Swap to correct spelling variant.

See: https://www.inaturalist.org/flags/544861. Dendrobium eburneum is accepted as a synonym of Dendrobium draconis. However, use on iNat is as an unpublished or illegitimate combination of Tropilis eburnea in Dendrobium. As both ALA and Powo accept that name as a synonym of Dendrobium aemulum, that is where I am putting the IDs.

If we are accepting the rest of Jacobaea, it doesn't make sense to have a single exception.

IPNI lists the name "Jacobaea arenaria" as invalid, as the attempt to publish it (http://old.ssbg.asu.ru/turcz/p58-63.pdf) failed to cite the location of publication of the "basionym" (https://ipni.org/n/20004937-1). Even were this not the case, though, the publication acknowledges that Senecio arenarius M.Bieb. is an illegitimate later homonym of Senecio arenarius Thunb. As such, it cannot act as a basionym, and the name "Jacobaea arenaria" would be treated as a replacement name. However, the authors listed Senecio grandidentatus in synonymy, and according to Article 11.4, should have taken the epithet from this name rather than publishing a replacement name. This combination was subsequently published, and is the correct name for this taxon.
