Allopolyploid species of Nicotiana (Solanaceae) and their parental diploid species. Note that the floral morphology of three of the polyploids, N. repanda, N. nesophila and N. stocktonii (allotetraploids, 2n = 48), is like that of N. sylvestris (a diploid, 2n = 24), adapted for nocturnal hawk-moth pollination, and the fourth, N. nudicaulis, is like that of the other parent, N. obtusifolia (2n = 24), adapted for bee pollination during the day. Photographs taken by Kar Yoong Lim.
