The mass distribution of central stars of planetary nebulae, as recently derived for the IUE ensemble by Heap and Augensen (1987), is shown to be strongly dependent on the assumed distance scale. Old and new arguments for galactic as well as extragalactic PN are given which favor the use of increased distances. In some cases minimum distances are derived from spectroscopic data without the use of evolutionary tracks. If these are applied the mass distribution of the IUE ensemble turns out to be identical with that derived from optical data by Schoenberner especially the strong peak at low masses, around 0.6 solar mass, is recovered. The fraction of CPN with masses smaller than 0.64 solar mass increases from 44 to 77 percent a value which is much more in agreement with independent results for white dwarfs or stars leaving the asymptotic giant branch. Birth rates and scale heights of CPN and white dwarfs become also more comparable.
