"96 ON THE OLEO-RESIN OF CANARIUM MUELLERI. 



from CaHdriuiii MueUeri, hut quite sufficient to indicate its nature, 

 and I trust that there may be placed at my disjiosal a pound or 

 two of it at the least, in order that I may complete the research. 



First of all I will give a brief resume of the exudations 

 from other ( 'anariwns. 



The (jrt'nera Ptantarnnt of Ik'ntham and Hooker (I. 821) 

 gives 16 genera and two doubtful ones, belonging to the Bur- 

 seracere, and speaks of the members of the Natural Order in 

 general as " Arbores v. frutices, ssepe elatie, balsamiflute v. olei- 

 ferte." Lindley speaks of them as " abounding in balsam or 

 resin," and this property is an important aid ni the allotment of 

 a plant to this Natural Order, particularly when the botanical 

 material is imperfect. 



CANARIUM. 



Queensland has another species, C. Aiistitdianuii}, F.v.M., 

 in Fntipii. HI., 15, transcribed Axstrnhisicuui in B. Fl. I., 377, 

 but no exudation from it is recorded. 



C. Vltiennc, A. Grray, occurs in l^'iji, and ('. Hurvei/i, Seem., 

 in Tonga, but Seemann does not record any exudation from 

 them. 



Africa.— Oliver, in the I'lont of Tnndad Africa, makes no 

 allusion to any exudation in eitlier of the two African species. 

 This is significant, as he usually takes cognizance of such 

 matters. However, I find in Moloney's Foimtri/ af West Africa, 

 the following statement referring to ( '. cilnic. Hook, f . : " Under 

 the bark are large masses of scented gam ( '? resin, J.H.]\I.), 

 used by the natives in fumigating themselves." 



India.— The Indian JJurseracea? are dealt with very fully by 

 A. W. Bennett, in the Flora of Uritisit India, and in his '* Notes 

 on Indian Burseracete " [L'/uirm. Journ. |"8j , VI., 102), he goes 

 even more fully into the matter of exudations in this Natural 

 Order. As regards Canarinm, Mr. Bemiett only refers to the 

 exudations of three species, codihihiic, strictiim and hoa/alcuse. 



C. strictwn, Eoxb., yields the well-known Black Dammar, 

 found in every museum collection, and it bears no resemblance 

 to Elemi or the product of C. Miu-llcri.
