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.

Quoting Wikipedia:

> The word is from the Latin flos (flower) and legere (to gather): literally a gathering of flowers, or collection of fine extracts from the body of a larger work.

There's obviously the scholarly allusion and the literal floral allusion here, so even if it is AI generated it's right on the money in this case :) You would struggle to find a more apt name.
