Individual flowers are distinctly dichogamous and protandrous, with a pause of [+ or -] 12 hrs between the male and female phases.
The flowers are dichogamous and partially self-incompatible, and self-pollination results in less seed set than does outcrossed pollination (Hotta, 2004).
Influence of local floral density and sex ratio on pollen receipt and seed output: empirical and experimental results in dichogamous Alstroemeria aurea (Alstroemeriaceae).
Gender-Biased Nectar Production (GBNP) in Dichogamous Plants
The extreme division of labor, with its scout-based search for the most rewarding food sources, allows for an extreme constancy of foragers; thus, they may, for example, harvest pollen from dichogamous flowers (those with male and female functions separated in time) for days and consequently never contact a receptive stigma.
