even the allusions to them in Botanical literature appear to 

 be but few. 



The Black Mapau (P. tenuifoliumj and White Mapau 

 fP. evge-nioides) yield a gum-resin, but not in quantity to 

 make it valuable. (Rep. N.Z. Exh. 1865 J. 



The resinous exudation afforded by the bark of P. 

 eugenioides was formerly used by the Maoris to perfume 

 oil ; the leaves and flowers are bruised and mixed with fat to 

 anoint their bodies. (Kirk, Forest Flora of N.Z.) 



Pittosporum floribundum, W. et A., of Western India, 

 closely allied to if not identical with P. nndulatum, yields 

 " an aromatic yellow resin or oleo-resin having- very tenacious 

 properties." ( Pharmacographica indica.) 



The above passages obviously refer to resins or gum-resins. 

 The following two species are, it will be observed, stated to 

 yield gums. 



Gums. 



A. Pittosporum phillyraoides, D. C, (Syn. P. acacioides, 

 A. Cunn.,) "Native AVillow," &c., an interior species. 

 Found in all the Colonies except Tasmania. 



This small tree is stated to yield a soluble gum. See ihe 

 following : — 



(1.) " In transparency and solubility it (Acacia gum) is 

 surpassed by the gum of Pittospornrn acacioides 

 and other Pittosporums. Mueller ( Technologist, 

 ii., 120 ; adapted from Official Catalogue, Vic- 

 torian Exhibition, 1861. J 

 (2.) " This tree yields a gum somewhat similar to gum 

 arable." 'MweWer ( Cat. Timbers, Technological 

 Museum, Melbourne.) 

 This species is also probably referred to in the following 

 passage : — " The gums exuded by the wattles and a Pitto- 

 sporum were also used as food." (Aboriginals of Victoria, 

 Brough Smyth, I., 209.^ 



B. Pittosporum bicolor. Hook. This tree is said to yield 

 a pale useful gum. (Mueller in Cat. Timbers in Tech. 

 Museum, Melbourne. J 



Anticipating a little, I may observe that all the Australian 

 Pittosporum exudations which I have met with are gum- 

 resins, and gum-resins of an interesting type. I have not 

 had the good fortune to meet with true gum on a Pittosporum, 

 and I should like very much to see such a substance from
