LEAVES 21 
2. Broadest near the base. Deltoid, \ broad and tri- 
angular. Ovate, evenly curved, with a broad, 
rounded base. 7 Heart-shaped or cordate, similar 
to ovate, but with a notch at the base. Lan- 
ceolate, EZ, shaped like the head of a lance. Avwi- 
shaped, ete shaped like the shoemaker’s curved 
awl. Scale- shaped, _, Short, rounded, and ap- 
pressed to the stem. The E. Arbor-vite has both 
awl-shaped and_ scale- shaped leaves. 
3. Broadest near the apex. Obovate, same as ovate, 
but with the stem at the narrow end. Obcordate, 
a reversed heart-shape. Oblanceolate, =< > a mV) 
versed lanceolate. Wedge-shaped or cuneate, ee) 
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 base. Ke 
A lanceolate leaf should naturally have a tapering base, 
but might have an abrupt one. Ce Many leaves, no 
matter what their general form may be, have 
more or less notched bases; such bases are called cor- 
date, -. deeply or slightly, as the case may be; and 
if the lobes at base are elongated, awriculate. 
If the basal lobes project outward, the term halberd- 
shaped is used. Any form of leaf may ftw 
have 7/7 a base more or less oblique. & IZ
