Sterigmostemum laevicaule, described by Bornmüller in 1910, has been a nomen dubium since the single specimen ever known was destroyed in Berlin-Dahlem in 1943. A search in the type locality produced evidence that the description actually refers to Erysimum crassicaule, a name that has priority. A corresponding neotype is designated for S. laevicaule.
