90 FORMS OF FRUITS. 



Follicula (little bag follicle). Fruit ordinarily 

 membranous, opening longitudinally on the ventral 

 surface, as the larkspur, senna, &c. 



Legume or husk. Fruit which is ordinarily mem- 

 branous, elongated, and compressed in form, 

 opens longitudinally both by the ventral and 

 dorsal suture at the same time, as peas, 

 beans, &c. (fig. 118). 



Lomentum. Fruit similar to a pod or 

 legume, but contracted at different points, 

 forming partitions which result from the 

 cohesion of the two faces of the carpel, and 

 , opening by transverse sections, as in Cassia 

 ?* lia fstulajg. 119). 



24. The second division of the first class contains 

 fleshy fruits, having a thick, pulpy, and succulent 

 pericarp ; they are never dehiscent. 



It contains the two following forms : 



Drupe. Fruit fleshy, enclosing a nut internally 



(the mesocarp being fleshy and very thick, and the 



endocarp coriaceous, or bony), as the peach, the Fig. 119. 



apricot, the cherry, &c. CASSIA. 



Nut. Fruit similar to a drupe, but the mesocarp is less thick, 



and constitutes what is called a shell (as the fruit of the almond). 



Sometimes these fruits, in place of being isolated, are grouped 



together on a fleshy gymnophore so as to resemble a compound 



fruit, as in the strawberry and raspberry. 



25. The SECOND CLASS is composed of fruits that are COM- 

 POUND or SYNCARPOUS (from the Greek, sun, with, and karpos, 

 carpel or fruit) : they are formed of several carpels of the same 

 flower agglutinated together. 



26. The fruits of the first division of the second class are free, 

 not being united to the calyx or perigon through the medium of 

 the torus. The first variety contains the two following dehiscent 

 fruits : 



Silique or siliqua. Fruit dry, analogous to a legume, but 

 bilocular (from the Latin, bis, two, and loculus, partition), and 

 having the seeds attached upon the two edges of the partition in 

 each cell, as the cabbage, rose, &c. 



Capsule. Fruit dry, formed of two or more carpels united 

 together, and opening in different ways, but not bivalve, as the 



pppy-
