What is this? Growth looking thing on orchid but clearly part of the plant.

[Jacqmac]

Can somebody please help me identify what this is?
This is a wild orchid we have in our garden, it’s flowered 3 to 4 times over the last 20 months since we moved in, we don’t tend to it much as it’s very warm, tropical and humid here in Hong Kong, we let nature do its thing.

I recently noticed that it had this extension from a spike/stems, it is rather thick and unlike usual spike/stems, and a flower (since dead) was attached to the end of it, but not like a regular flower on a stem. I can only describe this thing as looking like okra.

What is it? Should I just leave it be? Any info on what this is?

Thanks in advance!
