Retama

According to Wikipedia : "Retama is a genus of flowering bushes in the legume family, Fabaceae. It belongs to the broom tribe, Genisteae. Retama broom bushes are found natively in North Africa, the Levant and some parts of southern Europe. The GRIN database lists three species: Retama raetam, Retama monosperma, and Retama sphaerocarpa.[1] The first two of those have white flowers, while the third has yellow flowers. It remains an open question in taxonomy whether the members of the Retama genus should be incorporated into the Genista genus; see Genisteae.
The species contain cytisine, a toxic alkaloid.
In the Spanish language the name "retama" is in common use for broom bushes in general, including but not limited to the genus Retama."
