THE LEAF 



95 



110-116. Kinds of margin of leaves: 110, 

 serrate; 111, dentate: 112, cre- 

 nate ; 113, repand ; 114, sinuate ; 

 115, incised. 



Repand, Undulate, or Waoy, when the margin of the leaf forms a 

 wavy line, bending slightly inwards and outwards in succession; as 

 in Fig. 113. 



Sinuate, when the margin is 

 more strongly sinuous or turned 

 inwards and outwards ; as in 

 Fig. 114. 



Incised, Cut, or Jagged, when 

 the margin is cut into sharp, 

 deep, and irregular teeth or in- 

 cisions ; as in Fig. 115. 



Lobed, when deeply cut. 

 Then the pieces are in a gen- 

 eral way called LouES. The 

 number of the lobes is bi'iefly 

 expressed by the phrases two- 

 lohed, three-lohed, Jive-lnhed, many-lohed, etc., as the case may be. 



When the depth and character of the lobing needs to bo more par- 

 ticularly specified, the following terms are employed, viz. : — 



Lohed, in a special sense, when the incisions do not extend deeper 

 thau about halfway between the margin and the center of the blade, 



if so far, and are 

 more or less round- 

 ed ; as in the 

 leaves of the Post 

 Oak, Fig. 110, and 

 the Hepatica, Fig. 

 120. 



Cleft, when the 

 incisions extend 

 halfway down or 

 more, and especially 

 when they are sharp; 

 as in Figs. 117, 121. 

 And the phrases 

 tioo-cleft, or, in the 

 Latin form, hifd, 

 three-cleft or trifid, 

 four-cleft or qxiadri- 

 fd, five-cleft or quin- 

 qitefid, etc., or many- 

 express the number of the segments, 



116-123. Margrins of deeply cut leaves: 116, pinnately 

 lobed; 117, pinnately cleft; lis, pinnately 

 parted; 119, pinnately divided; 120, pal- 

 mately three-lobed ; 121, palmately three- 

 cleft; 122, palmately three-parted; 123, 

 palmately three-divided, or trisected. 



cleft, in the Latin form, multijid, 

 or portions. 



Parted, when the incisions are still deeper, but yet do not quite 

 reach to the midrib or the base of the blade ; as in Figs. 118, 122. And
