This paper concentrates on the molecular cloud component in its role as the site of current star formation – especially massive star formation. It is further restricted to the molecular component as traced by CO, the preeminent tracer of molecular gas in galaxies despite the problems discussed here. The basic topics addressed are (1) the variation of CO properties with galactic environment and type; (2) the problems involved in the inference of H2 distributions for individual galaxies from CO observations; and (3) the particular question of the presence of spiral structure in the CO component.
