Taxonomy and name explanation
The basionym for Centranthus calcitrapae (L.) Dufr. is Valeriana calcitrapae L. Carl von Linné , who was the first to give the species this name, took over the name "foliis calcitrapae" from Caspar Bauhin , which means that the leaves are similar to those of the star knapweed ( Centaurea calcitrapa ). "Calcitrapa" is Latin and means the weapon an ankle or crow's foot. Centaurea calcitrapa has spines that look like a crow's foot. Centranthus has no such spines at all; the resemblance relates solely to the leaves.
