APPENDIX. No. V. 433 
This latter section of Oxalis* agrees also with Averrhoa Carambola} in the 
foliola when irritated, being reflected or dependent, which is likewise their 
position in the state of collapsion or sleep, in all the species of both genera. 
To the natural order formed by Oxalis and Averrhoa, the name of Oxa- 
LIDE£ may be given, in preference to that of Sensitive, under which, however, 
Batsch} was the first to propose the association of these two genera, and to 
point out their agreement in sensible qualities and irritability of leaves. 
M. de Jussieu, in a memoir recently published,§ has proposed to remove 
Oxalis from Geraniacez, to which he had formerly annexed it, and to unite it 
with Diosmez. 
It appears to me to have a much nearer affinity to Zygophyllee, || though 
it is surely less intimately connected with that order than with Averrhoa. 
I am aware that M. Correa de Serra, one of the most profound and philo- 
sophical. botanists of the present age, has considered Averrhoa as nearly related 
to Rhamnez 4] or rather to Celastrinee; from which, however, it differs in the 
number and insertion of stamina and especially in the direction of the embryo, 
with respect to the pericarpium. 
In all these characters Averrhoa agrees with Oxalis; its relation to which is 
further confirmed on considering the appendage of the seed or arillus, whose mo- 
difications in these two genera seem to correspond with those of their pericarpia. 
CHRYSOBALANE. The genera forming this order are Chrysobalanus, 
Moquilea, Grangeria, Coupea, Acioa, Licania, Hirtella, 'Thelira, and Parina- 
rium, all of which are at present referred by M. de Jussieu to Rosacee, and 
the greater part to his seventh section of that family, namely, Amygdalee. If 
Rosacez be considered as an order merely, these genera will form a separate 
section, connecting it with Leguminose. But if, as I have formerly proposed, 
both these extensive families are to be regarded as natural classes, then they 
will form an order sufficiently distinct from Amygdalez, both in fructification 
and habit, as well as in geographical distribution. 
The principal distinguishing characters in the fructification of Chrysobalanee, 
. are the style proceeding from the base of the ovarium; and the ovula (which,
