Successive stamen movement in Saxifraga candelabrum is responsive to weather and pollinator visits.

At within-flower level, rather than an equal packaging scheme, pollen production per anther had an increasing trend with the order of bending in flowers of S. candelabrum (pollen = 121.93×order 2 – 598.51×order + 16345.47, R 2 = 0.17, F 1,144 = 30.91, P < 0.0001; Fig. 4 B).
