【 摘 要 】

We investigated the pollination and reproductive biology of two Canary Island endemics, Solanum vespertilio and S. lidii (Solanaceae). We measured male function (pollen development), female function (fruit initiation) and spatial arrangement of reproductive parts within flowers and inflorescences. Furthermore, we observed flower visitors and monitored visitation rates. Both species of Solanum display andromonoecy: Longstyled flowers are functionally hermaphrodite and borne proximally on the inflorescences, while short-styled flowers are functionally male and borne distally on inflorescences. Large bees capable of buzzing were the main flower visitors. In particular, the endemic Canarian bumblebee, Bombus terrestris canariensis, was a frequent visitor and pollen vector of S. vespertilio.
