It was first described in 1842 by Thomas Nuttall, [2][1] and its specific epithet, coriacea, derives from the Latin, corium, which means leather, and describes the tough, thick, leathery leaves.[6]


Description

Dwarf naupaka is a low, flat-lying perennial herb. Its older stems are somewhat woody, and the succulent leaves are oval-shaped, relatively far apart, and smooth or somewhat scaly with rounded tips. Flowers occur in branched inflorescences from the point of leaf attachment in groups of one to three.[7]

Conservation

Today, dwarf naupaka exists only on Maui and two offshore islets. Historically, it could be found on six islands. The total population is less than 300 plants, making dwarf naupaka an endangered species.[7][5]
