LESSON 9.] 



LOBED OK DIVIDED LEAVES. 



63 



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

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

 pahnately-veined leaves (146). 



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

 from which the main veins arise, the incisions (or simises) 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, ^oZmoie^- veined 

 leaves are palmately lobed (Fig. 122), pahnaJtely cleft (Fig. 123), 

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

 times, instead of palmately, we say digitatdy 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- 

 lohed; Fig. 123, a, palmately three-cleft; Fig. 124, Si. palmately three- 

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