110. Internal Structure of Stems; Cellular Tissue; Wood. 111. The two classes of stems. 112. Ex- 
amples, both in herbs and trees. 118. Endogenous stem; how its wood is arranged. 114. External 
appearance and growth. 115. Exogenous stem; common wood. 116. How it increases in diameter 
year after year: Sap-wood and Heart-wood. 117. The latter dead, the former annually renewed. 118. 
External appearance and mode of growth. 
119. Leaves ; their varieties, why useful to learn. 120. Their parts: Blade, Footstalk, Stipules. 
121, Simple and Compound. 122. Structure and Veining of leaves: woody or fibrous part; cellular 
tissue or green pulp ; Epidermis or Skin. 123. Ribs. 124. Veins and Veinlets; Nerves, so called. 
125. Two kinds of veining. 126. Netted-veined or Reticulated. 127. Class of plants that have this 
kind of veining. 128. Parallel-veined or Nerved; class of plants that have this kind of veining. 
129. Both kinds of two sorts. 130. Feather-veined or Pinnately veined. 131. Radiate-veined or Pal- 
mately veined. 
182 Shapes of leaves enumerated; as to general outline. 188. Those that taper downward. 184, 
185. Intermediate shapes, how expressed. 186. Shapes depending upon the base. 187. Forms of 
apex. 138. As to margin or toothing, &c. 189. Lobing or division. 140. How this is related to the 
veining; how both the kindof lobing and the number of parts may be expressed, 141, so that a short 
phrase will describe the leaf completely. 142. All the various terms apply as well to other parts, as 
to calyx, corolla, petals, &c. 
148. Compound Leaves ; Leaflets. 144. The two kinds. 145. Pinnate leaves. 146. Palmate or 
Digitate. 147. Varieties of pinnate leaves. 148. Number of leaflets. 149. Also of palmate leaves ; 
why their leaflets are generally fewer than those of pinnate leaves. 150, Twice or thrice compound 
and decompound leaves. 
151. Leaves without distinction of blade and footstalk ; Needle-shaped ; Thread-shaped ; Awl- 
shaped; Equitant. 152. Stipules; often united with the footstalk, or with each other. : 
183. The arrangement of leaves on the stem: the three modes, viz, alternate, opposite, whorled.
