sible of this error, and classed it with the Corn, of which, as I have said in 

 treating of the Mai Naregam, tlie prototype is probably the Feronia Elephan- 

 tum of modern botanists. 



In commenting on the Mai Naregam, I have already mentioned the error 

 into which the elder Burman fell by quoting this plant for the mdhedi or 

 Jahuawa of the Ceylonese, which, from the synonyma of Rumphius and Sloane, 

 seems to be rather the small-fruited Citrus, called Lime by the English. Lin- 

 nseus seems to have been aware of this, and therefore joined the Tsjerou Katou 

 Naregam with the Diivul or Giwul, although by an error, probably typogra- 

 phical, he quotes plate 12 in place of 14. On this subject I have in this com- 

 mentary made already some remarks. The Tsjerou Katu Naregam, or Diwul, 

 Linnseus in the Flora Zeylanica (17ft-) considered as a species of Schinm, thus 

 placing it in the order of Terebinthacece ; but from his synonyma we must 

 reject those of Burman and Sloane, which belong to the small-fruited Citrus. 



The younger Burman having become sensible that the Tsjerou Katou Nare- 

 •ram could not be a Schinus, the fruit of which is a drupa, formed a new genus, 

 which he called Limonia, and in this he included this plant and another, since 

 called Triphasia, and thus returned to the old system of placing it among the 

 Aurantia;, which shows how nearly the Aurantice and Terebinthacece are allied. 

 The Tsjerou Katou Naregam may therefore be most justly considered as the 

 real prototype of the genus Limonia, and is perhaps still the only species pro- 

 perly belonging to it, several, at least, of those since annexed by Linnaeus and 

 others having both a very different character and appearance. Burman, in- 

 deed, added as synonymous the Anisifolium or Boa Balangan of Rumphius 

 {Herb. Amb. ii. 133. t. 43.), which, however, that excellent botanist merely 

 says has the same habit (foliatura) with the Tsjerou Katou Naregam ; and the 

 elder Burman, in his explanation of the plate (43.), points out essential dif- 

 ferences. We may infer, from Linnaeus quoting the plant of Rheede alone for 

 his plant, that it was this he meant ; and as Burman's Limonia acidissima is 

 the Schinus of Linnaeus, it cannot be the Anisifolium, although Willdenow 

 continues to join them {Sp. PI. ii. 572.). Yet, that even he means the Katou 

 Naregam alone, may be inferred from his describing the fruit " Bacca trilocu- 

 laris, seminibus solitariis." The Anisifolium is now considered as forming a 

 distinct genus, and is called Feronia Elephant urn {Enc. MM. Suppl. ii. 630. ;
