We propose that the dominant fraction of the $B \\to \\eta' +X_s$ rate is due mainly to $b \\to s g^*$, where $g^*$ is an off-shell gluon, followed by $g^* \\to g\\eta'$ via the anomalous coupling of the $\\eta'$ to two gluons. The calculated rate for $B \\to \\eta'+X_s$ is in rough accord with experiment using a fairly constant glue-glue-$\\eta'$ form factor. This behavior of the form factor may be indicative of glueball dominance of the channel. Searches via the modes $\\eta' h^+h^-$ ($h=\\pi$ or $K$) may be worthwhile.
