as in Champa. 



A LEGUME is a fol- 

 licle which dehisces by 

 both the sutures, so 

 that the pericarpdivides 

 into two halvesorvalves 

 as they are called, as in 

 Pea (see fig. 91), moog, 

 arhahar, shone, and 

 kal-kasonda. In some 

 legumes transverse 



spurious dissepiments 

 are formed between the 

 seeds, so that the cell- 

 cavity is not continu- 

 ous, but divided into one-seeded compartments, and 

 the fruit when ripe does not dehisce at the sutures, 

 but breaks up transversely into one-seeded 

 segments. Such a legume is distinguished 

 as a LOMENTUM, as in the sensitive plant or 

 lajwabati (fig. 138), shola, mat-kalai or 

 chiner-badam, and gila {Entdda). In a 

 legume or lomentum the pericarp is often 

 constricted and compressed transversely be- 

 tween the seeds. Legumes are popularly 

 known as pods ; in fact, all long fruits are 

 so called. 



A siLiQUA (fig. 139) is a syncarpous fruit 



with two carpels, originally one-celled, but 



rendered two-celled by the growth of a 



spurious dissepiment called replum. It is 



a pod which dehisces into two valves, from the bottom 



towards the top, leaving the replum standing in the
