GARCINIA AFFORDING GAMBOGE IN SIAM. 329 



tionable. We therefore transmitted specimens of the Singapore 1864-. 

 tree to Mr. Thwaites in Ceylon, requesting to have his judg- 

 ment as to the probable correctness of referring them to G. 

 Morella^ Desrouss., a plant with which he was perfectly familiar. 

 Mr. Thwaites, whose opinion upon other grounds we regard as 

 deserving much consideration, replied that, although the Singa- 

 pore Garcinia looked a little different from the Ceylon G. Mo- 

 rella, there could be but little doubt that it was only a form or 

 local variety of that species. If the correctness of this view be 

 admitted, it will be convenient to designate the Singapore, or 

 rather Siam, gamboge-tree, GARCINIA MORELLA, Desrouss., var. 



pedicellate, and to define it thus : Moreila.

The Garcinia elliptica of Wallich appears to Professor Oliver 

 and myself to offer no characters sufficient to distinguish it 

 specifically from G. Morella a conclusion substantially arrived 

 at by Dr. Graham nearly thirty years ago, and I have therefore 

 added it to the previously admitted synonyms of that plant. 



The curious structure of the anther in some Garcinice induced 

 Dr. Graham to propose for certain species a new genus, upon 

 which he conferred the name of Hebradendron, which, though Hebradendron. 

 abandoned by subsequent botanists, is made the title of a section 

 of the genus by Drs. Planchon and Triana. The examination 

 of the Singapore Garcinia has given occasion to Professor Oliver 

 to investigate anew the peculiarities of the circumscissile anther 

 of Graham's Hebradendron : the result of this investigation 

 will be best conveyed in the words of a memorandum with
