Re5IAkk8 on Genera and Species. De Candolle divides the order into three tribes, 

 Sympiocece^ Styracece^ and Parnphiliacece. Species appertaining to the 2 first are found in India, 

 those of the last are all American. The first tribe contains only one genus, Symplocos^ but 

 it is a large one, embracing nearly 70 species, and appears too complex in its composition. 

 De Candolle groups the species under 5 sections some of which seem amply distinct to admit of 

 their being viewed as separate genera, as will be seen from the examples given in the supple- 

 mentary plate devoted to analyses of this and the following order. Linnaeus gave two genera, 

 Symplocos and Hopea^ to xny mind very distinct : unfortunately the latter was reduced and 

 united with the first and the name subsequently given to a totally distinct Indian genus. This 

 is to be regretted, for, if the Linnaean Hopea is again revived, it will cause no end of synonyms 

 between the two genera, a contingency only to be avoided by departing from the rule of priority 

 and adopting one of the other names now reduced. The genus Hopea of Linnaeus is distin- 

 guished from SymplocoSy by the deeply divided, almost polypetalous corolla, and the stamens 

 free almost to the base ; while in Symplocos the petals are united at the base into a distinct 

 tube and so, in like manner, are the three or four rows of filaments. (See figs. A. plate 151 b.) 

 It will be remarked that the figures representing vertical sections of the ovary of all the three 

 species, which I hav^e again verified, show that it Is completely adherent to the tube of the calyx, 

 and that the apparently free portion is a mere fleshy thickening of the base of the style. In 

 addition to the 8 species figured in the Icones, my herbarium contains several still unpublished 

 ones, but which I cannot venture to characterize without reference to authentic specimens or 

 figures in both of which my collection is deficient.

On this character 1 am disposed to place much reliance in tracing their affinities, and therefore 

 direct attention to it in this place. Assuming that I am correct in proposing the removal ot 

 StyTacace(B from this subclass, then Ilicinece would form the transition from the polycarpillary 

 to the dicarpiUary orders, as having assigned to it a dicarpiUary genus, thus confirming the 

 relationship/observed by niany Botanists, existing between it and Oleacece,^ by showing that, 

 exclusive of other characters, the two orders may be said to touch at that point. ^ 



The few genera of this order known to Jussieu, were united by him to the Jasmines, forming 

 the bulk of his order Jaaminece. with which they agree in their monopetalous, diandrous flowers.
