I've got these sunflower seedlings - most of which like the one in the
bottom of the picture have two cotyledons and paired leaves.

However, one, as you can see had three cotyledons and has triple leaf
sets. They're exactly like ordinary sunflower leaves - only spaced 120°
round the stem.
Is this unusual in sunflowers? I've never seen it before.
