Fam: Asteraceae (Compositae)
Genus: Anthemis L.
Species: Anthemis arvensis L.
English Name: Corn chamomile, Mayweed, Scentless chamomile, or Field chamomileDescription: Annual to biennial (perennial plants). The root is spindle-shaped, semi-woody at the upper part, with lateral branches. Stems single, branched from the base, often lateral branches exceeding the main stem, (5) 20 - 40 (80) cm high, yellow-green, finely longitudinally ribbed, leafy in the lower half, or in the lower 2/3, scattered to densely adherent to or spreading fibers. Leaves simply double to triple feathery-like, sessile, densely to sparsely just fibrous, sessile; shares linearly-lance, up to 0.5 mm wide, pointed, entire or divided. Baskets hemispherical, 7 - 10 mm in diameter, single at the tops of the twigs, on long petioles under the baskets when the fruit ripens most often thickened. The shell at the base is slightly arched; sheath leaves yellow-green, slightly keeled, pointed to obtuse, simply fibrous; outer ovate-triangular, middle and inner – oblong shovel-like or oblong-ovate, membranous at the apex, ciliated. The lingual blossoms are white; tongues 7 - 10 mm long; tubular numerous, yellow. The blossom bed is conical. Bracts elliptically lance, awn-like pointed, keeled, longer than the tubular flowers. Fruit seeds inverted pyramidal, in cross section quadrangular to hexagonal or almost round, 1.8 - 2 mm long, with (6) 9 - 10 (11) wide rounded ribs, with narrow grooves between them, clearly widened at the top - forming a wide wreath or low-pitched crown 0.2 - 0.3 mm high.
Note. There is variability in leaf dismemberment, stem branching and the degree of thickening of the basket petioles from non-thickened or indistinctly thickened to clearly thickened during fruit ripening, which are separated by some authors as subsp. incrassata (Lois.) Nyman (see Thin, 1981).
