It is shown that every asymptotically regular or -firmly nonexpansive mapping has a fixed point whenever is a finite union of nonempty weakly compact convex subsets of a Banach space which is uniformly convex in every direction. Furthermore, if is any compatible family of strongly nonexpansive self-mappings on such a and the graphs of , , have a nonempty intersection, then , , have a common fixed point in .
