what is this growth?

[somewhere that’s green]

About a year ago I received a single brassia rex back bulb.

A new pseudobulb developed from the base and while it didn’t flower I watched the growth develop fully. The only noticeable damage the plant experienced was a nutrient root burn. After this I’ve been using a more dilute fertilizer and flushing the medium occasionally with distilled water.

Here’s where I’m a little confused: my brassia grew two new large pseudobulbs during it’s second growth phase. This set is different in that atop of the pseudobulbs are round 1” “mini-bulbs” (for lack of better language) with their own set of leaves. There are no signs of roots and after a couple months they haven’t grown any larger.

From what I’ve gathered online a damaged back bulb can develop a new bulb from the top. Is that what these are and if so should I look for root growth to propagate?

I haven’t seen this orchid flower yet but from what I’ve read they appear at the base of the pseudobulb.

Can anyone help guide me by sharing what’s going on with my brassia?
