- Two Roman-numeralled rilles associated with Palmieri were part of the original IAU nomenclature of Blagg and Müller. Exactly when the name in its present form was adopted is unclear. - Jim Mosher
What is very curious about the crossing of both rilles on the floor of Palmieri is the rectangle-shaped depression at the very centre of the "X". Which one of the two rilles was first? Or did they appear simultaneously? Are there much more of these rectangle-shaped depressions on the moon? (created by rille crossings).
Named from nearby crater. (Palmieri)
