Are Crotalaria and Genista both types of shrubs?
Genista Genista is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including "Cytisus" and "Chamaecytisus". Brooms in other genera are sometimes considered synonymous with "Genista": "Echinospartum", "Retama", "Spartium", "Stauracanthus", and "Ulex".
Macrocarpaea The genus Macrocarpaea, with 105 species and two hybrids of 0.5 m herbs, shrubs, epiphytes and small trees to 10 m tall, is the largest genus of the tribe Helieae of the gentian family (Gentianaceae). Species of "Macrocarpaea" have diurnal and nocturnal pollinators, visited during the day by hummingbirds, insects and butterflies, and at night by bats, moths and many different kinds of insects. The common name for the genus is 'Moon-gentian'. No species are known in cultivation.
