The resource on Pipturus albidus (māmaki) from UH CTAHR describes this Hawaiian endemic plant, including its physical characteristics, such as ovate leaves with wavy toothed edges and light gray undersides, and its habitat in moist to wet forests across most Hawaiian islands. It highlights traditional uses of māmaki for making tapa cloth, medicine, and tea, and notes its importance as a food source for the Kamehameha butterfly caterpillar.
