Lepiderema is a genus of eight species of trees in the lychee family Sapindaceae native to New Guinea (2 species) and eastern Australia (6 species), plus one more from Queensland that is yet to be formally described. The type species is Lepiderema papuana . [1] [2] [3] [4]
Plants in this genus are shrubs or small trees that are usually monoecious, i.e. flowers are either male or female, but both will be produced by an individual plant. The leaves are alternate and compound, with an even number of opposite or sub-opposite leaflets that may have smooth or toothed edges. The petiolules (the stalks of the leaflets) are usually short and pulvinate. Inflorescences may be racemes or panicles, produced in the leaf axils or from the branches on old wood. Flowers are regular and 5-merous with 6–8 stamens, ovaries are 3-locular with one ovule per locule. The fruit are 3-locular capsules, glabrous, dehiscent, becoming woody. Seeds ellipsoid, one per locule, either fully or partly enclosed in an aril. [4] [5] [6]
The genus was erected in 1879 by the Bavarian botanist Ludwig Adolph Timotheus Radlkofer to accommodate the newly described plant Lepiderema papuana. The genus name Lepidorema is from the Ancient Greek words lepís meaning a scale or flake, and erêmos meaning "bereft of" or without. It refers to the scale-less petals. [3]
Plants in this genus inhabit rainforest of New Guinea and eastern Australia. The type species P. papuana is known from a single collection in Western New Guinea, likewise P. melanorrhachis is known from only one collection in Papua New Guinea. All other species are found in Queensland, with one – P. pulchella – extending into the northeastern part of New South Wales. [3] [4]
As of 24 April 2024 [update] , there are 8 species formally recognised, as follows: [1] [2] [3] [6]
In addition to the above, the following name is awaiting formal publication: [1] [3]
Alectryon is a genus of about 30 species of trees and shrubs from the family Sapindaceae. They grow naturally across Australasia, Papuasia, Melanesia, western Polynesia, east Malesia and Southeast Asia, including across mainland Australia, especially diverse in eastern Queensland and New South Wales, the Torres Strait Islands, New Guinea, the Solomon Islands, New Caledonia, New Zealand, Vanuatu, Fiji, Samoa, Hawaii, Indonesia and the Philippines. They grow in a wide variety of natural habitats, from rainforests, gallery forests and coastal forests to arid savannas and heaths.
Cupaniopsis is a genus of about 67 species of trees and shrubs of the soapberry family, Sapindaceae. They grow naturally in New Guinea, New Caledonia, Australia, Torres Strait Islands, Fiji, Samoa, Sulawesi, Micronesia. Many species have been threatened with extinction globally or nationally, with official recognition by the International Union for Conservation of Nature (IUCN) and several national and state governments.
Harpullia is a genus of about 27 species of small to medium-sized rainforest trees from the family Sapindaceae. They have a wide distribution ranging from India eastwards through Malesia, Papuasia and Australasia to the Pacific Islands. They grow naturally usually in or on the margins of rainforests or associated vegetation.
Jagera is a genus of 4 species of forest trees known to science, constituting part of the plant family Sapindaceae.
Diploglottis is a genus of 11 species in the lychee and maple family Sapindaceae. Most species only occur in the Wet Tropics bioregion of Queensland, but all species except one are endemic to eastern Australia, with the exception being D. diphyllostegia, which also occurs in New Guinea. They are commonly called tamarinds, for example northern tamarind, Babinda tamarind and Bernie's tamarind, however they are not closely related to the true tamarind from the family Fabaceae.
Toechima is a genus of small to medium-sized trees in the plant family Sapindaceae. The species are native to New South Wales, the Northern Territory and Queensland in Australia as well as New Guinea.
Arytera is a genus of about twenty–eight species known to science, of trees and shrubs and constituting part of the plant family Sapindaceae. They grow naturally in New Guinea, Indonesia, New Caledonia, Australia, the Solomon Islands, Vanuatu, Fiji, Samoa, Tonga; and the most widespread species and type species A. littoralis grows throughout Malesia and across Southeast Asia, from NE. India, southern China, Borneo, Malaysia, Singapore, Indonesia and the Philippines to as far east as New Guinea and the Solomon Islands.
Atalaya is a genus of eighteen species of trees and shrubs of the plant family Sapindaceae. As of 2013 fourteen species grow naturally in Australia and in neighbouring New Guinea only one endemic species is known to science. Three species are known growing naturally in southern Africa, including two species endemic to South Africa and one species in South Africa, Eswatini and Mozambique.
Elattostachys is a genus of about 21 species of trees known to science, constituting part of the plant family Sapindaceae.
Mischocarpus is a genus of about nineteen species of trees known to science, constituting part of the plant family Sapindaceae. They grow naturally from Australia and New Guinea, though Malesia as far north as the Philippines, through SE. Asia, Indo-China and S. China, to India at their farthest west. The eleven Australian species known to science grow naturally in the rainforests of the eastern coastal zone of New South Wales and Queensland, from Newcastle northwards through to north-eastern Queensland and Cape York Peninsula.
Lepiderema pulchella, commonly known as fine-leaved tuckeroo, is a species of flowering plant in the family Sapindaceae and is endemic to coastal eastern Australia. It is a tree with pinnate, glossy light green leaves with four to fourteen leaflets, panicles of yellow-orange flowers and brown, spherical to three-lobed fruit.
Mischarytera is a genus of rainforest trees, constituting part of the plant family Sapindaceae. Four species are known to science as of December 2013, found growing naturally in eastern Queensland, Australia, and in New Guinea. Formerly until 1995, they had names within the genus Arytera, subgenus Mischarytera.
Rhysotoechia is a genus of plants in the soapberry family Sapindaceae which is native to parts of Malesia and Australia.
Lepidopetalum is a genus of six species of trees known to science, constituting part of the plant family Sapindaceae.
Cnesmocarpon is a genus of 4 species of rainforest trees known to science, constituting part of the plant family Sapindaceae.
Diploglottis harpullioides, commonly known as Babinda tamarind, is a rainforest tree in the lychee and maple family Sapindaceae which is found only in northeast Queensland, Australia.
Cupaniopsis flagelliformis, commonly known as brown tuckeroo or weeping flower tamarind, is a tree in the lychee, guaraná and maple family Sapindaceae which is endemic to eastern Australia. It is a small tree that inhabits drier or seasonal rainforests.
Diploglottis bernieana, commonly known as Bernie's tamarind or large leaf tamarind, is a plant in the maple and lychee family Sapindaceae. It was first described in 1987 by the Australian botanist Sally T. Reynolds and is found only the Wet Tropics region of northeastern Queensland, Australia.
Lepiderema sericolignis, commonly known as silkwood, is a plant in the maple and lychee family Sapindaceae found only in the Wet Tropics bioregion of Queensland, Australia.
Lepiderema papuana is a tree in the lychee family Sapindaceae found only in Western New Guinea. It is the type species for Lepiderema, and is known from only a single collection.
