Under normal (or natural)conditions, the duration of the life cycle of any speciesmay vary considerably because perhaps of inherited vigoror environment or both. For instance, in a sowing of garden carrots a few plants may runto seed the first season, though the general life cycle of this veg-etable is two years; conversely, some annuals, as radish, may fail toseed the first year, but send up flower stalks the following cases are, however, excepti
