376 R. T. BAKER AND HENRY G. SMITH. 



Material of this species was also received from Port 

 Macquarie, in this State, and distilled November 1910. In 

 general appearance and characters it resembled the oil from 

 the Gosford sample, and was even more viscid. The 

 specific gravity at 15° C. = 0*9552, which is higher than 

 that of the sample from Gosford. The refractive index at 

 24° C. = 1*4923. The saponification number of ester + 

 free acid = 8*1. The rotation was not sharp, but it was 

 between two and three degrees to the right.

Plate XVII. 

 Fig. 1. A cross section through the centre of a complete leaf, 

 showing the general disposition of the parenchymatous tissue, 

 oil glands and vascular bundles. x 110 



Fig. 2. A cross section through half a leaf, towards the upper 

 portion. x 110. 



Plate XVIII. 

 Fig. 3. A transverse section through little more than half a leaf. 

 The midrib on the extreme right is surrounded by sclerenchy- 

 matous fibres shown black in the plate; a smaller bundle is on 

 the extreme left towards the edge of the leaf. Other rudi- 

 mentary bundles are seen in the median line but not sur- 

 rounded by fibres as in the case of the other two. A few 

 oil glands are seen. x 1 40.
