Promenaea citrata - riddle

[kavanaru]

I was given a Promenaea citrata x Limelight (also found as Promenaea Limelight x citrata in the web) for my coming birthday. Curious as I am, I started looking for pictures in the web, in order to have an idea of what the flowers look like. GORGEOUS! However, I went further and try to check for the parent. I could find Promenaea Limelight, but no Promenaea citrata.

Is this a general ortographic mistake you find everywhere for this hybrid or does Promenaea citrata really exist, but hidden somewhere?

The most similar thing I have found is Promenaea citrina, currently accepted as Promenaea xanthina, and therefore the hybrid I've got should be called Promenaea Meadow Gold.

Does anyone here knows the correct answers to this "riddle"?
