LESSON 9.] 



LOBED OR DIVIDED LEAVES. 



63 



upper row of figures consists of feaiher^eined, or, in Latin form, 

 pinnately-veined leaves (145) ; tlie 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 sinuses) being 

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

 leaves are pinnately lohed (Fig. 118), pinnately cleft, or pinnatifid 

 (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, joafoja^eiJy-veined 

 -leaves are palmately lohed (Fig. 122), palmately cleft (Fig. 123), 

 palmately parted (Fig. 124), ov 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 ihree- 

 hbed ; Fig. 123, a. palmately three-cleft ; Fig. 124, a. palmately three- 

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



F'G. 118-121. Pinnately lobed, cleft, parted, and divided leaves. 



PIG. 122 - 125. Palmately or digitately lobod, cleft, parted, and divided leaves.
