This specimen seems to have a determination on the orginal label as
Helianthemum guttatum, by Cosson.
Later on, Willkomm added var. eriocaulon (greek letters stand for varieties). The fact that he added the "a" letter at the begining means that he refers with this det. to the plant on the left? Maybe
In any case, having two determinations seems right: one at the species level by Cosson, and a more recent one by Willkomm at the variety level, as the current version on the catalogue:
