In No. 1, Crucifere, aa represents the position of the stigmata with 
respect to the placente; 6b the two placente; cc the oyula; dd the 
double septum; and ¢ e the two valves. 
In No. 2, Eschscholtzia, a a represents the position of the perfect stigmata 
with respect to the placente; 6 6 the sides of the pericarpium connecting 
the placente ; ¢c the ovula; dd the position of the two abortive stigmata ; 
e ¢ the line of pericarpium corresponding with the two abortive stigmata. 
Now, let the valves of Cruciferee (e e, No. 1) be contracted into the space 
of a line, and they answer exactly to the line (¢ e, No. 2) corresponding 
with the abortive stigmata of Eschscholtzia—let the placentze (bb, No. 1) be 
widened in proportion as the valves (e e) were contracted, and they will 
answer exactly to the placentiferous valves of Eschscholtzia (b b, No. 2). 
For these reasons, it appears to us that the theoretical definition of the 
fruit of Cruciferee should be this :—Pericarpium formed of four confluent 
pistilla, of which two are placentiferous and furnished with stigmata, and 
two destitute of placente: and stigmata, but separable in the form of valves.
