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 Tule

<em>Schoenoplectus acutus</em>, commonly known as common tule or hardstem bulrush, is a tall emergent aquatic plant in the family Cyperaceae native to wetlands across North America, particularly abundant in the western United States and Canada. It is a dominant species in freshwater marshes, lake margins, river edges, and tidal wetlands, forming extensive stands that provide critical habitat and ecosystem services. The stems are stiff, sharply triangular in cross-section, and can reach heights of up to 3 meters, with inflorescences of reddish-brown spikelets emerging near the tips. <em>Schoenoplectus acutus</em> typically grows in standing or slow-moving water up to 1 meter deep and is highly tolerant of fluctuating water levels. This species played a fundamental cultural role for many Indigenous peoples of western North America, who used the stems for basketry, boat construction, and thatching. Ecologically, tule marshes provide nesting habitat for numerous bird species, shelter for fish and invertebrates, and serve as important carbon sinks. The species is currently assessed as Least Concern by the IUCN. Its widespread distribution and abundance ensure population stability, though localized wetland loss remains a concern in many areas. Biological traits such as average plant lifespan, stem dimensions, and above-ground biomass are well-studied in ecological contexts but individual-level weight measurements remain poorly documented.
