- ItemOpen AccessThe reproductive biology and ecology of Colchicum (Colchicaceae) in southern Africa(2008) Kleizen, Ciara; Midgley, Jeremy J; Johnson, StevenThe purpose of this study was to detennine if the rodent pollination system extends to Colchicum, as predicted by Johnson et al. (2001), to test the importance of floral scent for attraction of rodent pollinators, and to investigate the factors that influence seed set in populations.

- ItemOpen AccessThe reproductive biology and ecology of Colchicum (Colchicaceae) in southern Africa(2008) Kleizen, Ciara; Midgley, Jeremy; Johnson, StevenThe observation that many plants have developed sets of structural and functional adaptations that encourage visitation by pollinators has led biologists to define pollination syndromes. These syndromes reflect patterns of convergent evolution and serve to generate hypotheses about potential pollinators based on a plant's morphological characteristics (Faegri and van der Pijl, 1979; Johnson and Steiner, 2000).
