. In flowers with an extended column, the male part (anther) is distant from the female part (anther) and a pollinator-dependent pollination system is predicted. In flowers with an incurved column, the bent column enables the anther to touch the stigma located at the base of the column, which most likely leads to self-pollination. This automatic self-pollination may act as an efficient reproductive assurance in a pollinator-scarce habitat. During our field observations, no insect was observed to visit the flowers. However, high natural fruit-set (95%, n=5) was observed in

. We hypothesise that the incurved column may be associated with a potential mechanism of delayed automatic self-pollination whereas the straight column may occur at the early stages of anthesis, providing the potential for cross pollination. We dissected flowers on specimens to check the distribution of the incurved column along the inflorescence. We found that both column

occurred on the same inflorescence, and the incurved ones were randomly distributed along the inflorescence. Due to limited specimens (n=5) with limited flowers (3–5 on each) in this study, the timing of the incurving was unable to be confirmed. More field observations of column development in a single flower and the proportion of flowers with incurved column on the whole inflorescence of this species are needed.
