But Gentianella, a dwarf gentian species; of course they do look completely different from autumn crocusses:
This one here is Gentianella austriaca (Österreich-Kranzenzian), oftentimes wrongly classified as G. germanica - but this species here (or probably sub-species, but that's not the point in this case) looks significantly distinct from G. germanica, the latter isn't even native to Austria. Found on Perchtoldsdorfer Heide, that tiny and endangered heath just outside the city limits of vienna.
