Question: Lodoicea and Nothofagus, are genus of what mutual species?

full_context: Document 1: Oak: An oak is a tree or shrub in the genus Quercus ( ; Latin "oak tree") of the beech family, Fagaceae. There are approximately 600 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably "Lithocarpus" (stone oaks), as well as in those of unrelated species such as "Grevillea robusta" (silky oaks) and the Casuarinaceae (she-oaks). The genus "Quercus" is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.
Document 2: Castanospermum: Castanospermum australe (Moreton Bay Chestnut or Blackbean), the only species in the genus Castanospermum, is a flowering plant in the family Fabaceae, native to the east coast of Australia in Queensland and New South Wales, and to the Pacific islands of Vanuatu, New Caledonia, and the island of New Britain (Papua New Guinea). Members of this genus accumulate iminosugars in their leaves.
Document 3: Austrocedrus: Austrocedrus is a genus of conifer belonging to the cypress family Cupressaceae. It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar. The generic name means "southern cedar".
Document 4: List of largest seeds: The largest seed in the world is the coco de mer, the seed of a palm tree. It can reach about 12 inches (30 cm) long, and weigh up to 40 pounds (18 kg). The coco de mer, a giant, dark brown seed, has been protected by the government of the Seychelles because of its rarity. The coco de mer tree can grow up to 100 feet (31 m) tall, with leaves measuring 20 ft (6 m) long and 12 feet (3.6 m) wide.
Document 5: Macadamia: Macadamia is a genus of four species of trees indigenous to Australia and constituting part of the plant family Proteaceae. They are native to north eastern New South Wales and central and south eastern Queensland. The tree is commercially important for its fruit, the macadamia nuts (or simply "macadamia"). Other names include Queensland nut, bush nut, maroochi nut, bauple nut, and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as "bauple", "gyndl", "jindilli", and "boombera". Previously, more species with disjunct distributions were named as members of this genus "Macadamia". Genetics and morphological studies more recently published in 2008 show they have separated from the genus "Macadamia", correlating less closely than thought from earlier morphological studies. The species previously named in the "Macadamia" genus may still be referred to overall by the descriptive, non-scientific name of macadamia; their disjunct distributions and current scientific names are:
Document 6: Libocedrus: Libocedrus is a genus of five species of coniferous trees in the cypress family Cupressaceae, native to New Zealand and New Caledonia. The genus is closely related to the South American genera "Pilgerodendron" and "Austrocedrus", and the New Guinean genus "Papuacedrus", both of which are included within "Libocedrus" by some botanists. These genera are rather similar to the Northern Hemisphere genera "Calocedrus" and "Thuja": in earlier days, what is now "Calocedrus" was sometimes included in "Libocedrus". They are much less closely related, as recently confirmed (Gadek et al. 2000). The generic name means "teardrop cedar", apparently referring to drops of resin.
Document 7: Dypsis lutescens: Dypsis lutescens, also known as golden cane palm, areca palm, yellow palm, or butterfly palm, is a species of flowering plant in the Arecaceae family, native to Madagascar and naturalized in the Andaman Islands, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Venezuelan Antilles.
Document 8: Lodoicea: Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It formerly also was found on the small islets of St Pierre, Chauve-Souris and Ile Ronde (Round Island), all located near Praslin, but had become extinct there for a time until recently reintroduced. The name of the genus, "Lodoicea", is derived from "Lodoicus", the Latinised form of "Louis", in honour of King Louis XV of France.
Document 9: Vallée de Mai: Vallée de Mai Nature Reserve ("May Valley") is a nature park and UNESCO World Heritage Site on the island of Praslin, Seychelles. It consists of a well-preserved palm forest, flagship species made up of the island endemic coco de mer, as well as five other endemic palms. The coco de mer ("Lodoicea maldivica"), a monocot tree in the Arecaceae (palm family), has the largest seeds (double nut seed) of any plant in the world. Also unique to the park is its wildlife, including birds such as the rare Seychelles black parrot, mammals, crustaceans, snails, and reptiles. There has been a determined effort to eliminate all the introduced exotic species of plants from the area but this has not been successful in eliminating coffee, pineapple, and ornamental palms thus far. This forest, with its primitive plant and animal species, is a relict from the time when the supercontinent of Gondwana was divided into smaller parts, leaving the Seychelles islands between the present day Madagascar and India.
Document 10: Nothofagus: Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules and pollen, with fossils extending into the late Cretaceous and occurring in Australia, New Zealand, Antarctica and South America. In the past, they were included in the family Fagaceae, but genetic tests revealed them to be genetically distinct, and they are now included in their own family, the Nothofagaceae (literally meaning "false beeches" or "bastard beeches").
Document 11: Fuscospora alessandri: Fuscospora alessandrii (ruil) is a species of plant in the family Nothofagaceae, commonly known as the southern beeches. It is endemic to Chile, occurring chiefly in the Chilean matorral ecoregion. It is threatened by habitat loss. The species is protected within Los Ruiles National Reserve. It was known as "Nothofagus alessandrii" prior to 2013.
Document 12: Howea: Howea is a genus of two palms, "H. belmoreana" and "H. forsteriana", both endemic to Lord Howe Island, Australia. "H. forsteriana" in particular is commonly grown as an indoor plant in the Northern Hemisphere, and the two species form the mainstay of the island's palm seed industry and more importantly its trade in newly germinated seedlings. The palms are also cultivated on Norfolk Island, where seeds are produced for export.
Document 13: Eucalyptus: Eucalyptus L'Héritier 1789 is a diverse genus of flowering trees and shrubs (including a distinct group with a multiple-stem mallee growth habit) in the myrtle family, Myrtaceae. Members of the genus dominate the tree flora of Australia, and include "Eucalyptus regnans", the tallest known flowering plant on Earth. There are more than 700 species of eucalyptus and most are native to Australia; a very small number are found in adjacent areas of New Guinea and Indonesia. One species, "Eucalyptus deglupta," ranges as far north as the Philippines. Of the 15 species found outside Australia, just nine are exclusively non-Australian. Species of eucalyptus are cultivated widely in the tropical and temperate world, including the Americas, Europe, Africa, the Mediterranean Basin, the Middle East, China, and the Indian subcontinent. However, the range over which many eucalypts can be planted in the temperate zone is constrained by their limited cold tolerance. Australia is covered by 92000000 ha of eucalypt forest, comprising three quarters of the area covered by native forest.
Document 14: Roystonea: Roystonea is a genus of eleven species of monoecious palms, native to the Caribbean Islands, and the adjacent coasts of Florida and Central and northern South America. Commonly known as the royal palms, the genus was named for Roy Stone, a U.S. Army engineer. It contains some of the most recognizable and commonly cultivated palms in tropical and subtropical regions.
Document 15: Roystonea regia: Roystonea regia, commonly known as the Cuban royal palm or the Florida royal palm is a species of palm which is native to Mexico and parts of Central America and the Caribbean. A large and attractive palm, it has been planted throughout the tropics and subtropics as an ornamental tree. Although it is sometimes called "R. elata", the conserved name "R. regia" is now the correct name for the species. Populations in Cuba and Florida were long seen as separate species, but are now considered to belong to a single species.
