The lowest possible rate of
growth of a meromorphic function f of genus q with zeros and poles restricted to a
given finite set of rays through the origin is determined in terms of q and the rays
carrying the zeros and poles. For α > 1 the ratio T(αr,f)∕T(r,f) is shown to be
bounded as r tends to infinity for all such entire functions, but not for all such
meromorphic functions.
