| In this study, I use floral manipulations in conjunction with marker gene analysis to estimate the relative contributions of autogamy and geitonogamy to self fertilization. |
| Inefficient beetle-pollination and the automimicry system via asynchronous flowering might be responsible for the high level of pollen shortage and frequent geitonogamy. |
| No differences were noted in pollen germination, pollen tube growth or fertilization between experimental tests of xenogamy and geitonogamy in S. mucugensis. |
| Nonetheless, self-crossing is common, but in the form of geitonogamy. |
| Geitonogamy can be due to self-pollination between flowers on the same branch, different flowering branches of the same plant, or different ramets of the same clonal genet. |
| However, the form of dichogamy is likely to have different consequences for autogamy versus geitonogamy. |
