Argyroxiphium is a small genus of plants in the family Asteraceae.[2][3] Its members are known by the common names silversword or greensword due to their long, narrow leaves and the silvery hairs on some species. The silverswords belong to a larger radiation of over 50 species, including the physically different genera Dubautia and Wilkesia. This grouping is often referred to as the silversword alliance.[4] Botanist P. H. Raven referred to this radiation as "the best example of adaptive radiation in plants".[5]
