Tagabili is a stout, sometimes slender, erect, more or less hairy, branched annual 0.5 to 2 meters in height. Leaves are lanceolate to oblanceolate, 6 to 15 centimeters long, 1 to 4 centimeters wide, and coarsely toothed or sublobed in the margins. Panicles are terminal and ample, bearing numerous, peduncled, narrowly ovoid, flowering hears 6 to 7 millimeters long. Bracts are green. Flowers are many in each head, greenish-white.

• Chemotaxonomic Significance:Previous studies have considered Erigeron bonariensis as synonym of Conyza bonariensis. The study suggests Erigeron and Conyza are two different genera. On basis of chemotaxonomy, study concludes the title species is Erigeron bonariensis.
• Phytochemical Analysis: Study yielded a new compound, an aromatic glycoside, erigoside G, together with nine known compounds.
