  1. N complete = number of reproductive structures where the entire stage was observed. N underestimated = number of reproductive structures where a partial stage was observed (had already started development before observation period, or stage not completed at end of observation period). When N is two or more, the standard error (s.e) is provided. Details in Additional file 1.
