NATURAL ORDERS. 115 



these two genera seem to correspond with those of their 

 pericarpia. 



CHRYSOBALANE^. The genera forming this order 

 are Chrysobalanas, Moquilea, Grangeria, Coupea, Acioa, 

 Licania, Hirtella, Thelira, and Parinarium, all of which 

 are at present referred by M. de Jussieu to Rosacese, and 

 the greater part to his seventh section of that family, 

 namely, Amygdalese. If Rosacese be considered as an 

 order merely, these genera will form a separate section, 

 connecting it with Legmiainosse. But if, as I have form- 

 erly proposed, both these extensive families are to be 

 regarded as natural classes, then they will form an order 

 sufficiently distinct from Amygdalese, both in fructification 

 and habit, as well as in geographical distribution. 



The principal distinguishing characters in the fructifica- 

 tion of Chrysobalanea are the style proceeding from the 

 base of the ovarium ; and the ovula (which, as in Amyg-[«4 

 dalese, are two in number) as well as the embryo being 

 erect. The greater part of Chrysobalanese have their 

 flowers more or less irregular ; the irregularity consisting 

 in the cohesion of the foot-stalk of the ovarium with one 

 side of the tube of the calyx, and a greater number, or 

 greater perfection of stamina on the same side of the 

 flower. 



Professor Smith's herbarium contains only two genera 

 of this order, namely, Chrysohalanus and Parinarium} 

 One species of the former is hardly distinguishable from 

 Ckrysobalanus Icaco of America, and is probably a very 

 common plant on the west coast of Africa ; Icaco being 

 mentioned by Isert^ as a native of Guinea, and by Adan- 

 son' in his account of Senegal. 



Of Parinarium, there is only one species from Congo, 

 which agrees, in the number and disposition of stamina, 

 with the character given of the genus. In these respects 

 M. de Jussieu* has observed a difference in the two species
