GUMS, RESINS, AND OTHER VEGETABLE EXUDATIONS. 1 87 



is obtained from the lumps as a yellow powder from quickly dried 

 leaves and pounding them. Soubeiran thinks the Ouliepe resin 

 is similar to Decamali from East India obtained from Gardenia 

 gummiflora, and lucida, Roxb., and there used in the hospitals as 

 a covering for wounds to protect them from insects and to absorb 

 the smell from ulcers.

Sapotace^:. 



Sideroocylon australe, Benth. and Hook., f., (Achras australis, 

 R.Br.), "Black Apple." 



The remarkable gum which exudes from our Achras australis is 

 worth investigation. I can answer for its disagreeable tenacity 

 when it gets about the hands." (Tenison- fVoods, Proc. Linn. 

 Soc. N.<S. TV., iv. 135). The juice is milky and the Order to which 

 this tree belongs yields the Gutta Percha of commerce. It would 

 not be difficult to collect a quantity of this juice for research, and 

 it should certainly be examined. 



APOCYNEiE. 



Taberncemontana macrophylla, (? Poir.). 



A gum resin from this species from New Caledonia was exhibited 

 at the Paris Exhibition, 1867. I have not heard of the occurrence 

 of a similar exudation in any Australian Apocynese. 



GOODENIACE^E. 



Leschenaultia diva/icata, F.v.M. 



For a note on a gum extracted from the roots and used by the- 

 aborigines as a cement, see Horn Expedition (62).
