198 R. T. BAKER AND H. G. SMITH. 



texture, almost membraneous, rarely 4" long, mostly under 

 3" and about J" wide, ovate, straight, now and again falcate. 

 Venation fine, varying in number from 3 to 5 prominent 

 ones, the flowering rachis having a white silky pubescence,, 

 flowers distant. 



This, evidently, then is the true M. minor of Smith and 

 at any rate is the species from which cajuput oil is obtained, 

 for the analysis of this specimen of oil agrees with the 

 published analyses of cajuput oil, and differs from those of 

 all Australian Tea Trees going under the name of M» 

 leucadendron. It must also be stated that Treub's 

 specimens differ botanically from any Australian material 

 seen by us. 



IV. Remarks on the Species Synonymised under M. 

 leucadendron, Linn., by various Authors. 



M. leucadendron, Linn. 



This species, as far as our knowledge goes, we regard a& 



extra-Australian. 



M. minor, Sm. (M. cajuputi, Roxb.) 

 This species also for the same reason should be regarded 

 as extra-Australian. 



M. Ounninghami, Schau. 

 This species is placed by Bentham in Fl. Austr., iii, 143, 

 (loc. cit.) under M. leucadendron, Linn., but the original 

 locality and description (Walp. Rep. ii, 927) show conclu- 

 sively that it is M. viridifiora, Solander. 



From this it would appear that Schauer had not access 

 to the British Museum drawings and descriptions. 

 M. saligna, Schau. 



This is described by Schauer in Walp. Rep., ii, 927, and 

 the locality is the same as M. Cunninghami — Endeavour 

 River. It is therefore tropical, and from a drawing of the 

 original by Dr. Daydon Jackson, London Linnean Society
