  Several recent studies indicate that bulges are more complex than merely
structureless relaxed stellar systems. We study the HST images of a sample of
130 nearby early type (S0-Sab) disc galaxies and detect pure structureless
bulges with the Sersic index n > 2 for only 12% of the galaxies. Other galaxies
show varied substructure in their inner regions (inner bars, inner spiral arms,
inner rings) and sometimes contain no bulge at all. Inner substructure is more
common for these galaxies, which also display structure at larger scales.
