Rhinanthus osiliensis

Rhinanthus osiliensis, in English known by the common name Saaremaa yellow rattle, is a flowering plant in the genus Rhinanthus in the family Orobanchaceae. It is endemic to the Estonian island Saaremaa in the Baltic Sea. Plants growing on the Swedish island Gotland have been ascribed to R. osiliensis, too, but genetic analyses have not supported this hypothesis.[1][2]
