Bulb. physometrum and other obscure minis

[Fishkeeper]

I picked up a few new plants from Tarzane Group, and I can't really find much about these species online. The seller has good care info in general, and the outline they gave for these sounds like pretty generic mini bulbo care.

Thing is, I've just gotten my order in, and one of these looks way weirder than I thought. I got B. nasica "Orange", B. planibulbe, B. nipondhii, B. physometrum, and a Pleurothallis cuspidata that I hope won't just up and die in a warmer terrarium. I had to give that one a try, it's precious, but I'm kinda expecting to have to rescue it.

Anyway. B. nasica and nipondhii are pretty generic-looking, as mini bulbos go. B. planibulbe is a more sprawling one, but still not that strange. B. physometrum, though? This thing's weird-looking. For those who have no idea what I'm talking about, it's this plant.



See that flattened bulb up at the top? That's a side view. They all look like that, like flattened pumpkins. The leaves lay flat, and I see that some of the bulbs have two leaves.

So, does this thing need anything other than the usual care for mini bulbos? I figure I'll keep it lightly moist, bright shade, high humidity, intermediate-warmish. It just looks so strange, I keep expecting it to want something else.

And does anyone know, will the bulbs that only have one leaf apiece grow another leaf, or do they sprout two leaves right from the start if they'll have two?
How do I tell if this one is dehydrated? Do the bulbs get more squashed-looking when they dry out, wrinkle up, or both?
