Sanicula Linnaeus. Sanicle, Snakeroot.

Key to Sanicula

A genus of about 41 species, herbs, nearly cosmopolitan (Plunkett et al. 2018).

Key advice:Most Sanicula species cannot be reliably determined from sterile plants; fruits or flowers are required for identification. An important character is the length of the styles in relation to the calyx and/or to the bristles on the fruit. In the longer-styled species, the styles are slender and curved outward, sometimes enmeshed in the bristles, but distinctly longer than them and also longer than the calyx. In the shorter-styled species, the styles are straight to slightly curved, shorter than or about as long as the bristles, and more or less included in the calyx. In most species the calyx is inconspicuous, but consists of 5 deltoid to narrowly triangular (or even subulate) calyx lobes, 0.4-2.0 mm long, at the summit of the schizocarp (the fruit).
