to both sutures. The word pod is used in common language 

 for both these species of pericarp. Plants which produce the 

 legume are called leguminous. The greater number of these 

 plants are in the 16th class, Diadelphia. The tamarind is a 

 legume filled with pulp, in which the seeds are lodged.* 



4th. FOLLICLE, is a one-valved pericarp, which opens longi- 

 tudinally on one side, having its seed loose within it, that is, not 

 bound to the suture. We have examples of this in the dog's 

 bane (Apocynum), which is a double follicle, and in the milk 

 weed ( Asdepias).^ 



5th. DRUPE, a stone fruit, is a kind of pericarp which has no 

 valve, and contains a nut or stone, within which there is a ker- 

 nel. The Drupe is mostly a moist succulent fruit ; as in the 

 plum, the cherry, and the peach. The nut or stone, in the 

 drupe, is a kind of woody cup commonly containing a single 

 kernel, called the Nucleus ; this hard shell, thus enveloping the 

 kernel, is called the Putamen ; it may be seen in the stone of a 

 cherry or peach. J 



6th. NUT, is a seed covered with a shell, resembling the cap- 

 sule in some respects and the drupe in others ; as the walnut, 

 chesnut, &c. 



7th. POME, is a pulpy pericarp without valves, but contain- 

 ing a'rnembranous capsule, with a number of cells, which con- 

 tain the seeds. This species of pericarp has no external open- 

 ing or valve. The apple, pear, quince, the gourd, the cucum- 

 ber, and the melon, furnish us with examples of this kind of 

 pericarp. With respect to form, the Pome is oblong, ovate, 

 globular, &c. the form of fruits being much varied by climate 

 and soil. You know that apples are not uniform in their size 

 or figure. With respect to the number of cells also, the apple 

 is variable. 



8th. BERRY, is a succulent pulpy pericarp, without valves, 

 and containing naked seeds, or seeds with no other covering 

 than the pulp which surrounds it; the seeds in the berry are 

 sometimes dispersed promiscuously through the pulpy substance, 

 but are more generally placed upon receptacles within the 

 pulp. A compound berry consists of several single berries, 

 each containing a seed, united together ; as in the raspberry. 

 Each of the separate parts is called an 'Acinus, or grain. The 

 orange and lemon are berries with a thick coat. There are 

 some kinds of berries, usually so called, that seem scarce enti-
