Bidens infirma, commonly known as awnless beggarticks, is a herbaceous annual plant belonging to the Asteraceae family. This species is recognized for its specific morphological traits that distinguish it within the diverse *Bidens* genus. Its significance lies primarily in its role within its native ecosystems and as a subject of botanical study. Physically, *Bidens infirma* is characterized by its erect to spreading growth habit, typically reaching heights between 20 and 80 centimeters. The stems are generally smooth or sparsely pubescent. Its leaves are opposite, simple, and lanceolate to ovate in shape, measuring approximately 3 to 10 centimeters in length and 1 to 3 centimeters in width. The leaf margins are usually serrated. The plant produces composite flower heads, characteristic of the Asteraceae family, which are borne on slender peduncles. Each flower head typically consists of ray florets and disc florets. The ray florets are usually white and relatively small, while the disc florets are typically yellow. The fruit is an achene, which in this species lacks the awns that are characteristic of many other *Bidens* species, hence the common name "awnless." These achenes are often flattened and may have small, wing-like appendages. The native distribution of *Bidens infirma* is primarily within the southeastern United States. It is found in states such as Alabama, Florida, Georgia, Mississippi, and South Carolina. This species typically inhabits moist, open habitats, often found in sandy soils, prairies, savannas, pine flatwoods, and along the edges of ditches and roadsides. It thrives in areas that receive full sun to partial shade. While not widely cultivated, its natural habitat preferences suggest it would perform best in well-drained, moist soils in sunny or partially shaded locations. Ecologically, *Bidens infirma* plays a role in supporting local insect populations, particularly pollinators that visit its flowers. Its seeds are dispersed by various means, including wind and attachment to animal fur or clothing, though the absence of prominent awns influences the latter. There is no established ornamental, agricultural, medicinal, culinary, or economic importance documented for *Bidens infirma*. Its primary value is botanical, contributing to the biodiversity of its native regions. An interesting characteristic of *Bidens infirma* is its name, derived from the Latin *Bidens*, meaning "two-toothed," referring to the common feature of awns on the fruits of many species in this genus, although this specific species is notable for the absence of these awns. This adaptation, or lack thereof, influences its seed dispersal mechanisms compared to its awned relatives. The plant's ability to thrive in disturbed or open habitats suggests a degree of resilience and adaptability to changing environmental conditions within its native range.
