LESSON 9.] 



LOBED OB DIVIDKD LEAVES. 



upper row of figures consists of feather-veined, or, in Latin form, 

 pinnately-veined leaves (145); the lower row, of radiate-veined or 

 palmately-veined leaves (146). 



159. In the upper row the incisions all point towards the midrib, 

 from which the main veins arise, the incisions (or sinvses) being 

 between the main veins. That is, being pinnately veined, such 

 leaves are pinnately lobed (Fig. 118), pinnately cleft, or pinnatijid 

 (Fig. 119), pinnately parted (Fig. 120), or pinnately divided (Fig. 

 121), according to the depth of the incisions, as just defined. 



160. In the lower row of figures, as the main veins or ribs all 

 proceed from the base of the blade or the summit of the leaf-stalk, so 

 the incisions all point in that direction. That is, palmately-veined. 

 leaves are palmately lobed (Fig. 122), palmately deft (Fig. 123), 

 palmately parted (Fig. 124), or palmately divided (Fig. 125). Some- 

 times, instead of palmately, we say digitately cleft, &c., which means 

 just the same. 



161. To be still more particular, the number of the lobes, &c. 

 may come into the phrase. Thus, Fig. 122 is a palmately three- 

 lobed ; Fig. 123, a. palmately three-cleft ; Fig. 124, & palmately three- 

 parted ; Fig. 125, a palmately three-divided, or trisected, leaf. The 



FIG. 118 - 121. Pinnately lobed, cleft, parted, and divided leaves. 



FIG. 123-135. Palmately or digitately lobed, cleft, parted, and divided leaves.
