Scented nectar secreted by flowers is an interesting natural phenomenon in angiosperms that is often overlooked by most researchers. Scented nectar is an evolutionary feature coupling the behavior between flower-visitors and their rewards. The effect of scented nectar on pollinator or nectar-thief is a scientific problem which deserves further exploration. We evaluated Mucuna sempervirens flowering dynamics, floral nectar volatiles, behaviors of Dremomys pernyi and Callosciurus erythraeus to inflorescence opening, nectar’s attraction effect to Apis cerana cerana, and the toxic effect of M. sempervirens nectar to Tapinoma sp. Aliphatic compounds (87.2%) were the main volatiles in nectar of M. sempervirens, whereas ketones accounted for 56.1% of the total volatiles. Lastly, volatile components with sulfur elements were absent from nectar samples. Previous studies of bat pollinated plant species have found that plants in the genus Mucuna always release sulfur compounds. Additionally, we found that the nectar of M. sempervirens was poisonous to Tapinoma sp. ant species, whereas it attracted A. cerana cerana using the Y olfactory bioassay. Squirrel species (D. pernyi and C. erythraeus) were effective pollinators of M. sempervirens, so we suspected that M. sempervirens might not be pollinated by bats only. This study provides data of pollination
