206 Dr. Francis HauivroN's Commentary 
Rheede: the leaves in Burman are emarginate, those of Rheede are rounded; 
Burman says, “ Petioli (pedunculi secundum Linnzeum) 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 Calaba of the West Indies described by Plumier, 
which, from the place of its growth, I suspect is neither the one nor the 
other. 
Linn:eus, in the Flora Zeylanica (202.), justly thought the Domba, or Doba, 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 (Thes. Zeyl. 170.), he adopted Burman's 
erroneous synonyma for the Tsjerou Ponna, calling it the Inophyllum flore 
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 flore 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 Linnzeus 
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 (FV. Ind. 120.). 
In treating of the Punna, I have already mentioned that M. Lamarck 
removed the Calaba of Jacquin and the Inophyllum flore 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 Ca/aba, 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 with folia obovata is the T'sjerou Ponna. 
In Willdenow the C. Calaba of Linnzeus is continued (Sp. Pl. ii. 1160.), 
comprehending the Tsjerou Ponna of Malabar, the Hin Kina of Ceylon, and
