Taxon changes for change in hybrid status - not needed?

[silversea_starsong]

I’d still call this subjective as some authors see a timeline where this symbol no longer becomes necessary. For instance, a species with a well-documented hybrid origin that has shown to keep distinct for a long period of time (years, decades?). In those cases I’ve seen authors opt to drop the × symbol because even though it’s a known origin, the plant has isolated itself “enough” that it’s no longer used.
