Is this tree leaf evolution?

Hi everyone.Essentially the answer to Straight Tree's question is that plants have a high degree of morphological variation, especially when they are in their early stages of growth and especially in their leaves.Take Eucalypts. When young, eucalypts show such a degree of variation in leaf morphology that it can be a nightmare for a botanist to identify them without recourse to examining other more definitive parts of the plant (like the fruit for example).I think Straight Tree's example is one of a plethora of variations possible for the species - especially in its formative stages.
