Figure 3From: Geological and climatic changes in quaternary shaped the evolutionary history of Calibrachoa heterophylla, an endemic South-Atlantic species of petuniaCollection site location. a) Map showing the sampling sites. The colors of the populations are related to the haplogroups identified by the network and Bayesian chronogram. Dotted lines represent paleochannels [40, 51]. b) Calibrachoa heterophylla flower.Back to article page
