Abstract
Sideritis royoi is described from limestone rocky habitats of the Port Massif (southern Catalonia, Spain). The species was first collected by the local botanist Lluís de Torres in the late part of the 20th century, but the specimens have remained unidentified positively in herbaria for over 40 years. Sideritis royoi likely belongs to section Sideritis subsection Hyssopifoliae and shows some morphological affinities with the relatively widespread South European species S. hyssopifolia L., but it much differs in having subspinescent upper leaves, main surfaces of the leaves glabrous or glabrescent, the main abaxial surface of the bracts without eglandular hairs, and shorter inflorescences. Weaker similarities were also observed with some species belonging to S. subsection Fruticulosae Obón & D.Rivera. A description for the new orophilous species is provided, along with a detailed illustration, field photographs, and a comparison with closely related species. We include an assessment of its conservation status and a dichotomous key for identification of all the species of Sideritis subsection Hyssopifoliae.
