600 THREE NEW SPECIES OF EUCALYPTUS, 



On account of the markings on the bark it could with equal 

 justice be called Spotted Gum as E. mac^d'Ha, but to distinguish 

 it from that species and to record its field character the name of 

 E. nuicnJosa is proposed. The two species, however, are never 

 found together in the same locality (W. Bauerlen). 



From the nature of the timber, bark, shape of buds and fruits, 

 venation of leaves, this species is placed tentatively after E. 

 vimi'KtIu, Labill. 



Its chemical constituents connect it with E. Snt.ithii, R.T.B. 



Under this species it ma}' be mentioned that two other trees 

 are known by the same vernacular as this tree, viz. : — 



(1) "Spotted Gum," at Charley's Forest and Fagan's Creek, 

 Braid wood (W.B.). 



(2) "Spotted Gum," at Ilford (K.T.B.). 



The chemical and botanical evidence points, as far as yet 

 examined, to these being distinct from the " Spotted Gum" of 

 Bungeiidore, but in the meantime they are placed here tentatively 

 as var. A. and var. B. of this species. 



Var. A. is at certain seasons the host of a Psyllid, producing 

 a beautifully figured, yellow-coloured lerp. 



Var. B., when wounded, exudes a whitish substance called by 

 the settlers "butter-milk " (G. Hari'is). 



Timber. -The timber of the Bungendore specimens closely 

 resembles that of the so-called E. Guunii, Hook., occurring on 

 the Snowy Mountains of this Colony, but is a little harder. It 

 is straight-grained, free and easy to work, seasons badly, and is 

 generally depreciated in value by the presence of gum-veins. It 

 is a poor commercial timber. The timl^ers of the varieties A and 

 B arH similar in texture, but superior in hardness to the type, 

 but nevertheless cannot l)e recommended for commercial use. 



Oil. — The crude oil is a light amber colour. The yield of oil 

 from fresh leaves gave lOG per cent., a mean of three distilla- 

 tions. The rectified oil is of a light yellowish tint, anrl in odour, 

 taste, etc., resembles rectified Eucalyptus oils of the better class.
