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.
There are over 190 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in)
Bupleurum is a large genus of annual or perennial herbs or woody shrubs, with about 190 species, belonging to the family Apiaceae. The full size of its species may vary between a few cm to up to 3 m high. Their compound umbels of small flowers are adorned with bracteoles that are sometimes large and may play a role in attracting pollinators. Rare among the Apiaceae are the simple leaves, bracts, and bracteoles. The genus is almost exclusively native in the Old World Northern Hemisphere, with one species native to North America and one species native to southern Africa.
Trigonella is a genus from the family Fabaceae. The best known member is the herb fenugreek. Members of the genus occur naturally in the Canary Islands, southern Europe, non‑tropical Africa, western and central Asia, the Indian subcontinent, and Australia.
Arenaria is a genus of flowering plants, within the family Caryophyllaceae.
Jacobaea is a genus of flowering plants in the tribe Senecioneae and the family Asteraceae. Its members used to be placed in the genus Senecio, but have been separated into the segregate genus Jacobaea on the basis of molecular phylogenetics in order to maintain genera that are monophyletic.
Valerianella is a genus of plant in family Caprifoliaceae. Many plants of this genus are known by the common name corn salad or cornsalad, although that name most often refers to Valerianella locusta.
Seseli is a genus of herbaceous perennial plants in the family Apiaceae. They are sometimes woody at base with a conic taproot. Leaf blades are 1–3-pinnate or pinnately decompound. Umbels are compound, with bracts few or absent. Petals are white or yellow, and the fruit ovoid or ellipsoid.
Eremogone is a genus of flowering plants in the family Caryophyllaceae, native to western North America, northern Asia, eastern Europe and northeastern Africa. Attempts to resolve taxonomic relationships within the Caryophyllaceae have resulted in the enlargement of Eremogone with species from other genera.
