6 named features carry the IAU descriptor Palus — a small dark plain on Mars, out of 9 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 6 paludes with a recorded origin, 3 categories appear, led by Greek.
Every one has its own page, on the surface it sits on.
The same descriptor is used on 1 other world, for 3 more features.
