Cycad revoluta chimera

[GeneAZ]

Let's see if others feel this use of "chimera" is appropriate. 

I have three C. Revolutas with apparent variegation.   However, one plant seems to be much different as it gets some size and stability in its coloration.

 

This plant consistently produces creamy yellow-ish leaves only on one half of the plant.  They emerge that way and don't change color as they harden off over the month. 

Sometimes one or two leaves will be half creamy on their whole length including the rachis all the way to the point of insertion into the caudex.  But these half cream leaves only occur on the left or right boundary of the distribution of the coloring.

This has led me to believe that the color phenomenon is on the meristem itself, or the caudex.  I want to call this a chimera trait, but it's hard to feel confident.

My other two plants grow new leaves green, then over the month they develop intense yellow marbling/variegation in a Polaroid style.

What is a botanical chimera and what is the form of coloration on my plant?

That's a weird variegation. May be good for breeding other generations for other types of variegation.
