hey mate...
here is your answer...
It is of three types, alternate, opposite, and whorled phyllotaxy. In alternate phyllotaxy, a single leaf arises from the node of a branch. This type of phyllotaxy is observed in the sunflower, mustard, and peepal. Plants with opposite phyllotaxy have two leaves arising from the node in opposite directions. It is found in guava and jamunplants. Plants with whorled phyllotaxy have three or more leaves arising from the node. It is found in Alstonia.
