We compare the metal-rich globular clusters within 3 kpc of the galactic center with the underlying stellar population. On the basis of kinematics, spatial distribution, and metallicity, we argue that these clusters may be associated with the galactic bulge (as concluded by Frenk & White 1982) rather than with the…
