204 Dr. Francis Hamilton's Commentary 



properly the B'mtangor of Riimphius, the leaves of which are not of this form. 

 He retained, however, among the synonyma all the three plants of Plukenet, 

 which have been already mentioned. 



The younger Burman takes from the Species Plantarum the specific name 

 Inophyllum, adds to the synonyma the B'mtangor of Runiphius, and omits the 

 only one of three species of Plukenet which I think belongs to the Ponna, 

 that is, the Nux bengalensis Juglandi folio fructu orbiculari {Aim. 265.). 



M. Lamarck {Enc. Mdth. i. 553.) considers the Ponna as his Calophyllum 

 Inophyllum ; but this is not distinguished " foliis ovalibus," as Linnaeus justly 

 defines them, but "foliis obovatis." It is probable, therefore, that M. Lamarck 

 actually described the Focraha, or Fooraha, of Madagascar, which he quotes as 

 synonymous. The seeds of the Ponna indeed produce a lamp-oil ; but I never 

 heard of its producing, like tlie Fooraha, an odorous resin like the Tacamaque 

 of Bourbon, the qualities attributed to which are totally different from those 

 attributed by Rheede to the gum of the Punna. M. Lamarck also joins to the 

 Punna the American Calaba described by Jacquin. Whether or not this is 

 the Red-wood of Barbadoes, considered by Plukenet as the same with the 

 Punna, I cannot say ; but I suspect it is on no better authority that the Ca- 

 laba and Punna are made one species. Linnaeus, it must be observed, thought 

 them different. Whether or not it is the Calaba or the Fooraha that M. La- 

 marck represents in his figure (///. Gen. t. 459.) I cannot say ; but it certainly 

 is not the Punna. Its leaves, like those of the Bintangor maritima, which 

 M. Lamarck places among the synonyma of his Calophyllum Inophyllum, are 

 emarginate ; but the flowers are totally dissimilar to those of both the Punna 

 and Bintangor, at least as represented in the figure with leaves (a.), which, if 

 not taken from that work, strongly resembles the figure of the Inophyllum Jlore 

 quadr'ifido of Burman {Thes. Zeyl. t. 60.). This, indeed, is quoted by Linnaeus 

 as representing the C. Calaba ; but it certainly is totally different from the 

 Ponna. Perhaps M. Lamarck intended that his figure should represent both 

 his varieties, that marked a, belonging to one variety, and those marked 

 h, c, d, e,f, g, h, belonging to the other variety ; but no hint of this is given 

 in the Supplement. 



Willdenow makes little change on the synonyma {Sp. PI. ii. 1159.) as they 

 stood in the Flora Indica of Burman, only he omits that of the elder Burman
