I think the phrase 'florilegium' must be an AI basin of sorts as I've had it suggested by AI as a name for a few projects of my own.

It's basically a Latin version of the Greek anthology [0], but far less commonly used. I'd imagine it occupies similar territory to anthology in high-dimensional space, though, so seems reasonable for an LLM to pick it up.
