    started disseminating pollen at 1-2 d after flowering, and lasted for 5-6 d. Pollen viability could be preserved for more than 10 d at normal temperature. High seed rate from the stigma was observed at 1 d before flowering to 3d after flowering, and the dissemination hysteresis was defined as protogyny. The P/O ratios were 6,124 to 9,713:1, suggesting that the larger quantity of pollen to increased the seed setting rate. Three species of bees, eight species of beetles, seven species of syrphid flies, four species of ants, and three species of butterflies were observed on the flowers.

    of the visitors' species showed bees being the most important pollinators. Beetles and ants participated in pollination to some extent and were unstable. Syrphid flies and butterflies were very unreliable with low pollination efficiency. Reproductive success depended largely on cross-pollination assisted by pollinator activities, especially the bees.
