Gutierrezia tortosae Ratto & Adr. Bartoli, a new species from Argentina, is described and illustrated. The new species resembles Gutierrezia mandonii (Sch. Bip.) Solbrig, in having xylopodium, similar shaped leaves, and yellow ray florets, but differs by having erect and rigid stems, erect leaves and smaller heads. A key to differentiate it from the allied species which inhabit in the northwest of Argentina is provided.
