Cirsium setidens is aperennial plant up to 100–120 centimetres (39–47 in) tall.[3]Radical leaves and lowercauline ones become withered when the flowers bloom. Mid cauline leaves are arrangedalternately,ovate or widelanceolate, green, and 15–35 centimetres (5.9–13.8 in) long, with tapering end,spiny oreven margins, andleafstalks.[3] The upper space of the leaves is hairy, while the underside is usually white-tinged without hair. Upper cauline leaves are smaller, lanceolate with pointy ends, shorter leafstalks, and spiny margin. The roots are erect.[3]
Purpleflowers bloom from July to October.[3] Thecapitula are quite large – about 3–4 centimetres (1.2–1.6 in) in diameter.[3] Each capitulum is on the tip of a branch or the main stem.[3] Theinvolucres are bell-shaped, 20 millimetres (0.79 in) long and 20–30 millimetres (0.79–1.18 in) wide, withspider-web-like hair. Theinvolucels, with pointy ends and sticky underside, are arranged in seven rows.[3] Thecorollas are purple, about 15–19 millimetres (0.59–0.75 in) long. The fruits areachenes, each 3.5–4 millimetres (0.14–0.16 in) long. Thepappi are brown, about 11–16 millimetres (0.43–0.63 in) long.[3]
