It is inevitable that understanding of some indicators of stellar evolution is not so definite as we could wish. This can be equally true of observational material and of the beginning and intermediate stages of theoretical development. Even though these matters may be arguable and untidy, they are not negligible and, in fact, represent obvious recognized opportunities for the near future. It is possible that these matters are really the most valuable consequence of the meeting. Subject matter of this kind was presented at the JD8, in both invited and contributed forms, and their summaries follow here in the same approximation to stellar evolution stages that characterized Part II.
