Sanicula crassicaulis is a species of flowering plant in the family Apiaceae known by the common names Pacific black-snakeroot and Pacific sanicle.

Description

It is a perennial herb producing a thick stem up to 1.2 meters tall from a taproot. The leaves have blades up to 13 centimeters long which are divided into a few deep lobes and edged with small teeth. The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, yellow petals (var. tripartita flowers may range from yellow, brown, or purple). Each head has approximately five leaflike, lance-shaped bracts at its base. The rounded fruits are a few millimeters long, covered in curving prickles, and borne in small clusters.

Distribution and habitat

Sanicula crassicaulis has an amphitropical distribution and is native to the west coast of North America and southern South America.

In North America, it ranges from British Columbia to Baja California, where it can be found in many types of habitat, including mountain slopes, grassland, and woodlands. In South America, it ranges from Coquimbo Region to Los Lagos Region in Chile, and Chubut Province, Neuquén Province, and Mendoza Province in Argentina. It is also introduced to the Juan Fernández Islands, where it is invasive.
