Fig. 3.

Total range sizes and proportions of their arctic partial ranges in taxa of Ranunculus, Coptidium, and Halerpestes represented in the flora of the Arctic, according to the size categories defined in “Material and Methods.” Circle sizes denote the number of taxa belonging to each combination of total range size/arctic partial range. Taxa with small entire ranges confined to the Arctic are shown in the top left-hand corner, and widespread circumpolar taxa with occurrence only at the margins of the Arctic are shown in the bottom right-hand corner. Taxa names are arranged close to their respective circles.
