Widely distributed across Europe (8 countries), North America (Canada, United States), and Oceania and the Pacific (Australia).

Common corncockle

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.

Common Marsh Bedstraw

<em>Galium palustre</em>, the common marsh bedstraw, is a scrambling herbaceous plant in the family Rubiaceae, distributed across Europe, North America, and Oceania. It is classified as Least Concern on the IUCN Red List. This species typically grows in wetland habitats including fens, marshes, wet meadows, ditches, and the margins of rivers and ponds, where it climbs through taller vegetation using tiny hooked bristles on its stems and leaves. Common marsh bedstraw produces small, white, four-petalled flowers in loose clusters during summer months. Like other members of the genus Galium, its stems are distinctively square in cross-section. The plant plays a modest role in wetland ecosystems, providing cover for invertebrates and contributing to the structural complexity of marginal vegetation. Its widespread distribution across three continents and tolerance for a range of wetland conditions contribute to its secure conservation status. The species has limited documented economic uses but is ecologically representative of healthy freshwater marginal habitats.
