680 SOME NEW SPECIES OP EUCALYPTUS, 



It is quite distinct in specific characters from the two stringy- 

 barks described in this paper, viz., E. nigra and E. umbra. 



Timber. — Pale-coloured, very hard, close-grained, heavy. In 

 transverse and compression tests, it stands higher than that of 

 any of the other Stringybarks above enumerated. It is evidently 

 an excellent timber, and is strongly recommended for forest 

 conservation. 



Oil. — The yield of oil from this species averages about -9 per 

 cent. It consists very largely of lsevopinene. A small quantity 

 of eucalyptol is present in the oil at some time of the year, and 

 a small quantity of phellandrene at others. This terpene alters 

 much, occurring in small quantities in many Eucalyptus oils at 

 certain seasons of the year, whilst at other times it is absent. 

 The specific gravity of the crude oil was -894 at 15° C. 



The specific rotation of the crude oil = [a] j_>— 239; no phellan- 

 drene was detected in the January oils. 



No less than 86 per cent, of the oil distilled below 170° C. 

 The hevo-rotation of this oil is due to the lsevopinene present, 

 The odour of the oil after saponification of the small quantity of 

 ester present is exactly that of oil of turpentine (H. G. Smith). 



E. OVALIFOLIA, Sp.nOV. 



" Red Box." 



(Plate xlvi., figs. 6a, 66.) 



A medium-sized tree with a smooth bark, decorticating at the 

 base of trunk, producing a roughish appearance. 



Leaves small, of light yellowish colour, sometimes glaucous, 

 oval or ovate, shortly acuminate, mostly 2 inches long and f 

 inch wide, rarely 3 inches long; venation faintly marked, lateral 

 veins distant, oblique, spreading, the marginal vein removed 

 from the edge, producing at the base of the leaf a trinervate 

 appearance. Petiole slender, under 1 inch long. 



Flowers in axillary or terminal panicles, 6-8 in the head. Calyx 

 under 2 lines long, 1 line in diameter, tapering into a slender 

 pedicel. Operculum hemispherical, depressed, very shortly acu-
