''Isocoma tenuisecta'', commonly called burroweed, shrine jimmyweed, or burrow goldenweed is a North American species of small, flowering perennial herbs in the sunflower family. It is native to Arizona, New Mexico, and Sonora.〔(Biota of North America Program 2014 county distribution map )〕〔(SEINet, Southwestern Biodiversity, Arizona chapter ) photos, description, distribution map〕 ''Isocoma tenuisecta'' grows 1 to 3 feet (30-90 cm) tall. Leaves are narrowly lance-shaped, with numerous large teeth or small lobes along the edges. The leaves are glandular and lobed. The plant flowers in September through November, with clusters of heads at the ends of branches and on top of the main stem. Each head contains 8-15 yellow disc flowers but no ray flowers. The old heads turn dry and tan and remain on the plant after the achenes have dispersed.〔(Flora of North America, ''Isocoma tenuisecta'' Greene, 1906.
