Māmaki (Pipturus albidus) is endemic to Hawai’i, meaning it’s only found naturally in the Hawaiian Islands. It originates from the nettle family, but unlike its stinging relatives this species has evolved in Hawai’i without needing those defenses. It’s widely known as a medicinal tea, but its connection to the natural world is much more far-reaching culturally as well as biologically.
