I think you need a better description... Almost any stem plant (aquatic or
terrestrial), when cut off, will start to grow two branches, each with the
characteristics of the original. ie. cut off a plant that has two leaves at
each node and you will get two stems with two leaves at each node. Same with
apple trees and spruce trees.
If your father is seeing something that he hasn't seen before, then you must
be describing it poorly.
a picture perhaps?
