Question: Which plant has a larger area of distribution, Dryopteris or Calpurnia?

full_context: Document 1: Clover: Clover or trefoil are common names for plants of the genus Trifolium (Latin, "tres" "three" + "folium" "leaf"), consisting of about 300 species of plants in the leguminous pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants. Clover can be evergreen. The leaves are trifoliate (rarely quatrefoiled (Four-leaf clover), cinquefoil, or septfoil), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include "Melilotus" (sweet clover) and "Medicago" (alfalfa or Calvary clover).
Document 2: Dryopteris clintoniana: Dryopteris clintoniana, commonly known as Clinton's wood fern, is a fern of hybrid origin native to the northern hemisphere. It is a fertile hexaploid, arising as a species by doubling of its chromosome number from a hybrid between "Dryopteris cristata", a tetraploid, and "Dryopteris goldiana", a diploid. It is more northern in its range than either parent species.
Document 3: Cunonia: Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species (Cunonia capensis) in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for "Cunonia capensis"). Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Document 4: Phygelius: Phygelius, common names Cape fuchsia or Cape figwort, is a genus of flowering plants in the Scrophulariaceae family, native to wet slopes and banks in southern Africa. They are evergreen shrubs often treated as perennials in colder climates. They bear many pendent tubular flowers over a long period in summer, in shades of white, yellow and red. The vague similarity of the blooms to fuchsias has led to the common name Cape fuchsia, though they are not closely related.
Document 5: Dryopteris crassirhizoma: Dryopteris crassirhizoma is a fern species in the genus "Dryopteris". It is an element (Traditional: 貫眾, Simplified: 贯众) of the Yupingfeng Asian soup formulation derivative.
Document 6: Polystichum: Polystichum is a genus of about 260 species of ferns with a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 120 species in China alone; the region from Mexico to Brazil has nearly 100 additional species; Africa (17 species), North America (15 species), and Europe (5 species) have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions (a few species grow in alpine regions).
Document 7: Dryopteris intermedia: Dryopteris intermedia, the intermediate wood fern, is an evergreen eastern North American species also occasionally found in Europe. It is a diploid species, and is the parent of several species of hybrid origin, including "Dryopteris carthusiana".
Document 8: Dryopteris goldiana: Dryopteris goldiana, commonly called Goldie's wood fern, or giant wood fern is a fern native to the eastern United States and adjacent areas of Canada, from New Brunswick to Ontario and Georgia. It is the largest native North American species of "Dryopteris" and along with ostrich fern it is one of the largest ferns in eastern North America. Specimens are known with fronds six feet (1.8 meters) tall. "D. goldiana" hybridizes with many other species of "Dryopteris" and the hybrids tend to be larger than the pure species. It was named by William Hooker in honor of its discoverer, John Goldie.
Document 9: Calpurnia (plant): Calpurnia is a genus of flowering plants within the family Fabaceae. The genus comprises shrubs or small trees in or along the margin of forests in the eastern parts of South Africa. They shed leaves in winter unless in moist areas, where they are evergreen. They make good garden plants because they are easily raised from seed, flower at two years and withstand frost.
Document 10: Prosopis caldenia: Prosopis caldenia, commonly known as the caldén, is a species of flowering tree in the pea family, Fabaceae, The tree is endemic to subtropical regions of Argentina.
Document 11: Acalypha fruticosa: Acalypha fruticosa is a species of flowering plant in the botanical family Euphorbiaceae. It occurs widely in East and southern Africa where it is eaten as a vegetable. It is also an important browse plant for sheep. In East Africa and southern Africa it is used as a medicinal plant. In northern Kenya arrow shafts and beehive lids are made from the stem. From the dried leaves a tea is made in Ethiopia.
Document 12: Caulophyllum: Caulophyllum is a small genus of perennial herbs in the family Berberidaceae. It is native to eastern Asia and eastern North America. These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer. Common names for plants in this genus include Blue Cohosh, Squaw Root, and Papoose Root. As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.
Document 13: Dryopteris cristata: Dryopteris cristata is a species of fern native to wetlands throughout the Northern Hemisphere. It is known as crested wood fern or crested buckler-fern. This plant is a tetraploid species of hybrid origin, one parent being "Dryopteris ludoviciana" and the other being the unknown, apparently extinct species, dubbed "Dryopteris semicristata", which is also one of the presumed parents of "Dryopteris carthusiana". "D. cristata" in turn is one of the parents of "Dryopteris clintoniana", another fern of hybrid origin.
Document 14: Dryopteris: Dryopteris , commonly called wood fern, male fern (referring in particular to "Dryopteris filix-mas"), or buckler fern, is a genus of about 250 species of ferns with distribution in Eastern Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest species diversity in eastern Asia. Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales.
Document 15: Calliandra calothyrsus: Calliandra calothyrsus is a small leguminous tree or large shrub in the Fabaceae family. It is native to the tropics of Central America where its typical habitat is wet tropical forests or seasonally dry forests with a dry season of four to seven months, when it may become deciduous. This tree grows to about 6 m and has pinnate compound leaves and flowers with a boss of prominent reddish-purple stamens. It is not very drought-tolerant and the above-ground parts are short-lived but the roots regularly resprout.
