x Preface. 



researches, however, I found a great deal that was in- 

 teresting regarding the citrus, both from scientific and 

 economic points of view. As this information was 

 scattered in different books and journals, I thought 

 that by putting it all in the Appendix it might be use- 

 ful to some future investigator of the citrus family, and 

 also to planters, &c. Moreover, in looking over the 

 " Flora of Amboyna " of Rumphius, I found, as I 

 thought, that his chapters on the citrus threw consider- 

 able light on the origin of some varieties of citrus now 

 very common in India. I made a translation of these 

 chapters for my own use. The more I looked into 

 them the more interesting I found them, and as I am 

 not aware that any translation of Rumphius's " Flora " 

 has ever been made, I thought it might be useful to in- 

 clude these chapters in the Appendix. I trust the tran- 

 slations will be found sufficiently accurate for all practical 

 purposes. I have in addition given tracings in the 

 Atlas of all the citrus delineated by Rumphius, but as 

 they are not made to any scale, it is often difficult to 

 judge of their sizes. In describing them, however, he 

 gave rough dimensions, which will help the better 

 understanding of his drawings. For the opportunity 

 of making these translations, I am indebted to Dr. G. 

 King, the director of the Royal Botanic Garden at 

 Seebpore, who very kindly lent me the copy of Rum- 

 phius in the botanical library. That copy has the 

 additional advantage of having notes at the back of 

 each plate, made by Hamilton Buchanan's own hand. 

 The Appendix contains other information, which I 

 trust may be found of some value. 



The notes, wherever found, and not otherwise stated, 

 are mine. 



I have added a Glossary to help the general reader in 

 understanding the terms which are not in common use.
