Wikipedia
Septentrional, meaning "of the north", is a word rarely used in English, but is commonly used in Latin and in the Romance languages. The term septentrional usually is found on maps, mostly those made before 1700. Early maps of North America often refer to the northern- and northwestern-most unexplored areas of the continent as at the "Septentrional" and as "America Septentrionalis", sometimes with slightly varying spellings.
The term septentrional is the adjectival form of the Latin noun septentrion, which refers to the seven stars of the Big Dipper asterism, the Septentrion.
