Sanicula mariversa
Sanicula mariversa is a rare species of flowering plant in the family Apiaceae known by the common name Waianae Range black-snakeroot. It is endemic to Hawaii, where it is known only from the Waianae Mountains on the island of Oahu. It is threatened by the degradation of its habitat. It is a federally listed endangered species of the United States.
This plant produces erect, branching stems 40 to 70 centimeters long from a thick caudex. The leaves have leathery, dark green, heart-shaped or kidney-shaped blades up to 15 centimeters long by 23 wide which are palmately divided into three to five dissected lobes. The inflorescence is a cluster of many tiny yellow flowers, each flower measuring only about a 0.1 centimeter long. The fruit, measuring about half a centimeter long, is covered in hooked prickles.
