Do not see a justification for a taxonomist claiming a piece of the action. Why would merely naming a species give a taxonomist claim to any future use? Can you elaborate?

Taxonomists often don't see financial benefit from their discoveries, even when those discoveries lead to commercially valuable plants, because the link between initial taxonomic work and commercialization is often indirect and complex. Several factors contribute to this disconnect, including the lack of clear legal frameworks for recognizing and rewarding taxonomic contributions, limited opportunities for taxonomists to participate in the commercialization process, and the general underfunding of taxonomic research.
