Habit: Shrub, spiny or unarmed; generally deciduous. Stem: generally ribbed or angled, green. Leaf: generally alternate, ternately 1-compound or simple, petioled; stipules fused to leaf bases (0). Inflorescence: axillary or terminal, racemes, heads, or flowers in clusters on short-shoots. Flower: bilateral; calyx generally < corolla, 2-lipped, upper 2-lobed, lobes +- 1/2 tube, lower generally 3-toothed, < upper lobes; petals 5, generally yellow, banner generally ovate or rounded, outside generally glabrous or variously hairy, keel narrowly oblong to obtuse, +- straight abaxially, often silky-hairy; stamens 10, filaments fused; style +- abruptly bent at tip. Fruit: generally dehiscent, narrowly oblong, compressed, or curved, +- inflated; pedicel < 7 mm. Seed: 1--several-seeded, generally arilled.
Species In Genus: 90 species: Europe, western Asia, northern Africa, Canary Islands. Etymology: (Latin: from planta genista, from which English Plantagenet monarchs took their name) Note: Generic circumscription difficult, but Pardo et al. (2004 Plant Syst Evol 244:93--119) suggest recognizing Genista in broad sense (i.e., including Retama, Teline, Ulex). Many naturalized California plants are hybrids involving Genista canariensis, Genista monspessulana, and Genista stenopetala Webb & Berthel. (native of Canary Islands; not in California in pure form), although determining parentage in generally often difficult.
