 the footftalk is narrower than the top. 



4. An oval or elliptick leaf, is one which is 

 longer than it is broad, and whofe upper and 

 lower parts have the fame fegment of a circle, 

 fee (vr, ±. •* 



An oblong leaf {pbhnguni) is one whofe 

 length is more than twice the breadth, and 

 the two points are narrower than the fegment - 

 of a circle, fee fig. 5. 



A wedge- fl>aped leaf [cuneiforme) is one 

 that is fhaped like a wedge j the length is 

 much greater than the breadth, and is nar-'* 

 rowed from the top to the bafe, fee fig. 45. 



The angles of a leaf {anguli) are the pro- 

 minent parts which projedl from the border of 

 an entire leaf. 



An angle is different from a finus, as it 

 is the projecting part of a leaf, fee fig. 20. 

 e^ a, e^ whereas the finus is the part which 

 is diminiflied, fee fi.g. 20. a, c, b, fo the angle 

 exifts in the leaf, and the finus is without the 

 leaf. We muft not confound the fides with 

 the angle, as is frequently done. The angle 

 in a leaf is confidered horizontally, fig. 20. a^b^c^ 

 and the fide of a leaf in a perpendicular view, 

 fee fig. 58. ^, b, c.
