Sanicula crassicaulis is a species of flowering plant in the family Apiaceae known by the common names Pacific black-snakeroot[1] and Pacific sanicle.

Description

[edit]

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.[2]

Distribution and habitat

[edit]

Sanicula crassicaulis has an amphitropical distribution and is native to the west coast of North America and southern South America.[3]

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.[4][5] In South America, it ranges from Coquimbo Region to Los Lagos Region in Chile, and Chubut Province, Neuquén Province, and Mendoza Province in Argentina.[6] It is also introduced to the Juan Fernández Islands, where it is invasive.[7]
