Ecology & Natural History

Habitat: Species is adventive in northern Illinois; a more southern plant. It is distributed in muddy stream shores and ditches, sloughs, low ground in moist fields and valleys; along railroads, roadsides, and waste ground.

ILPIN Notes: Disk flowers are perfect and fertile, rays are pistillate - fertile and sterile. PIN says annual, but Midwest references say it is a perennial. In Africa, species is cooked and eaten as a vegetable. It also may contain an alkaloid with nicotine. Species is found in northern U.S., and in Old and New World tropics. It is common in southern 3/4 of the state, and rare to absent elsewhere. Achenes are rugose or warty, slightly hairy at summit. In this genus Eclipta, the pappus may be none, or an obscure crown (complete) or two short awns (complete), thus flower structure is not consistent.
