Family: Asteraceae
Tribe: Heliantheae
Genus: Argyroxiphium
Argyroxiphium is a small genus of five species in the sunflower family (Asteraceae). Its members are known by the common name of silversword or greensword due to their long, narrow leaves and the silvery hairs on some species. It belongs 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.
These perennials are endemic to Hawaii, occurring only on the islands of Maui and Hawaii in an extremely localized distribution. They are primarily found above 1500 m elevation in alpine deserts or bogs, indicating an adaptation to low-nutrient soils. The Kaʻū or Mauna Loa silversword (A. kauense) is the most adaptable: it can be found in rocky lava flows, bogs, and open forest. |
