STIPULJE. 



106. Compound leaves may be also 



Pinnate and Ternate, SfC. #c. 



107. When the edges of the lamina are not cut, the 

 leaf is called entire ; but when the reverse is the case, 

 the leaf is said to be divided. (Fig. 11.) 



108. When the petiole seems inserted into the middle 

 of the lamina, (fig. 11,) it is called peltate; when the 

 bases of two opposite leaves become united together so 

 as to form one lamina, they are said to be connate ; and 

 when many leaves are placed in a circle around the 

 same point of the stem, they are called whorled. 



109. Leaves may be glabrous or smooth, downy and 

 hairy, &c. &c. 



110. Persistent, when they continue living through 

 two or more winters. 



111. Deciduous, when they fall before new ones appear. 



112. The term caducous is given to those that fall 

 soon in the season; and the term marescent, to those 

 that wither before they leave the tree. 



Stipulte and Bractea, SfC. 



113. There are certain modifications of leaf- like ex- 

 pansions known under the terms of stipulse and bractese. 



114. Stipulte occur under two forms, the solitary and 

 connected. 



115. The first are seen in the Cinchonas, where they 



arise from the stem it- 

 self, and are destitute 

 of connection with the 

 petiole of a leaf (a). 

 The other is seen in 

 the Rose, where they 

 exist as appendages to 

 the base of a general 

 petiole (b). 



116. Stipula seem 

 to be modifications of 

 leaves ; in their solitary 

 forms being rudiments
