I am not sure what that might be.
Looks like a large cluster of cells like a bunch of new leaves or buds. But they do not look like buds.
What orchid where??

Can you post a photo of the rest of the plant?

I got it wrong it's not an orchid it's a Lilly. This is the whole plant

Oops! Didn't attach. Try again.

Lilies make bulblets and multiply that way. However those are so tiny and close packed, they look like a blob of undifferentiated tissue culture cells that are starting to differentiate into leaves. Many plants are propagated by tissue culture now, so a recent purchase might still have a bit of the undifferentiated tissue culture cells remaining that are capable of making new plants. Maybe...

It looks like it is trying to make a bunch of bulblets there, sometimes my lilies do that too and they are not tissue cultured. If you grow thousands of them for years all kinds of weird and strange things happen. this year many stems are making bulblets, stem from divisions that don't do that - normally.

I find when those bulblets happen, it is more often stress. Around the country there is a lot of environmental factors that could come in to play. I would cover it with some soil and see what comes of it next year. They also seem to get some energy at that stage from the mother bulb.
