Ripogonum is a genus of flowering plants confined to eastern Australia, New Zealand, and New Guinea. Until recently this genus was included in the family Smilacaceae, and earlier in the family Liliaceae, but it has now been separated as its own family Ripogonaceae.
Stenocarpus is a genus of about 25 species of woody trees or shrubs, constituting part of the plant family Proteaceae.
Weinmannia is a genus of trees and shrubs in the family Cunoniaceae. It is the largest genus of the family with about 150 species. It is also the most widespread genus, occurring in Central and South America including the Caribbean, Madagascar and surrounding islands, Malesia and the islands of the South Pacific. It is absent from mainland Africa and Australia, but some fossils have been attributed to Weinmannia in Australia. Leaves are simple or pinnate, with a margin usually toothed, and interpetiolar stipules. Flowers are bisexual, white, arranged in racemes. The fruit is a capsule opening vertically from the top to the base. Seeds hairy without wings.
Meryta is a genus in the flowering plant family Araliaceae. There are 28 described species in the genus and a number of undescribed species, all small, resinous trees of the subtropical and tropical Pacific Ocean, characterized by huge, simple leaves and a dioecious sexual system, a unique combination in Araliaceae. Meryta has its center of diversity in New Caledonia. Phylogenetic analyses have placed Meryta as a monophyletic genus in one of the three major clades of the Araliaciae, the Polyscias-Pseudopanax group, and more specifically in the Pacific Schefflera subclade.
Barringtonia is a genus of flowering plants in the family Lecythidaceae first described as a genus with this name in 1775. It is native to Africa, southern Asia, Australia, and various islands of the Pacific and Indian Oceans. The genus name commemorates Daines Barrington.
Basselinia is a genus of flowering plant in the family Arecaceae. The entire genus is endemic to the Island of New Caledonia in the Pacific. In some molecular phylogenetic analyses, Hedyscepe from Lord Howe Island is nested in Basselinia.
Beauprea is a genus of flowering plants in the family Proteaceae. Its 13 extant species are endemic to New Caledonia, though closely related forms have been found in the fossil records of Australia and New Zealand. Its closest extant relatives are the African Protea and Faurea.
Kermadecia is a genus of flowering plants in the family Proteaceae. The genus comprises five species, all endemic to New Caledonia. Its closest relatives are Sleumerodendron and Turrillia, of which the species have once been placed in Kermadecia.
Pancheria is a genus of shrubs and trees in the family Cunoniaceae. It is to endemic to New Caledonia and contains 27 species. Leaves or whorled, simple or pinnate. The flowers are arranged in capitula, fruits are follicular. The species are dioecious. The genus is well diversified on ultramafic rocks and some species are nickel hyperaccumulators. It is related to Cunonia and Weinmannia. It was named after Jean Armand Isidore Pancher.
Spiraeanthemum is a genus of trees and shrubs in the family Cunoniaceae. it includes about 19 species from Australia, New Guinea, Solomon Islands, New Caledonia, Vanuatu, Fiji and Samoa. Leaves are simple, opposite or whorled, with toothed or entire margins. Inflorescences are paniculate, flowers unisexual or hermaphrodite, and the fruits are follicular with free carpels. It belongs to the tribe Spiraeanthemeae, and now includes the species formerly placed in Acsmithia.
Xanthostemon is a genus of trees and shrubs, constituting part of the myrtle plant family Myrtaceae. This genus was first described in 1857 by German–Australian botanist Ferdinand von Mueller. According to different official sources between 46 and 51 species are known to science. They grow naturally in New Caledonia, Australia, the Solomon Islands and Malesia, including the Philippines, New Guinea and Indonesia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
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 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. Flowers are bisexual, white, red, or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Hedycarya is a genus of dioecious trees and shrubs of the family Monimiaceae. Species occur in South East Asia, New Caledonia, Australia and Polynesia including New Zealand. The genus was named and formerly described in 1776 by botanists Johann and Georg Forster in Characteres Generum Plantarum. The limit of the genus may require change as it appears paraphyletic in phylogenetic analyses, with the genera Kibaropsis and Levieria nested in it.
Virotia is a genus of six species of flowering plants in the family Proteaceae. The genus is endemic to New Caledonia with six species that were once placed in Macadamia. Its closest relatives are the Australian Athertonia and the Asian Heliciopsis. The genus is named after Robert Virot, pioneer of ecological studies in New Caledonia and author of a monograph of New Caledonian Proteaceae.
Balanophora is a genus of parasitic plants in the family Balanophoraceae found in parts of tropical and temperate Asia, including the Eastern Himalayas, Malesia region, Pacific Islands, Madagascar, and tropical Africa. There are about 20 accepted species, including the newly discovered B. coralliformis. Many species emit an odour which possibly attracts pollinators in the same way that pollinators are attracted to Rafflesia.
Schefflera umbellifera is an evergreen to semi-deciduous Southern African tree of 15-20m growing in escarpment and coastal forest in Malawi, through eastern Zimbabwe and Mozambique along the east coast to South Africa, as far south as the Garden Route. It belongs to the Araliaceae or Cabbage Tree family and is one of some 600 species in the genus Schefflera, created by J.R.Forst. & G.Forst. in 1776 to honour the 18th century German physician and botanist Johann Peter Ernst von Scheffler of Danzig, and not to be confused with writer and physician Jacob Christoph Scheffler (1698-1745) of Altdorf bei Nürnberg.
Balanophora fungosa, sometimes known as fungus root is a flowering plant in the family Balanophoraceae and occurs in South Asia, Southeast Asia, Australia and some Pacific Islands. It is an obligate parasite growing on the roots of rainforest trees. The flowering structure is shaped like a puffball but in fact consists of a globe covered with thousands of tiny female flowers. The globe is surrounded at its base by a much smaller number of male flowers. In flower, the plant emits an odour resembling that of mice.
Plagianthus is a genus of flowering plants confined to New Zealand and the Chatham Islands. The familial placement of the genus was controversial for many years, but modern genetic studies show it definitely belongs in the Malvaceae subfamily Malvoideae. The name means "slanted flowers".
Characteres generum plantarum is a 1775/1776 book by Johann Reinhold Forster and Georg Forster about the botanical discoveries they made during the second voyage of James Cook. The book, which contains 78 plates, introduced 94 binomial names from 75 genera, of which 43 are still the accepted names today.
