Highly branched shrub up to 4 m, with a woody base and striated, sericeous branches. Leaves are simple or trifoliate, sessile, elliptic to linear. Flowers are bright yellow and emerge singly at the end of the branches. Fruits are yellow legumes, densely silvery-pilose and contain 6-8 seeds. This native of La Palma is found in high montane zones above 2,000 m, near the Roque de los Muchachos and surrounding areas. Until recently, it was one of the most endangered species in the Canaries. However, the considerable efforts of local government and extensive replanting within the boundaries and surrounding areas of the Caldera de Taburiente National Park have ensured that it is currently not under threat. Just over 360 specimens have been counted in their natural habitat, distributed in five different populations, whose main threats are grazing animals, competition with other species and forest fires. Total numbers, bearing in mind replanting, currently stand at around 3,000 specimens. This species is closely related to Genista tenera or Madeira broom, a native of Madeira.
