Summary:

The Hawaiian silversword alliance, (Compositae Madiinae), includes 28 species in three endemic genera, (Argyroxiphium, Dubautia, and Wilkesia). This is a premier example of adaptive radiation in plants as they have a wide variety of geographical distributions and elevation ranges within the archipelago and grow in habitats as varied as dry scrub and woodland, wet scrub and forest, cinder and lava, and bog. Ecological diversity is also evident among sympatric species. As a result, the objective of this study was to provide insight into the ecological, morphological, and physiological diversity of species in the silversword alliance.
