As to division of blade, compare oak, maple, pas¬ 
sion vine, water melon, tongue grass, and learn 
the meaning of lobed, cleft, parted and divided. 
As to variation, a number of leaves should be 
used, representing those with petioles, without 
petioles ; with stipules, without stipules; with bud 
in axil, as common, simple leaf of almost any sort; 
without bud in axil, as observed in any leaflet of 
compound leaf; colors, red, yellow, green, varie¬ 
gated, etc.; venation, parallel veined, netted veined. 
Draw several kinds of simple leaves, showing 
venation, petiole, etc. Draw several compound 
leaves, such as horse chestnut, walnut, locust, 
acacia, strawberry. 
Lead the children to see that the bud of a com¬ 
pound leaf is found in the axil of the entire leaf¬ 
stalk and not in the axils of the leaflets. Most 
simple leaves have buds in the axil. The syca¬ 
more and a few others may seem like exceptions 
to the rule, as the bud in such trees is always 
under the cup of the leaf-stalk. 
Under variation, may also be discussed bud 
scales, as in hickory or lilac, modified for protec¬ 
tion of the green leaves within; the tendrils as in 
pea vines ; spines as in barbery ; bulb scales as in 
onion. This might be carried much further, but 
the foregoing is thought to be sufficient for third
