Question: Which genus has over 750 species, Indigofera or Eriophyllum?

full_context: Document 1: Enceliopsis: Enceliopsis is a small genus of flowering plants in the daisy family. They are sometimes called sunrays. They are similar to the daisylike plants in the related genus "Encelia". These three shrubs are native to the western United States and Canada.
Document 2: Eriocaulon: Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae. The genus is widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly southern Asia and the Americas. A few species extend to temperate regions, with ca. 10 species in the United States, mostly in the southern states from California to Florida, and only two species in Canada; China has 35 species, also mostly southern. Only one species ("E. aquaticum") occurs in Europe, where it is confined to the Atlantic Ocean coasts of Scotland and Ireland; this species also occurs in eastern North America and is thought to be a relatively recent natural colonist in Europe. In the Americas, "Eriocaulon" is the only genus in its family that occurs north of Florida. They tend to be associated with wet soils, many growing in shallow water, in wetlands, or in wet savannas like flatwoods. In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses. Experiments have shown that they are weak competitors compared to many other wetland plant species. Some species can persist as buried seeds during unfavorable conditions. The scientific name is derived from Ancient Greek εριον, "erion", meaning 'wool', and καυλός, "caulos", meaning 'stalk'.
Document 3: Gaillardia aristata: Gaillardia aristata is a North American species of flowering plants in the sunflower family known by the common names common blanketflower and common gaillardia. This perennial wildflower is widespread across much of North America, from Yukon east to Québec and south as far as California, Arizona, Illinois, and Connecticut, although it may be naturalized rather than native in parts of that range. It is also naturalized in scattered locations in Europe, Australia, and South America.
Document 4: Strobilanthes: Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their 2-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.
Document 5: Indigofera tinctoria: Indigofera tinctoria, also called true indigo, is a species of plant from the bean family that was one of the original sources of indigo dye. It has been naturalized to tropical and temperate Asia, as well as parts of Africa, but its native habitat is unknown since it has been in cultivation worldwide for many centuries. Today most dye is synthetic, but natural dye from "I. tinctoria" is still available, marketed as natural coloring where it is known as tarum in Indonesia and nila in Malaysia. In Iran and areas of the former Soviet Union it is known as basma. The plant is also widely grown as a soil-improving groundcover.
Document 6: Baptisia: Baptisia (wild indigo, false indigo) is a genus in the legume family, Fabaceae. They are flowering herbaceous perennial plants with pea-like flowers, followed by pods, which are sometimes inflated. They are native to woodland and grassland in eastern and southern North America. The species most commonly found in cultivation is "B. australis".
Document 7: Helianthus californicus: Helianthus californicus is a North American species of sunflower known by the common name California sunflower. It is native to California in the United States and Baja California in Mexico, where it grows in many types of habitats.
Document 8: Erigeron inornatus: Erigeron inornatus is a North American species of flowering plant in the daisy family known by the common name California rayless daisy, California rayless fleabane, rayless fleabane, Lava rayless fleabane
Document 9: Bauhinia: Bauhinia is a genus of more than 500 species of flowering plants in the subfamily Cercidoideae of the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers, Swiss-French botanists.
Document 10: 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 11: Indigofera: Indigofera is a large genus of over 750 species of flowering plants belonging to the family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.
Document 12: Eriophyllum: Eriophyllum, commonly known as the woolly sunflower, is a North American genus of plants in the sunflower family. The genus is native to western North America (USA, Canada, northwestern Mexico), with a concentration of narrow endemics in California.
Document 13: Indigofera australis: Indigofera australis, known as Australian Indigo, is an attractive species of leguminous shrub in the genus "Indigofera" (Fabaceae family). The genus name ""Indigofera"" is Neo-Latin for "bearing Indigo" (Indigo is a purple dye originally obtained from some "Indigofera" species), while "australis" from the Latin, means "southern", referring to the geographical distribution of the species.
Document 14: Eriogonum: Eriogonum is the scientific name for a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat ("Eriogonum fasciculatum").
Document 15: Fabaceae: The Fabaceae or Papilionoideae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulated leaves. Many legumes have characteristics of flowers and fruits. The family is widely distributed, and is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with about 751 genera and some 19,000 known species. The five largest of the genera are "Astragalus" (over 3,000 species), "Acacia" (over 1000 species), "Indigofera" (around 700 species), "Crotalaria" (around 700 species) and "Mimosa" (around 500 species), which constitute about a quarter of all legume species. The ca. 19,000 known legume species amount to about 7% of flowering plant species. Fabaceae is the most common family found in tropical rainforests and in dry forests in the Americas and Africa.
