Bentham referred to Thlaspi heterophyllum DC.? The query sign (?) indicates that Bentham was unsure whether his L. heterophyllum and DC.'s T. heterophyllum are the same. Therefore, L. heterophyllum is construed to be a sp. nov. (IPNI)

Dans sa flore Bentham met bien en doute la synonymie avec le Thlaspi heterophyllum de De Candolle, mais cela serait cependant à revoir.
