alternate phyllotaxy, a single leaf arises from the node. This type
of phyllotaxy is seen in sunflower, mustard, china rose. In opposite
phyllotaxy, two leaves arise from the node in opposite directions. It
is seen in guava, Calotropis. In spiral phyllotaxy, the leaves
are arranged in spiral fashion along the axis. In whorled phyllotaxy
more than two leaves arise from the node. It is seen in Alstonia.
It also shows simple reticulate venation. Thus,
the correct answer is 'Alstonia.'
