as in Amygdaleze, are two in number,) as well as the embryo being erect. The 
greater part of Chrysobalanez: have their flowers more or less irrecular; the 
irregularity consisting i 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, 
Chrysobalanus and Parinarium.* One species of the former is hardly dis- 
tinguishable from Chrysohalanus 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 Adanson} 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 
found by Adanson at Senegal, and has moreover remarked that their ovar1um 
coheres with the tube of the calyx. In that species most common at Sierra 
Leone, and which is probably one of those examined by M. de Jussieu, the 
ovarium itself is certainly free, its pedicellus, however, as in the greater part 
of the genera of this order and several of Casalpinege, firmly cohermg with the 
calyx, may account for the statement referred to. I am not, indeed, acquainted 
with any instance among Dicotyledonous plants of cohesion between a simple 
ovarium, which I consider that of Chrysobalanez to be, and the tube of the 
calyx. 
The complete septum between the two ovula of Parinarium, existing before 
fecundation, is a peculiar structure in a simple ovarium; though in some 
degree analogous to the moveable dessepiment of Banksia and Dryandra, and 
to the-complete, but less regular, division of the cavity that takes place after 
fecundation in some species of Persoonia.|| 
MELASTOMACE. Four plants only of this order occur in the 
collection. 
The first is a species of T'ristemma, very nearly related to 7". hirtum of M. 
de Beauvois.4]
