you are right, in reference to minerals belonging to crystal systems with a pronounced central axis, e.g. hexagonal and tetragonal, basal is redundant as this is the only pinacoid possible. I am also a bit rusty, but these questions are good as rust-removers, so let's walk out on the thin ice...I am sure that the pinacoid situation is more complex in the orthorombic, monoclinic and triclinic ...
