French broom Genista monspessulana, copyright Philipp Weigel.

Belongs within: Genisteae.
Contains: Cytisus.

The Genistinae are a group of mostly yellow-flowered leguminous shrubs with a Mediterranean-centred distribution, though a number of species (particularly gorse Ulex europaeus and broom Cytisus scoparius) have become naturalised in other parts of the world. The gorses of the genus Ulex are extremely spiny with leaves almost entirely absent in mature plants and shoots modified into branched thorns. The genus Stauracanthus of the Iberian Peninsula and northwestern Africa differs from Ulex in having most lateral branches opposite or subopposite rather than alternate. Members of the genus Genista are characterised by flowers with a bell-shaped calyx with the upper lip strongly two-lobed, and the style more or less abruptly bent at the tip (Hickman 1993).
