Final Conclusion

Also included in this tribe are the widespread species of Convolvulus, in which Calystegia previously was included, and the genus Polymeria, endemic to Australia. Individual Calystegia flowers bloom only for a single day, but they offer both pollen and nectar rewards to potential pollinators so they attract a broad array of insects. Bees are the most important pollinators.
