Flower ID: IMG_4120.JPG-09-02-2024 Flower name (scientific): Anthemis cotula Linnaeus PY: 1753. Pronunciation guide: (phonetic spelling) AN-tha-miss (or ANTH-e-mis or AN-the-mis or AN-them-is) KOT-ew-luh (or KOT-u-la) Flower name (common): Dog Fennel Family name (common): Aster Family name (scientific): Asteraceae Scientific name origin: Genus: From Greek anthemon meaning flower, a name used by Dioscorides. Also, a name used for chamomile. Specific epithet: From Greek kotule meaning small cup. This refers to the small cups formed at the base of the leaves. It may also refer to the small capitulum, the flower head of this species. Common name origin: The fennel part of the name probably comes from the resemblance of the leaves of Anthemis cotula to those of the Mediterranean herb called fennel, which is Foeniculum vulgare. There are multiple suggestions for the first part of the common name. One refers to the bad smell of the plant in relation to the smell of dogs (note the name origin is at least from the early sixteenth century). Another suggestion is that the plant was placed around dog kennels to safeguard dogs from ticks and other insects. Flower description: Size: 0.6 to 1.3 inches (1.5 to 3.3 cm) Petal count: 10 up to 16 to 20 ray florets, and numerous disc florets. Color: white (ray florets), disc florets yellow. Other: flower arrangement, Solitary Plant description: Size: 6 to 20 inches (15 to 51 cm) Stem hairy: glabrous, glabrate, or puberulent. Other: Leaf description: attachment is alternate, type is compound, 1-2-pinnatisect. Leaves subsessile or short-petiolate. Size: Leaves up to 6 cm long and up to 3 cm wide, terminal segments up to about 4.0 mm in length. Color: medium green Hairy: glabrous to glabrate. Other: Shape: leaf, oblanceolate to elliptic or ovate, 1 to 3 pinnately lobed (MO) Origin (native, introduced, invasive): Introduced Status (common, uncommon, threatened, rare): Common Bloom time (typical): June to October Cycle (annual, biennial, perennial): Annual Habitat: Fields, forest openings, roadsides, disturbed areas, sun. Fruit: Seed: Seeds are light brown in color, about 1.5 to 2 mm long, and ribbed. Importance to wildlife: Similar species (if any): Similar species are Matricaria chamomilla, Tripleurospermum inodorum, and most closely Anthemis arvensis. T. inodorum is scentless when the leaves are crushed, whereas the crushed leaves of Anthemis cotula have a characteristic odor. T. inodorum appears to have a restricted range in Wisconsin, being reported from only 3 northern and 2 eastern counties, whereas A. cotula has been reported from many counties in Wisconsin. Dissection of a flower head for M. chamomilla will show a hollow receptacle, whereas A. cotula has a solid receptacle. A. arvensis has only been reported from two counties in Wisconsin, Grant and La Crosse. The ray florets for A. arvensis are 4 to 17 mm long, the stems are branched mostly proximally, and the receptacle chaffy throughout, whereas the ray florets for A. cotula are 5 to 9 mm long (up to 15+ mm long in some sources), the stems are branched mostly distally or throughout, and the receptacle chaffy only toward the middle.
