An interesting known periclinal chimera in citrus is the 'Thompson Pink'
grapefruit. It's peel is genetically 'Marsh' white grapefruit, and its
apomictic seeds always produce 'Marsh' trees. But the middle layer, which
produces the edible pulp, makes the pink pigment (lycopene) that 'Marsh'
does not. 'Burgundy' grapefruit, a very much darker-colored variety, is
also likely a periclinal chimera of the same type.
