NOT Cycnoches Anne-Kathrin Berger

[serama]

I bought a number of small Cycnoches species and hybrid seedlings last year and this is the first one to bloom. It's still a pretty small plant, so I'm hoping for spikes that are two to three times as long on a fully grown plant. I took the pictures while the sun was setting, which has enhanced the yellow colour of the flowers, but they really are more coppery than they appear in the pictures, particularly on the back of the petals/sepals.

I'm really happy with this little fella but, as you can guess from the title, it turned out to be something different from what it was supposed to be. I hate it when that happens. It should have been Cyc. Anne-Kathrin Berger (Cyc. pentadactylon x Cyc. herrenhusamum), but the flowers are too full, lack the spots from the Cyc. pentadactylum parent or the appendages on the lip that both parents have. It's more similar to Cyc. Golden Showers or Cyc. Kevin Clarke, except that my flowers have some dark spotting in the centre, which means that they can't be either of these (all the parents involved in these crosses are white/green or yellow and lack purple pigments, so can't produce spotted or dark flowers). My plant is more likely a second generation hybrid with one of these two hybrids and a another one that has some Cyc. cooperi in the background ... any help at identification is highly welcome.
