Range DescriptionArgyroxiphium sandwicense ssp.macrocephalum is endemic to the upper slopes of Mauna Kea on Hawaii. It appears to have been formerly abundant. Today, however, there is only a single naturally occurring population which comprises about 41 naturally occurring plants. Plants have been outplanted at several sites on Mauna Kea. These outplanted individuals and their progeny number almost 4,000 individuals, but these do not yet qualify to be counted as mature individuals.
