Question:  Which species, Cardwellia or Ochagavia, is native to South America?

full_context: Document 1: Elaeocarpus eumundi: Elaeocarpus eumundi is a mid-sized rainforest tree of eastern Australia. It grows from the Richmond River, New South Wales to the McIllwraith Range at Cape York Peninsula. This tree is considered rare in New South Wales. Commonly known as the Eumundi Quandong, or Smooth Leafed Quandong. "Elaeocarpus eumundi" grows on warm temperate, riverine, and tropical rainforests.
Document 2: Puya venusta: Puya venusta is a species in the Bromeliaceae family. This species is a rare plant found in certain portions of Chile including Punta Teatinos and Cerro La Campana. In La Campana National Park "P. venusta" is associated with the endangered Chilean Wine Palm, "Jubaea chilensis", a palm that prehistorically had a significantly wider distribution.
Document 3: 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 4: Ceratopetalum apetalum: Ceratopetalum apetalum, the coachwood, scented satinwood or tarwood, is a medium-sized hardwood tree, straight-growing with smooth, fragrant, greyish bark. It is native to eastern Australia in the central and northern coastal rainforests of New South Wales and southern Queensland, where is often found on poorer quality soils in gullies and creeks and often occurs in almost pure stands. "C. apetalum" is one of 8 species of "Ceratopetalum" occurring in eastern Australia, New Guinea, New Britain and various islands in the same region.
Document 5: Ochagavia: Ochagavia is a genus of the botanical family Bromeliaceae, subfamily Bromelioideae. The genus is named for Sylvestris Ochagavia, Chilean minister of education. Endemic to southern and central Chile (including the Juan Fernández Islands), this genus is represented by four accepted species.
Document 6: Brocchinia: Brocchinia is a genus of the botanical family Bromeliaceae, subfamily Pitcairnioideae. However, a recent DNA study suggests the breakup of the Pitcairnioideae subfamily into 6 new subfamilies and "Brocchinia" would be the sole genus of new subfamily Brocchinioideae (family Bromeliaceae). The genus is named for Giovanni Battista Brocchi, Italian naturalist (1772–1826). "Brocchinia" species are native primarily to the ancient Guayana Shield in southern Venezuela and Guyana, with some species extending into Colombia and northern Brazil. Its species are generally restricted to areas of sand and sandstone of the Roraima Formation; a few occur on granite.
Document 7: 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 8: Cardwellia: Cardwellia is a genus of a sole described species of large trees, constituting a part of the plant family Proteaceae. The species Cardwellia sublimis (northern silky oak) grows naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia. Other common names include bull oak, golden spanglewood, lacewood, oak and oongaary. The compound leaves have up to 17 leaflets. It produces white inflorescences followed by woody fruits which are prominently displayed outside the canopy.
Document 9: Kageneckia oblonga: Kageneckia oblonga (also known as Bollen) is a species of plant in the Rosaceae family. It is endemic to Chile. "K. oblonga" is an evergreen tree. It grows from Coquimbo to Malleco (29 to 38°S). Example occurrences are found specifically found in central Chile within the La Campana National Park and Cerro La Campana forest areas. In these areas the endangered Chilean Wine Palm, "Jubaea chilensis" is an associated tree species.
Document 10: 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 11: Ochna: Ochna is a genus comprising 86 species of evergreen trees, shrubs and shrublets belonging to the family "Ochnaceae". These species are native to tropical woodlands of Africa, the Mascarenes and Asia. Species of this genus are usually called Ochnas, Bird's-eye bushes or Mickey-mouse plants, a name derived from the shape of the drupelet fruit. The name of this genus comes from the Greek word "Ochne", used by Homer and meaning "wild pear", as the leaves are similar in appearance. Some species, especially "Ochna serrulata" (bird's eye plant), are widely cultivated as decorative plants.
Document 12: 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.
Document 13: Buckinghamia: Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They grow naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, "B. celsissima", is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, "B. ferruginiflora", was only recently described in 1988.
Document 14: Pitcairnioideae: The Pitcairnioideae comprise the terrestrial subfamily of the bromeliads (Bromeliaceae) with over 1000 species in 16 genera. Unlike the many epiphytes and lithophytes which make up the rest of the family, with a few exceptions, all of the members of this subfamily are either terrestrial or saxicolous. Common to arid and high-altitude regions, this subfamily is considered to have the most ancient lineage, more closely resembling its grassy relatives than the exotic novelties represented in the other two subfamilies. The commonly cultivated genera from this group include "Dyckia", "Hechtia", "Pitcairnia", and "Puya".
Document 15: Puya coquimbensis: Puya coquimbensis is a species in the Bromeliaceae family. This species is a rare plant found in certain portions of Chile including Punta Teatinos and Cerro La Campana. In La Campana National Park "P.coquimbensis" is associated with the endangered Chilean Wine Palm, "Jubaea chilensis", which palm prehistorically had a much wider distribution.
