THE LEAF. 7 



incised, we describe them similarly as palmatifid, palma- 

 tipartite, palmatisected. 



When the terminal lobe of a leaf is large and round, 

 with smaller lateral lobes, the leaf is lyrate (Fig. 21). 

 When the lateral lobes have their points directed toward 

 the base of the blade, as in Fig. 22, the leaf is said to be 

 ruminate. 



APICES. When the apex of a leaf-blade is rounded, 

 as in Fig. 31, it is said to be obtuse or blunt; when ob- 

 tuse, with a broad, shallow notch in the middle, it is 

 refuse. If this notch is sharp, as in Fig. 23, it is emar- 

 ginate. 



When a blade ends abruptly, as if it had been cut

across, it is said to be truncate ; if the truncated edge is 

 ragged and irregular, as if it had been bitten off, the leaf 

 is said to be prcemorse. Fig. 24 shows an acute, or 

 sharp-pointed apex, while Fig. 27 is acuminate, or taper- 

 pointed. 



When a blade ends with a rigid point, it is cuspidate.
