Ch. XIV.] LINNXUS’ CLASSIFICATION OF PERICARPS. 89 
Fig. 61. 359. Fig. 61, a, represents a silique, 
the fruit of the white mustard ; this is 
rostrate, terminating like a bird’s beak ; 
b, represents a globular seed ; c, the same 
magnified ; d, shews the seed dividing 
and the embryo making its appearance, 
360. Silicle (stlicula, a little pod,) 
is distinguished by being shorter than 
the proper silique ; it is almost round, as 
@intheShepherd’s purse. This difference, 
_22% in the form of the Silique and Silicle, is 
7, 7 the foundation of the distinction of the 
@ orders in the class Tetradynamia. 
361. 3d. Lecumn, 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- 
delphia.,
