--><p>Cota, sometimes a subgenus of Anthemis, is distinguished by its obcompressed and indistinctly ribbed cypselae; plants of Anthemis in narrow sense usually have ± terete cypselae with 10 distinct ribs. Additional differences include cytological, phytochemical, and molecular traits.</p><!--
--><p>Apparently, Cota altissima (Linnaeus) Gay (Anthemis altissima Linnaeus) was reported from Oregon in error (L. Abrams and R. S. Ferris 1923–1960, vol. 4). No specimens of C. altissima from Oregon have been located, and the taxon has been specifically excluded from the Oregon Flora checklist (K. L. Chambers and S. Sundberg, www.oregonflora.org).</p><!--
--><p>Cota austriaca (Jacquin) Schultz-Bipontinus (Anthemis austriaca Jacquin), a European species, has been reported as established near Pullman, Washington (specimen in UC); it differs from C. tinctoria in having an annual or biennial habit, subhirsute phyllaries, and white ray laminae (R. Fernandes 1976).</p>
