P. dentatus is widespread in the Azores and may be found on the islands of São Miguel, Terceira, São Jorge, Pico, Faial, Flores and Corvo. It is less common in Madeira, occurring only on Madeira Island. It can be found growing on damp and sheltered slopes, in gullies, on banks above levadas, and at the edges of roads and forests at elevations of 200–2,300 m (660–7,550 ft) above sea level.
