Morphology of Flowering Plants

Solution:

Figure A represents alternate phyllotaxy-In this, one leaf is borne on the node and the leaves of the adjacent nodes roughly lie towards the opposite side.
Figure B represents opposite decussate phyllotaxy - In this, two leaves are borne on the opposite sides of a single node at right angles so that four rows of leaves are formed on the stem.
Figure C represents opposite superposed phyllotaxy In this, opposite leaves of two successive nodes lie in the same plane in superposed position.
