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 T's;eru 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 Limonia 
pumila 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 aurec foliis, floribus albis ; Parencoruttee Mala- 
barorum (Mant. 57.), justly observing, that it had more affinity to the Prunus 
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 Mal Na- 
regam. The latter, however, has a strong resemblance to Herman's Limones 
pumili, Zeylanici, sylvestres, Dehighaha zeylonensis, (Thes. Zeyl. 143. t. 65. f. 1.), 
which Linnzeus left among the plante barbare annihilate (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 Linnzus, who for his Schinus foliis pinnatis, rachi 
membranaceo-articulato, spicis axillaribus solitariis (Fl. Zeyl. 175.). afterwards 
called Limonia acidissima, quotes the Tsjerou Katou Naregam, Rheed. Mal. 4. 
t. 12., instead of the Tsjeru Catu Naregam, t. 14., and joins this to the Limonia 
Malus, sylvestris, Zeylanica, fructu pumilo, of the elder Burman, which is the 
J'alhedi or Jakuawa of the Ceylonese, while the plant meant by Linnzus is 
the Diwul or Giwul of these people (Thes. Zeyl. 89.), a name most absurdly 
derived by Linnzus from the Swedish diæwul (devil), because, forsooth, this
