DESCRIPTIVE BOTANY. 



PART 1. 



and, strange as the idea may seem, it has been conjectured, 

 that the providing of such animal manure for the plant, 

 is one object which these singular appendages were in- 

 tended to accomplish. There is, certainly, a striking 

 analogy between this result, and the still less equivocal 

 object effected by the fly-traps of the Dionaea, to which 

 we shall have occasion to allude when speaking of the 

 irritability of plants. 



(c.) In the Cephalotua follicularis, the pitchers (r) 

 are about two inches long, and are seated round die 

 base of the flower-stalk, intermixed with the radical 

 leaves. Though so much smaller, they are perhaps 

 still more curious and striking than those of the Ne- 

 penthes. 



(81.) Vernation of Leaves. Before the leaves ex- 

 pand, they are compactly folded together in the leaf-bud ; 



and the various modes in which this takes place, is called 

 their " vernation." The folds or plaits either lie in a 

 longitudinal direction, parallel to the midrib ; or they 

 are transverse, so as to bring the apex and base towards 

 each other. Different terms are applied to the various 

 modes of vernation, some of which, however, are seldom 

 employed in descriptive botany. The appearances re- 

 presented in the annexed cut (fiy. 72.) are among the
