Node. Node.

NODE.-The point on the stem from which leaves are given off.

INTERNODE.-The portion of the stem between two nodes.

LEAF AXIL.-The point at the upper side of the leaf where it joins the stem.

NOTE.-Children will easily find the nodes and internodes of most stems, but they should not, therefore, hurry past this exercise without tracing the successive internodes of many stems from the root upward. The teacher should also see that a clear idea is gained of the axil of a leaf.

If Figs. 116 and 117 are not intelligible to beginners, and the parts of short stems like these are distinguished with difficulty, let them be passed over, as the coming exercises are not dependent upon these discriminations. But, for those who can make them out, they will be profitable.

bud.

TERMINAL BUD.-The bud at the end of the stem.
AX'ILLARY BUD.-The bud in the axil of a leaf.
BRANCH.-A stem which grows out of an axillary

LEAF.-Petiolate, exstipulate, palmate-veined, 5lobed, broad as long; lobes rounded, entire; sinuses deep, round; petiole long, slender.

The appendages of the stem (Fig. 118) are leaves, buds, and branches. The terminal bud continues the growth of the main stem. Axillary buds give rise to branches, or secondary stems.

E

STEM leaves grow along the stem.

RADICAL leaves start close to the ground, or below its surface.

NOTE. The term radical would seem to imply that the leaves spring from roots, which is not the case, as shown in Fig. 117.
