MR. D. HANBURY ON A SPECIES OF GARCINIA. 489 
Ceylon ©. Morella, 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. pedicellata, and to define it thus :— 
G. Morella, Desrousseaux, in Lamarck, Encyclop. Méthod., Botan. iii, /01, pl 405. fig. 2; 
Thwaites, Enum. Plant. Zeylan. i. 49. 
G. elliptica, Wallich, Catal. no. 4869. 
G. Gutta, Wight, Illustr. of Indian Botany, i. 126, tab. 44 (exclus. synon. Linnei). 
Hebradendron cambogioides, Graham, in Hooker's Companion to Bot. Mag. ii. (1836) 193, tab. 27. 
Var. 8. pedicellata; floribus masculis pedicellatis (pedicelli ad 3 lin. longi). 
The Garcinia elliptica of Wallich appears to Professor Oliver and myself to offer no 
charaeters sufficient to distinguish it specifically from G. Morella—a conclusion sub- 
stantially 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 G'arcinic induced Dr. Graham to propose 
for certain species a new genus, upon which he conferred the name of Hebradendron, 
which, though 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 circum- 
scissile anther of Graham’s Hebradendron: the result of this investigation will be best 
conveyed in the words of a memorandum with which Professor Oliver has favoured me, 
and which is as follows :— 
“The specimens of the gamboge Garcinia from Messrs. D'Almeida have afforded me 
excellent material for the examination of the anthers of this species, which exhibit an 
unexpected and curious structure, which structure, however, is no doubt common to all 
the species of the section Hebradendron. 
** Professor Graham, in his paper upon Hebradendron, in the ‘Companion to the Botanical 
Magazine’ (ii. 193), quotes an extract from a letter which he had received from the late 
Robert Brown, in which Mr. Brown pointed out to him ‘ that approaches to this struc- 
ture [referring to the circumscissile anthers], and which serve to explain its analogy 
with the ordinary structure of the family, exist in Garcinia.’ Messrs. Planchon and 
Triana, in their excellent memoir on Guttifere, in the description of their sixth section 
of Gurcinia (§ Hebradendron), refer thus to the peculiar structure of م‎ erip 
‘antheræ peltatæ rima circulari dehiscentes, ideoque quasi circumscissæ. Mr. Brown’s 
observation as to the existence of intermediate forms, connecting the struc- 
ture of the Hebradendron-anther with that of other Garcinia, is a true one; 
but in the genus Garcinia there occur two distinct forms or types of anther, 
and he does not indicate of which form he regarded the Hebradendron-anther 
as a modification. In some Garcinie, as in G. paniculata, the anthers are 
truly peltate, the comparatively slender apex of the filament being attached 
near the middle of the back of the anther (fig. 1). In these species the ic 
anther-cells are right and left on the upper surface, and the dehiscence is longitudinal,
