OEWNARY LEAVES.

Entire, when their general outline is completely filled out, so that the 

 margin is an even line, without teeth or notches. 



Serrate, or Saw-toothed, when the margin only is cut iuto sharp teeth, 

 like those of a saw, and pointing forwards : as in Fig. 142. 



Bentttte, or Toothed, 

 when such teeth point /i/V ,.-_/\V/\ -/^-v 



outwards, instead of 

 forwards ; as in Fig. 

 143. 



Crenate, or Scal- 

 loped, when the teeth 

 are broad and round- ] 

 ed ; as in Pig. 144. \ 



Repand, Undulate, 

 or Wavy, when the 

 margin of the leaf 

 forms a wavy line, 

 bending slightly in- 

 wards and outwards in succession; as in Fig. 145. 



Sinuate, when the margin is more strongly sinuous or turned inwards 

 and outwards ; as in Fig. 146. 



Incised, Cut, or Jagged, when the margin is cut into sharp, deep, and 

 irregular teeth or incisions ; as in Fig. 147. 



Lobed, when deeply cut. Then the pieces are in a general way called 

 Lobes. The number of the lobes is briefly expressed by the phrase two- 

 lobed, three-lobed, five-lobed, many-lobed, etc., as the case may be. 



140. When tlie depth and character of the lobing needs to be more par- 

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



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

 about half-way between the margin and the centre of the blade, if so far, 

 and are more or less rounded ; as in the leaves of the Post-Oak, Fig. 148, 

 and the Hepatioa, Fig. 152. 



Gleft, when the incisions extend half way down or more, and especially 

 when they are sharp; as in Fig. 149, 153. And the phrases two-cl0, or, 

 in the Latin form, bifid, three-cleft or trifid, four-cleft or quadrifid, fi,ve- 

 cleft or quinquefid, etc., or many-cleft, in the Latin form, multifid, — express 

 the number of the Segments, 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 Fig. 150, 154. And 

 the terms two-parted, three-parted, etc., express the number of sucli 

 divisions. 



Divided, when the incisions extend quite to the midrib, as in the lower 

 part of Fig. 151, or to the leaf-stalk, as in Fig. 155 ; wjiich really makes the 



Fro. 142-147. Kinds of margin of leaves.
