LEAVES 21 



2. Broadest near the base. Deltoid, ^Abroad and tri- 

 angular. Ovate, rffffi evenly curved, ^j$ with a broad, 

 rounded base. ^^^ Heart-shaped or cordate, ^j^l similar 

 to ovate, but with a notch at the base. ^^ Lan- 

 ceolate, /-^ shaped like the head of a lance. Awl- 

 shaped, J*=^ ^g^g. shaped like the shoemaker's curved 

 awl. Scale- *^^ ^ shaped, ^ short, rounded, and ap- 

 pressed to the stem. The jfe? Arbor-vitaB has both 

 awl-shaped and scale- ? shaped leaves. 



3. Broadest near the apex. Obovate, /7g\ same as ovate, 

 but with the stem at the narrow end. J/E^S Obcordate, 



a reversed heart-shape. Oblanceolate, 



versed lanceolate. Wedge-shaped or cuneate, 



having a somewhat square end and straight sides like a 



wedge. 



These words are often united to form compound ones 

 when the form of the leaf is somewhat intermediate. The 

 term which most nearly suits the general form is placed 

 at the end; thus lance-ovate indicates a leaf between 

 lanceolate and ovate, but nearer ovate than lanceolate; 

 while ovate-lanceolate indicates one nearer lanceolate. 



BASES. Oftentimes leaves are of some general form, 

 but have a peculiar base, one that would not be expected 

 from the statement of shape. An ovate leaf which should 

 have a rounded base might have a tapering one ; it would 

 then be described as ovate with a tapering 6ase."-^c 

 A lanceolate leaf should naturally have a tapering base, 

 but might have an abrupt one. /zjfe Many leaves, no 

 matter what their general form ^~^>> may be, have 

 more or less notched bases ; such bases are called cor- 

 date,_(3^ deeply or slightly, as the case may be; and 

 if the <& lobes at base are elongated, auriculate. 

 If the basal lobes project outward, the term halberd- 

 shaped A is used. Any form of leaf may 

 have <^\H a base more or less oblique.
