Expanding Envelopes of Stars,se is complicated by the known binary nature of many Wolf-Rayet stars. Other groups of stars possessing envelope-like structures — U Gem stars and old novae, symbiotic stars, and T Tauri stars — are briefly mentioned. The problems of stellar envelopes, first listed by Struve thirty years ago, are still unsolved.

We draw attention to the partially unexplored but probably very interesting properties of coronae of helium-rich stars.
