マウナ・ケア山
The other subspecies, "Argyroxiphium sandwicense" subsp. "sandwicense" (Mauna Kea silversword), is found on Mauna Kea. They differ primarily in the inflorescence shapebroader in the Haleakalā plants (less than 4 times as long as wide) and narrower on Mauna Kea (4.3–8.6 times as long as wide). The Haleakala subspecies also generally has more ray florets, 11–42 versus 5–20 for Mauna Kea.
