The conclusion by Maeder et al.(1980) that the strong gradient in NR/NWR results from the effect of metal content on the rate of mass loss is reconsidered. We suggest that the above gradient simply reflects a simi lar gradient in the progenitor stars, although effects of metallicity cannot be excluded.
