Alpine Rock-Cress

The Alpine Rock-Cress (Arabis alpina) is a species in the genus Arabis. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions. Widely distributed across Europe (10 countries), North America (Canada, United States), and South America (Argentina).

common broomrape

The common broomrape (<em>Orobanche minor</em>) is a parasitic flowering plant with an exceptionally wide global distribution, occurring across Africa, Asia, Europe, North America, Oceania, and South America, and typically inhabiting tropical and subtropical forests and grasslands. This species is classified as Near Threatened on the IUCN Red List, indicating that its populations may be declining in some parts of its range. As a member of the family Orobanchaceae, the common broomrape is a root parasite that attaches to the roots of host plants, most commonly members of the legume and carrot families, from which it draws all of its nutrients. It lacks chlorophyll and therefore cannot photosynthesize, making it entirely dependent on its host for survival. The species often produces spikes of yellowish or purplish tubular flowers above the soil surface during spring and summer across its diverse geographic range. Biological traits of this species remain poorly documented in the scientific literature.
