Figure 1.
Mass-flowering years of Strobilanthes flexicaulis.
Flowering records of Strobilanthes flexicaulis at Mt. Yae and Mt. Katsuu are shown as mass flowering (large red circles), few flowers (small orange circles), no flowers (blue crosses), and non-mass-flowering (green triangles), when we have no records of flower counts. *This mass-flowering was observed by K. Nakajima (personal communication).

Life history of Strobilanthes tashiroi.
One hundred eight flowering individuals of Strobilanthes tashiroi were labeled in 2009. These individuals were pursued until 2011 and examined conditions (flowering, non flowering or dead) in each year. Three year consecutive flowering in S. tashiori clearly shows it is a polycarpic perennial plant.

Surveys of fruit predation rates.
All the fruits on a plant before the capsules were exploded, were examined in Mt. Yae population at the end of March or the beginning of April from 2009 to 2011. The number of flowers examined was shown on each bar. * Fruit predation rates in the mass-flowering year (2010) were significantly low with the chi-square test (Text S3).
