The following notes on colours have not been standardised by reference to 

 Dauthenay, or any similar work. 



(a) E. affinis. Stuart Town (J.L.B.). " Leaves atropurpureus." 



(b) Red (bleeding heart) leaves in E. obliqua (Tasmania). (I have often seen young 



trees of this species with more or less bleeding-heart leaves, which, in trans- 

 mitted light, look very beautiful, and, in comparison with other trees associated 

 with it, very characteristic.) 



(c) " As a young tree, the marked purplish cast of its foliage gives it an ornamental 



appearance." E. Planchoniana, in Part IX, p. 291, of this work. 



(d) " A specimen of E. purpurascens Link., in Herb. Vindob., is in the opposite- 



leaved stage, and is probably E. amygdalina Labill. The underside of the 

 young foliage of this species is often purple. E. amygdalina, this work. 

 Part VI, p. 153. 



Caoutchouc. 



Young Australia has amused himself from early in the settlement of the 

 continent by pulling the young Anthocyanin-coloured shoots of Eucalyptus apart to 

 note the Cauotchouc they contain. See a popular note, " Elastic Threads in 

 Eucalyptus " in my " Forest Flora of New South Wales," i, 154. It seems to occur 

 in all members of the Corymbosee, and Angophora. As I have observed it in E. stricta, 

 it may be found in other species.
