Melaleuca. polyadelphia polyandria. 397 



consider it Arbor alba minor of the same author. This idea 

 was encouraged by finding- our trees agree, in most respects, 

 better with Rumph's description of the latter, than with the 

 former, and particularly because he expressly says that an 

 essential oil is obtained by distillation from the leaves of the 

 small sort ; but makes no mention of any such oil being- pro- 

 cured from the large species. These conjectures have receiv- 

 ed additional support, I may say confirmation, from the 

 Pharniacopccia above quoted. The following is a copy of 

 Dr. Powell, the translator's note, on this subject. 



" This oil was supposed to be the produce of the Melaleu- 

 ca Leucadendroji, but it appears from the specimens of the 

 Irce yielding- the true Cajuputi, sent home by Mr. Christo- 

 pher Smith, that the species is different, and referable (o 

 fab. 17 of Rmn\Auus' 8 Her bar unit A mboinense, (vol. si.J and 

 not to that author's Jlrbor alba, tab. IG. After a careful ex- 

 amination of specimens in Sir Joseph Banks', and other col- 

 lections, by Dr. Maton, and of those in the Linncean Herba- 

 rium by Dr. Smith, we are authorized to consider the tree 

 which yields the above oil, as a new species, and from the 

 names erf its medicinal product, those gentlemen have agreed 

 (o give it the appellation of Melaleuca Cqjupitli." 



As there are two figures in the 17lh table of llumphius, 

 Dr. Powell should have specified which of the two is meant, 

 but 1 take it for granted that it is the 1st.

This species was only introduced into the Botanic garden 

 in 1811, whereas M. Cajnpuli has been there since 1797-8. 

 The plants of the Ibrmer are still small, nor can they be ex- 

 pected to blossom for some few years to come, their growth is 

 scarcely so rapid as that of Cajuputi ; in habit, plants of the
