I think so...this paper says Laserpitium is polyphyletic, puts it in Siler, but says Siler has only one species, not 4 (as POWO and iNat has it). But that one species is S. montanum.

This taxon change looks OK at my cursory reading, though I started a flag for the genus here https://www.inaturalist.org/flags/535707
