hornblende, muscovite (monoclinic) and plagioclase (triclinic), [100] [010] and [001] directions do not correspond to the pole of the respective crystallographic plane (100) (010) (001), except for [010] in the monoclinic system.

In all cases then, the practice for the monoclinic system would be to select a conventional cell based on the shortest vectors in the ac plane (b-axis unique) for primitive as well as centered cells.
