Flower ID: IMG_3172.JPG-09-01-2019 Flower name (scientific): Bidens connata Muhlenberg ex Willdenow PY: 1803. The FNA suggets Bidens connata may be better treated as part of B. tripartite L. PY: 1753. Pronunciation guide: (phonetic spelling) BI-denz kon-NAY-tuh Flower name (common): Purple-stem Beggarticks Family name (common): Aster Family name (scientific): Asteraceae Scientific name origin: Genus: From the Latin bis for two and dens a tooth, hence two teeth. Referencing the bristles (two-awned) on the achene (dry one-seeded fruit). Specific epithet: From the Latin for joined, or united, referencing the incompletely divided lower leaves. Common name origin: For the usual color of the stem. Beggarticks is a common name applied to more than one of the Bidens species. The name beggarticks probably alludes to the irritant weedy nature of the plants and the clinging character of the achenes, attributes appropriate to a beggar. It might also reference the grasping nature of the achenes as being similar to the unwelcome clinging character of ticks, with an allusion to a beggar. Flower description: Size: 0.2 to 0.5 inches (5 to 13 mm) Petal count: 0 ray florets usually, sometimes 1 to 5 or more; disc florets typically 20 to 40. Color: yellow Other: flower arrangement, Solitary Plant description: Size: 8 to 80 inches (20 to 203 cm) Stem hairy: Typically glabrous. Other: Leaf description: attachment is opposite, type is simple and lobed Size: Leaves are typically 4 to 10 cm long but may exceed 20 cm in length and typically 1 to 3 cm wide but may reach up to 7 cm wide. Color: Upper surface medium green, lower surface pale to medium green. Hairy: Typically glabrous to glabrate. Other: Shape: leaf, elliptic to lanceolate (FNA), to oblong-lanceolate (IL) Origin (native, introduced, invasive): Native Status (common, uncommon, threatened, rare): Common Bloom time (typical): August to October Cycle (annual, biennial, perennial): Annual Habitat: Wet soils, streambanks, swamps, marshes, ponds, shores, sun or part shade. Fruit: Seed: Dark brown to blackish, about 6 mm in length (excluding awn),and awns about 2 to 5 mm in length. Importance to wildlife: Similar species (if any): Some of the Bidens are similar to each other. Flower head size, number of awns on the seed, number of bracts, presence or absence of ray florets, and leaf differences can help ID the seperate species. Some data for Bidens species: B. cernua flower 25 - 51 mm, 2 - 4 commonly 4 awns; B. connata flower 6 - 13 mm, 2 - 4 awns; B. discoidea flower 3 - 8 mm, 2 awns; B. frondosa flower 19 mm, 2 awns; B. trichosperma flower 38 - 51 mm, 2 awns; B. tripartita flower 13 - 19 mm, 3 awns; B. vulgata flower 25 mm, 2 awns. Species B. beckii is aquatic, species B. aristosa is uncommon in Wisconsin, and species B. pilosa can be identified by its white to pinkish ray florets. The flowers of B. discoidea are probably the closest lookalike to Bidens connata.
