206 Dr. Francis Hamilton's Commentary 



Rheede: the leaves in Burman are emarginate, those of Rheede are rounded; 

 Burman says, "Petioli (pedunculi secundum Linnaeuin) ex alis foliorum oriuntur 

 communiter solitarii trifidi ;" but the flowers in the Tsjerou Ponna are evidently 

 disposed in racemes, and are much larger than in the Hin Kina of Burman. 

 Burman has increased the difficulty by annexing, as the same with the Tsjerou 

 Ponna and Hin Kina, the Calaha of the West Indies described by Plumier, 

 which, from the place of its growth, I suspect is neither the one nor the 

 other. 



Linnaeus, in the Flora Zeylanica (202.), justly thought the Domba, or Doha, of 

 the Ceylonese to be the Ponna of Malabar, while the Kina he considered as the 

 Tsjerou Ponna, taking no notice of the Hin Kina, because probably he thought 

 that both Kina major and minor formed only one species. Although he thus 

 corrected one error of Burman, who did not consider the Domba as belonging 

 to the same genus with the Ponna {T/ies. Zeyl. 1/0.), he adopted Burman's 

 erroneous synonyma for the Tsjerou Ponna, calling it the Inophyllum jiare 

 quadrifido of Burman, and the Calaba folio Citri splendente of Plumier, thus 

 including in one species three plants, the Kina or Tsjerou Ponna, the Hin 

 Kina or Inophyllum Jlore quadrifido, and the Calaba. His specific character, 

 " Calophyllum foliis ovatis obtusis," is applicable to neither the plant of Rheede 

 nor that of Burman, the former having " folia obovata," and the latter " folia 

 emarginata," and was, therefore, probably taken from the American plant, 

 which may have been that in M. Cliffort's collection, from whence Linnaeus 

 first derived his knowledge of this Calophyllum ; and on this account in the 

 Species Plantarum he retained the American name Calaba, written Caleba by 

 the younger Burman {Fl. Lid. 120.). 



In treating of the Punna, I have already mentioned that M. Lamarck 

 removed the Calaba of Jacquin and the Inophyllum Jlore quadrifido of Bur- 

 man to his C. Inophyllum, and he thus leaves the Tsjerou Ponna to form a 

 species by itself, in which I think he is perfectly right ; but then he strangely 

 gives it the American name Calaba, and he defines it as having " folia ovata," 

 while the Inophyllum according to him has "folia obovata ;" but in the figures of 

 Rheede the only plant represented withyb//a obovata is the Tsjerou Ponna. 



In Willdenow the C. Calaba of Linnaeus is continued {Sp. PI. ii. 1160.), 

 comprehending the Tsjerou Ponna of Malabar, the Hin Kina of Ceylon, and
