Ctenanthe golden mosaic can you tell differences?

[youngalistairyoung@yahoo.]

I have just received 2x ctenanthe marantifolia in the post on unwrapping they look exactly the same as lubbersiana?. There are other names/ varieties that seem to fall under the umbrella of "golden mosaic" plant but being any different remains to be seen.

I think the difference is how big they get and probably something in the flowers.
