It seems like a combination of:

* Plant: referring to the biological kingdom of plants.

* Panologist: This is a made-up word. It might be a playful or imaginative attempt to combine "panorama" (a wide view) and "ologist" (a specialist).

It's possible someone invented this word to describe someone who studies plants in a broad and comprehensive way, focusing on their diverse forms, functions, and interactions within ecosystems. However, it's not a recognized term in scientific or botanical communities.

If you're looking for a related term, consider:

* Botanist: A scientist who studies plants.

* Plant Ecologist: A scientist who studies the interactions between plants and their environment.

* Phytochemist: A scientist who studies the chemistry of plants.
