Plant like Howeara Lava Burst

[dbarron]

I recently reacquired (or thought I did) Howeara Lava Burst 'Puanami' and have rather promptly almost killed it.
Years ago, I had a much more miniature and succulent relative. It took everything and did not experience the terrible creased and faded leaves that seem to be the fate of these plants in my care. I do well with more pseudobulby (if that's a word) oncidiums and dendrobiums (latoura and biggibum types mostly). These I'm killing...not all that slowly. House humidity is about 40% in winter (low I know), but I've also tried to group them in the shower with an entire windowsill of plants behind a plastic curtain...and they no likely that either.
I now realize I didn't have this cross, it's just very similar (though larger and thinner leaved) to the plant I had.

The original plant (lost with several interstate moves) was so forgiving and yet produced the myriads of tiny flowers that Howeara does have. I originally acquired it probably 20 years ago from EOM. Does anyone have a suggestion for what I had? I'd love to reacquire it if I knew what it was. Perhaps it was one of the parents of Lava Burst?
