Stemless Thistle

Cirsium scariosum is a species of thistle known by the common names meadow thistle, elk thistle and dwarf thistle. It is native to much of western North America from Alberta and British Columbia, south to Baja California. There are also isolated populations on the Canadian Atlantic Coast, on the Mingan Archipelago in Québec, where it is called the Mingan thistle.

It was first published in Trans. Amer. Philos. Soc., ser.2, vol.7 on page 420 in 1841.
