In No. 1 , CrucifercB, a a represents the position of the stigmata with 

 respect to the placentoe ; 6 i the two placentae ; c c the ovula ; d d the 

 double septum ; and e e the two valves. 



In No. 2, Eschscholtzia, a a represents the position of the perfect stigmata 

 with respect to the placentae ; 6 6 the sides of the pericarpium connecting 

 the placentae ; c c the ovula ; d d the position of the two abortive stigmata ; 

 e e the line of pericarpium corresponding with the two abortive stigmata. 



Now, let the valves of Cruciferae (e e, No. 1) be contracted into the space 

 of a line, and they answer exactly to the line (e e, No. 2) corresponding 

 with the abortive stigmata of Eschscholtzia— let the placentae (6 b. 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 h, No. 2). 



For these reasons, it appears to us that the theoretical definition of the 

 fruit of Cruciferae should be this ; 



formed 



stigmata 



two destitute of placentae and stigmata, but separable in the form of valves
