Question: Which genus has more species, Worsleya or Gordonia?

full_context: Document 1: Magnolia grandiflora: Magnolia grandiflora, commonly known as the southern magnolia or bull bay, is a tree of the family Magnoliaceae native to the southeastern United States, from coastal North Carolina to central Florida, and west to East Texas and Oklahoma. Reaching 27.5 m in height, it is a large, striking evergreen tree, with large dark green leaves up to 20 cm long and 12 cm wide, and large, white, fragrant flowers up to 30 cm in diameter. Although endemic to the lowland subtropical forests on the Gulf and south Atlantic coastal plain, magnolia grandiflora is widely cultivated in warmer areas around the world. The timber is hard and heavy, and has been used commercially to make furniture, pallets, and veneer.
Document 2: List of Rhododendron species: This List of "Rhododendron" species includes species of the genus "Rhododendron", which is in the plant family Ericaceae. Depending on the source, there are anywhere from 800 to over 1,100 wild species. The vast majority of "Rhododendron" species are native to the eastern Himalaya and southeast Tibet, along with the islands of Java, Sumatra, Borneo, New Guinea, and the Philippines. The rest are broadly spread throughout the northern hemisphere in relatively small isolated populations, including Japan, northwestern North America, the Appalachian, and the Caucasus Mountains.
Document 3: Amaryllis: Amaryllis ( ) is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, "Amaryllis belladonna", is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley to Knysna. For many years there was confusion among botanists over the generic names "Amaryllis" and "Hippeastrum", one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus "Hippeastrum", widely sold in the winter months for their ability to bloom indoors. Plants of the genus "Amaryllis" are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, "Lilium".
Document 4: Hydrangea: Hydrangea ( ; common names hydrangea or hortensia) is a genus of 70–75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea. Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Document 5: Amherstia: Amherstia nobilis (Burmese: သော်ကကြီး ] ; the Pride of Burma, in the Fabaceae family) is a tropical tree with large, showy flowers. It is the only member of the genus Amherstia. It is widely cultivated for ornament in the humid tropics, but is very rare in the wild and has only been collected from its native habitat a few times. It is native to Burma (Myanmar), hence the common name. The scientific name commemorates Lady Amherst, (as does Lady Amherst's pheasant) and also her daughter Sarah. Another common name, the Orchid Tree, is otherwise reserved for members of the genus "Bauhinia".
Document 6: Griffinia: Griffinia is a genus of Brazilian plants in the Amaryllis family, subfamily Amaryllidoideae. It includes 21 known species which are endemic to Brazil in South America. The most closely related genus to it is the monotypic "Worsleya".
Document 7: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 8: Stewartia: Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to "Camellia". Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two ("S. malacodendron, S. ovata") in southeast North America, from Virginia and Kentucky south to Florida and Louisiana.
Document 9: Griffineae: The tribe Griffineae (in the family Amaryllidaceae, subfamily Amaryllidoideae) includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus "Lycoris" are able to form flowers with such color in the whole Amaryllidaceae family. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in "Worsleya" they are sword-shaped.
Document 10: Rhododendron: Rhododendron (from Ancient Greek ῥόδον "rhódon" "rose" and δένδρον "déndron" "tree") is a genus of 1,024 species of woody plants in the heath family (Ericaceae), either evergreen or deciduous, and found mainly in Asia, although it is also widespread throughout the highlands of the Appalachian Mountains of North America. It is the national flower of Nepal. Most species have brightly coloured flowers which bloom from late winter through to early summer.
Document 11: Echinodorus grisebachii: Echinodorus grisebachii or Echinodorus amazonicus is commonly known as Amazon sword plant, although other plants are also known under this common name. The aquatic plant is cultivated for and used in ponds and artificial aquatic habitats. It is native to Cuba, Central America, and South America as far south as Brazil and Bolivia.
Document 12: Worsleya: Worsleya is a genus of Brazilian plants in the Amaryllis family, widely cultivated as an ornamental because of its showy flowers. There is only one known species, Worsleya procera, native to eastern Brazil. It is one of the largest (around 1.5 meters high) and rarest members of the subfamily Amaryllidoideae (family Amaryllidaceae).
Document 13: Egeria densa: Egeria densa, the large-flowered waterweed or Brazilian waterweed, is a species of "Egeria" native to warm temperate South America in southeastern Brazil, Argentina, and Uruguay. It is considered a problematic invasive species due to its use in home aquariums and subsequent release into non-native habitats.
Document 14: Gordonia (plant): Gordonia is a genus of flowering plants in the family Theaceae, related to "Franklinia", "Camellia" and "Stewartia". Of the roughly 40 species, all but two are native to southeast Asia in southern China, Taiwan and Indochina. The remaining species, "G. lasianthus" (Loblolly-bay), is native to southeast North America, from Virginia south to Florida and west to Louisiana; "G. fruticosa" is native to the tropical rainforests of Central and South America, from Costa Rica to Brazil.
Document 15: Lauraceae: Lauraceae are the laurel family, that includes the true laurel and its closest relatives. This family of flowering plants comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as "Sassafras", are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. "Cassytha" is a genus unique to the Lauraceae family in that it is a genus of parasitic vines.
