34 THE SEED-VESSEL. 



are fixed alternately to each seam. Some botanists di- 

 vide pods into two sets, one called silique and the other 

 silicle. 



The silirjut is that species of pod (F. 65) which is usually longer 

 than it is broad, having two valves, or covers, and separated by a 

 linear receptacle, the seeds alternately fixed to both sutures or seam, 

 as in the common stock and wall-flower. The siliclt- is that kind of 

 pod (F. 61) which is generally broader than it is long, having two 

 valves, and the seeds alternately fixed to both seams, as in honesty, - 

 and shepherd's-purse. 



29. The legume is likewise a seed-vessel of two valves, 

 but in which the seeds are attached to one seam only. 



Familiar specimens of the legume maybe selected, from most of 

 the plants arranged under the diade]phiaci;>ss,as the pea, &c. (F.66.) 



30. The drupe is that sort of seed-vessel, which is either 

 of a pulpy nature, containing, within, a single hard or 

 bony nut; or those having only a dry and hard shell. 



The cherry, peach, plnm, apricot, and all stone frnits, are examples 

 of one kind of drape (F.59) ; and the almond, walnnt, cocoa-nut, fil- 

 bert (F.69),and hazel (F.68), of the other. 



31. The pome is a seed-vessel of a peculiar fleshy na- 

 ture, and instead of containing a nut, like the drupe, it 

 encloses a capsule with several seeds. 



The husky part in the centre of a pear or apple, which is called the 

 heart or core, is a membranous capsule of five cells, in which are 

 contained the seeds or pips. The pulp surrounding this capsule 

 constitutes the species of seed-vessel denominated a pome. (F. 60.) 



32. The berry is that kind of seed-vessel, which is of 

 a soft and pulpy nature, containing one or more seeds,
