TY. The paragraph says both names are cultivars.
This place claims to have pics of both, which look more different than just leaf length and compactness, showing a yellow edge. vs. a lime-colored edge, though that's not mentioned in the patent description. Hard to compare since the plants aren't in the same pic together.

This pic:
shows a plant that looks a single individual, for which the light level has changed, and now has leaves that look like both plants. I've observed the same thing on mine over the yrs.
EA only sells 'Lemon Lime,' my plant came from there, so I guess the pics are in the right place. I'm giving up trying to tell them apart, until I can find the other plant to buy. Then the difference in at least the leaf length and compactness should be obvious.
