KINDS AND FORMS OF LEAVES. 51 
‘ 
the upper row are called pinnately lobed, cleft, parted, or divided, as the case may 
be, and those of the lower row palmately lobed, cleft, &c. The number of the. lobes 
or pieces may also be expressed in the same phrase. Thus, Hepatica has a pal- 
mately three-lobed leaf (Fig. 121); the Red Maple a palmately five-cleft leaf (Fig. 
84), and so on. 
141. In this way almost everything about the shape and veining of a leaf may 
be told in very few words. How useful this is, will be seen when we come to study 
plants to find out their names by the descriptions. : 
142. All these terms apply as well to the lobes or parts of a leaf, when they are 
themselves toothed, or lobed, or cleft, &c. And they also apply to the parts of the 
flower, and to any flat body like a leaf. So that the language of Botany, which the 
student has to learn, does not require so very many technical words as is commonly 
supposed. 
143. Compound Leaves (121) are those which have the blade cut up into two or 
more separate smaller blades. The separate blades or pieces of a compound leaf 
are called Leaflets. The leaflets are generally jornted with the main footstalk, just 
as that is jointed : 
with the stem, and { 
when the leaf dies 
the leaflets fall off 
separately. i 
144. There are 
two kinds of com- 
pound leaves, the 
pinnate and the 
palmate. 
145. Pinnate 
leaves have their 
leaflets arranged 
along the sides of : 
the main foots talk, Odd-pinnate. Pinnate with a tendrit. Abruptly pinnate. 
as in Fig. 128, 129, 130. 
_146. Palmate (also called Digitate) leaves bear their leaflets all at the very end) 
of the footstalk; as in Fig. 181. hi 
147. There are several varieties of pinnate leaves, The principal sorts are: —.,
