The new species Phlomoides binaludensis (Phlomideae, Lamioideae, Lamiaceae) from Binalud Mountains in the Khorasan province in NE Iran, is here described and illustrated. It belongs to Phlomoides section Filipendula and resembles P. labiosiformis and P. laciniata in general morphology, but differs primarily in corolla and calyx size, corolla color and stem indumentum.
