THE EDGE. 



[BOOK in. 



2. Of Division. 



A. With respect to the Margin. 

 3 4 



1. Entire (integer). Properly speaking, this means having no kind of marginal 



division ; but sometimes it has been used to indicate not pinnatifid, and also 

 nearly destitute of marginal division. 



2. Quite entire (integerrimus) ; perfectly free from division of the margin. 



3. Crenated (crenatus) ; having convex teeth. When these teeth are themselves 



crenated, we say bicrenate. 



4. Sawed (serratus) ; having sharp straight-edged teeth pointing to the apex. 



When these teeth are themselves serrate, we say biserrate, or duplicate- 

 serrate. 



5. Toothed (dentatus) ; having sharp teeth with concave edges. When these 

 teeth are themselves toothed, we say duplicato-dentate, or doubly toothed, 

 but not Hdentate, which means two-toothed. 



6. Gnawed (erosus) ; having the margin irregularly toothed, as if bitten off. 



7. Curled (crispus) ; having the margin excessively irregularly divided and 



twisted ; as in many varieties of the Garden Endive, Mentha crispa. 



8. Repand (repandus, ^smuolatus)', having an uneven slightly sinuous margin; 

 as the leaf of Solanum nigrum. 



9. Angular (angulatus, angulosus) ; having several salient angles on the 

 margin ; as the leaf of Datura Stramonium. 



10. Sinuate (sinuatus) ; having the margin uneven, alternately with deep 

 concavities and convexities ; as the leaf of Quercus Robur. 



B. With respect to Incision. 



1. Torn (lacerus); irregularly divided by deep incisions. 



2. Cut (incism) ; regularly divided by deep incisions. 



3. Slashed (laciniatu#) ; divided by deep, taper-pointed, cut incisions. 



4. Squarrose-slashed (squarroso-laciniatus) ; slashed with minor divisions at 

 right angles with the others.
