Can this be a seedling of Acacia auriculiformis?

leaves (similar to any other Acacia spp.) only during the early
stages. The leaf like parts seen in adult stages are actually the
modified flattened petioles. I am not really sure why this
modification has happened, but it has something to do with the arid
conditions of the native habitat of this plant.

explained the phenomenon. these structure are called Phyllode, which
are flattened petiole in contrast with Phylloclade whcih are flattened
stem or branch. function of both the modifications are same as
explained by Max-reduction of transpiration without the loss of
photosynthetic area. on a mature tree it is hard to distinguish them
from leaves if we dont have a prior knowledge that a particular
species contain or possess phyllodes. if one feels that a plant has
similar structures then holding it against the sun would show parallel
venation to a great extent which is absent in a dicot plant. even just
viewing it as such without holding it against sun would show somewhat
parallel venation. reason being that petioles dont have a venation
pattern of leaf and its vascular structure just 'placed' in whole of
structure without much of branching into a flattened space as it
matures as a phyllode.
