Dubautia carrii is among the twenty-eight species of silversword plants found only on the Hawaiian archipelago that collectively illustrate the process of adaptive radiation, or the rapid diversification of an ancestral species into different, related species. Each silversword species is physically distinct, with mature plant forms ranging from trees and shrubs to vines. However, they all descended from a common tarweed plant species, with their unique physical characteristics emerging as they adapted to the archipelago's many specific habitats over time.
