The Drosophyllum of Spain and Morocco is found in arid hills and pinelands. Like swamps, there is very little nutrients in this soil so the plant makes up for it with carnivory.
The Drosophyllum is covered with sticky tentacles like a sundew, but the glue is even more oily than a sundew (helpful in smothering and suffocating it's prey quicker) and is known to catch prey as large as bees.
Further, some Pinguicula butterworts have been found growing in arid cliffs in Mexico and other Central American countries.
