During studies of the pollination ecology of I S. tuberosa i in the field, we discovered that the flowers of I S. tuberosa i could secrete red colored nectar at~ 8: 00 PM after the flower beginning to close after sunset (Figure 1b). The colorless nectar of the white flower mutant together with the absence of nectar in experimental removals of stamens showed that the pigment of colored nectar of I S. tuberosa i appeared to stem from red-purple stamens.[Extracted from the article]Copyright of Ecology is the property of Wiley-Blackwell and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission.
