Habitat & Geographic Range

Common corncockle

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Complex-leaved Dandelion

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Denmark, Norway, and Sweden.

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.

Complex-leaved Dandelion

<em>Taraxacum subundulatum</em>, the complex-leaved dandelion, is a perennial herbaceous plant in the family Asteraceae belonging to the extraordinarily diverse and taxonomically complex genus Taraxacum, which contains hundreds of microspecies primarily reproducing via apomixis — asexual seed production without fertilisation. This species has been documented from Denmark, Norway, and Sweden, where it inhabits meadows, grasslands, roadsides, and disturbed ground typical of the Taraxacum genus across temperate Europe. Like other dandelions, it produces a basal rosette of typically lobed or undulate leaves, a hollow leafless scape, and a characteristic composite flower head of yellow ray florets that matures into the familiar globular seed head for wind dispersal. The species is Not Evaluated on the IUCN Red List, consistent with the treatment of most Taraxacum microspecies, whose abundance and taxonomic complexity make formal threat assessments difficult. Dandelions generally tolerate a wide range of environmental conditions and are resilient to disturbance. The complex-leaved dandelion likely plays typical dandelion ecological roles as an early-season nectar source for pollinators including bees and hoverflies, and as food for specialist insects. Biological traits including average lifespan, population size, and detailed morphological dimensions specific to <em>Taraxacum subundulatum</em> remain poorly documented given the challenges of distinguishing microspecies within the aggregate.
