The frequency of polyploidy in the angiosperm flora of the Ogotoruk Creek-Cape Thompson area of northwestern Alaska is correlated with edaphic environmental gradients in the area. These results, when placed in a historical and ecological context, help to clarify the problem of increasing frequency of polyploidy with latitude in the northern hemisphere.
