generic ; but the specific name given on the plate consists of two words, Catu, 

 implying forest {sylvestris), and Tsjeru, implying that the plant has an affinity 

 with the Tsjeru delineated in the 9th plate. These names in the plate, how- 

 ever, seem to have been applied by mistake, as they are not mentioned in the 

 text, and are given, only in a reversed order, to the plant delineated in plate 

 14, which has led to several mistakes, as will be soon mentioned. 



None of the comparisons above mentioned are fortunate ; yet they seem to 

 have satisfied Herman and Commeline, who called the plant Malus Limoniu 

 pum'da sylvestris zeylanica. Plukenet was, however, inclined to class it with a 

 genus called by old botanists Coru -, and thought that it might be the same 

 with his Coru Indorum Mali aurecefoliis, Jloribus albis ; Parencoruttee Mala- 

 barorum {Mant. 57-), justly observing, that it had more affinity to the Primus 

 than to the Malus, with which Citrus was then classed. 



The elder Burman quotes this plant for his Limonia Malus, sylvestris, Zeyla- 

 nica, fructu pumilo ; but as he also quotes the Limonellus of Rumphius {Herb. 

 Amb. ii. 107. t. 29.), and the Malus Aurantia, fructu Limonis pusillo, acidissimo 

 of Sloane, there can be little doubt that he meant the species of Citrus, com- 

 monly called Lime by the English, which has no resemblance to the Mai Na- 

 regam. The latter, however, has a strong resemblance to Herman's Limones 

 pumili, Zeylanici, sylvestres, Dehighaha zeylonensis, {Tkes. Zeyl. 143. t. 65. y. 1.), 

 which Linnaeus left among the plantce barbarce annihilatce (Fl. Zeyl. 606.). 



The younger Burman quotes the Catu Tsjieru Naregam and his father's 

 Limonia Malus, sylvestris, Zeylanica, fructu pumilo, for his Limonia acidissima ; 

 but then, as the plant he meant had pinnated leaves, he quotes the 14th plate 

 of Rheede, which delineates the Tsjeru Catu Naregam, and cannot have the 

 smallest resemblance to the plant meant by the elder Burman. To this error 

 he seems to have been led by Linnaeus, who for his Schinus foliis pinnatis, racfii 

 7nembranaceo-articulato, spicis axillaribus solitariis {Fl. Zeyl. 175)- afterwards 

 called Limonia acidissima, quotes the Tsjerou Katou Naregam, Rheed. Mai. 4. 

 t. 12., instead of the Tsjeru Catu Naregam, t. J 4., and joins this to the Limonia 

 Malus, sylvestris, Zeylanica, fructu pumilo, of the elder Burman, which is the 

 IValhedi or Jakuawa of the Ceylonese, while the plant meant by Linnaius is 

 the Diwul or Giwul of these people (Thes. Zeyl. 89.), a name most absurdly 

 derived by Linnaeus from the Swedish dicewul (devil), because, forsooth, this
