Parietaria deblis Forst.f. is said to be different from Parietaria lustanica Linn. by having patent sepals and asymmetrical achenes as indicated by Ball. l.c. I have sinked the former taxon in the synonymy of Parietaria lustanica as many specimens show continuous variation in sepals and achene characters.
