordinary 'Box" character, persistent right or to the small branches. 

 Abnormal leaves pale green, nol glaucous, broadly ovate; the intramarginal 

 vein considerably distant from the margin, and with the midrib giving the leaf a 

 triplinerved appearance. Normal leaves lanceolate, ultimately narrow-lanceo- 

 late, 4 inches long by I inch broad, varying, however, in length and width; 

 the intramarginal vein is distinctly removed from the edge oi the leaf, although 

 this is less marked in the case oi narrow leaves, the venation is oblique, bul lew 

 el these secondary veins are as prominent as the intramarginal vein. The toliage 

 is drooping, and has frequently lung stalks. Buds clavate, the calyx tube greatl.3 

 exceeding the operculum in size; operculum nearly hemispherical, with a 

 small umbo; the calyx tube tapering gradually to the common point oi attach- 

 ment to the stalk. 



Fruit. Narrow, conical (hence the specific name , 

 tapering to the point of attachment of the 

 common stalk ; rim thin ; the valves, which 

 are three or four and very small, are 

 deeply sunk ; the greatest length 3 lines by 

 2 lines broad. 



Requires care so as not to confound them with I 



I I' i<h<n or perhaps E. crebra. 



Habitat. Found in the country west of the Dividing Range 

 and its >purs, forming, with E. hemiphloia and /•.. 



II oollsiana, the " Box " of the western country, • 

 New South Wales. 



REMARKS. -Since the original description appeared under the Vuthor's names (he. cil. . the species has 

 been lowered to varietal rank by Maiden, " Critical Revision " vol. ii, p. 123, under /■.'. Baueriana Schau., a species 

 founded on leaves and inflorescence only, " in plump bud and expanded flower," J.H.M. loo. cit. and oi tropical origin 

 Benth., B.l r !. iii, 214. Such material and description is of no practical value these times. As Deane and M iden 

 accurately describe this tree from materia] and known locality, it is thus very clear what Eucalyptus is meant 

 and so we prefer to retain their nomenclature for then there can be no doubf about the basis upon which the 

 botany and chemistry of this work is founded. 



ESSENTIAL OIL. Leaves and terminal branchlets for distillation were 

 obtained from Parkes, New South Wales, in July, 1900. The yield ol oil was 

 0-59 per cent. The crude oil was of an orange-brown colour, and had a pronounced 

 odour of volatile aldehydes. Pinene was present in some quantity, and there 

 was also' a lair amount oi cineol ; but phellandrene was not detected, and esters 

 only in small amount. It may be that aromadendral was present in small 

 quantity. The higher boiling portion contained the sesquiterpene. 



The crude oil had specific gravity at 15° C. =0.9057; rotation a D + 5-24°; 

 refractive index at >o° = 1-4676, and was soluble in 6 volumes 70 pei cent.
