This yields isoclines of maximum fitness for different floral longevities, that is, combinations of daily floral maintenance (m) together with daily pollen and seed fitness-accrual rates (1 - p and 1 - g) that result in an optimal floral longevities of t = 1, 2, .

Further reductions in m shift optimal floral longevities to still longer durations ([ILLUSTRATION FOR FIGURE 5 OMITTED]).

We found additional support for the model by examining literature data on floral longevity and rates of pollination, for example, species with short floral longevities tended to be those characterized by high rates of pollinator visitation, whereas species with longer-maintained flowers tended to be those characterized by lower rates of pollinator visitation (Ashman and Schoen 1995).
