@
Hughesdarren:, apparently this is a recent change in POWO. Wikispecies cites POWO (as of 2019) for D. americana, and iNaturalist has a record for D. americana (they also follow POWO). WFO accepts D. americana, and their record is based on WCSP (another Kew resource). POWO's record for Dracaena ghiesbreghtii is messed up; it cites Tropicos as a publication, and Tropicos doesn't have any record for D. ghiesbreghtii (!!!); POWO also cites Flora Mesoamericana, but according to Tropicos the name in Flora Mesoamericana is D. americana. D. ghiesbreghtii was
described from material from Mexico, and that publication predates the publication of D. americana. So if there is a single Dracaena species from Central Americana (which doesn't seem to be disputed), D. ghiesbreghtii has priority. But it does seem like a situation where a proposal to conserve D. americana against D. ghiesbreghtii would probably be successful.

I left the following feedback for the creator/future reviewers while reviewing this article: Hi there, thanks for the article. According to POWO this species is a synonym of Dracaena ghiesbreghtii, I've reviewed it but asked for assistance from another user to get there thoughts on whether this is correct or not. Regards.
