|Better Farming Series 02 - The Plant: the Stem; the Buds; the Leaves (FAO - INADES, 1976, 30 p.)|
The leaves of yam are not like those of cassava.
You can recognize a plant by looking at the leaves.
Leaves are simple or compound.
· Simple leaf
The simple leaf can be entire or lobed.
Entire simple leaf
Examples: yam , millet, okra., hibiscus, maize, cocoa, teak, coffee
Lobed simple leaf
Examples: cassava, cotton
· Compound leaf
Look carefully at the drawing of a groundnut leaf. What it shows
is not four groundnut leaves. It is a single leaf.
But this leaf is made up of a midrib bearing four little leaves.
These little leaves are called leaflets.
The midrib of a compound leaf is not a stem.
So there is never a bud between the midrib and the leaflets.
