Euphorbia davidii

Euphorbia davidii, known as David's spurge or toothed spurge, is a species of flowering plant in the spurge family Euphorbiaceae.[2][3] It is an annual herb growing up to 2 feet (0.61 metres) tall.[4] Leaves are opposite in arrangement with narrow to broadly elliptic blades.[4]

Distribution and habitat

Euphorbia davidii is native to parts of southwest and central North America.[3] It is apparently not native to eastern and northern North America, South America, Australia, Russia, and other areas where it occurs worldwide. Euphorbia davidii is found in a variety of habitats, from forests, riparian areas, and prairies, to gravel roadsides and railroads.[3][5]

As a pest

In March 2021[6] the EPPO (European and Mediterranean Plant Protection Organization) added E. davidii to its Alert List due to concerns it may move beyond its current habitats - railway lines - and into agricultural lands; and because it recently appeared in Central Russia.[7]
