359. Fig. 61, a, represents a silique. 

 the fruit of the white mustard ; this is 

 rostrate, terminating like a bird's beak ; 

 6, represents a globular seed ; c. the same 

 magnified ; d, shews the seed dividing 

 and the embryo making Us appearance. 



360. Silicic (silicula, a little pod,) 

 is distinguished by being shorter than 

 the proper silique ; it is almost round, as 

 in the Shepherd's purse. This difference, 

 in the form of the Silique and Silicle, is 

 the foundation of the distinction of the 

 orders in the class Tetradynamia. 



361. 3d. LEGUME, is a pericarp of two valves, with the 

 seeds attached only to one suture or seam ; as the pea. 



362. In this circumstance it differs from the Silique, which 

 has its seeds affixed to both Sutures. The word pod is used in 

 common language for both these species of pericarp. 



363. Plants which produce legumes, are called leguminous 

 The greater number of these plants are in the 16th class, Dia-
