:::::::Your assertion is not supported by the evidence. Certainly you could not argue that the Google Books hits favoring Medusagyne are the result of specialist publications. Regardless, that's a moot point. This is a way to determine what the most common name is in reliable sources. Clearly Medusagyne is preferred, so the article already is "for the reader!" For more evidence, let's look at the Google ngram, which found mentions of Medusagyne but didn't even locate "Jellyfish tree" in any capitalization at all in English language books! The evidence is overwhelming that this is the correct WP:COMMONNAME title. I won't continue this futile discussion since it's not productive; you aren't being swayed by the fact and seem to have a hard time admitting that you're wrong about this. That's fine, of course, but if you want to pursue another WP:RM that ends in failure, please do so. My only contribution to that will be to oppose with a summary of my comments above.
