Bulbophyllum mounts spare space.
 

I bought two Bulbos at an auction recently that have heaps of spare room on them and I'm wondering if it would be bad to mount some of my other smaller bulbos
[in particular maximum, lasiochilum, laxiflorum, rothschildianum] on the spare space in terms of saying showing the plant and judging?

Would they be considered more than one plant -even if only the one bulbo was flowering and therefore not accepted?

The mounts are about 30cm by 40cm and 90% spare room:

the one on the left is B. sumatranum and the one on the right is B. echinolabium.

Those Bulbos need to be repositioned. Once they start sprawling, all that "spare space" is going to be taken up.

I think the person who sold you the Bulbos did you a favor. Now you don't have to buy a larger mount to accomodate them when they get larger. All you have to do is reposition them towards the middle and watch 'em grow!
