Stenocarpus is a genus of about 22 species of flowering plants in the family Proteaceae. They are trees or shrubs with variably-shaped leaves, zygomorphic, bisexual flowers, the floral tube opening on the lower side before separating into four parts, followed by fruit that is usually a narrow oblong or cylindrical follicle.
Plants in the genus Stenocarpus are trees or shrubs with leaves that may be simple, compound or lobed, depending on the species. The flowers are arranged in umbels or racemes at or near the ends of branches and are zygomorphic and bisexual. Four tepals form a flower tube that opens on the lower side at first before separating into four with a spherical end, there are four sessile anthers, the single carpel is stalked and the pollen presenter is an oblique, flattened disc. The fruit is a follicle that usually opens by splitting down one side and contains up to fifty seeds. [2] [3] [4] [5]
The genus Stenocarpus was first formally described in 1810 by Robert Brown in the Transactions of the Linnean Society of London . [6] [7] The name Stenocarpus means "narrow fruit", referring to the long follicles of most species.
The following is a list of Stenocarpus species accepted by Plants of the World Online as at September 2021: [8]
Twelve species of Stenocarpus are endemic to New Caledonia. Of the ten species found in Australia, eight are endemic, occurring in New South Wales, Queensland, the Northern Territory and Western Australia. A further two species, S. moorei and S. sinuatus also occur in New Guinea and the Aru Islands. [2] [8] [9] [10]
Grevillea, commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds.
Flindersia is a genus of 17 species of small to large trees in the family Rutaceae. They have simple or pinnate leaves, flowers arranged in panicles at or near the ends of branchlets and fruit that is a woody capsule containing winged seeds. They grow naturally in Australia, the Moluccas, New Guinea and New Caledonia.
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.
Medicosma is a genus of shrubs and trees in the family Rutaceae, all native to New Guinea, Australia or New Caledonia. They usually have simple leaves arranged in opposite pairs, flowers arranged in cymes with four sepals, four petals and eight stamens. The fruit is a follicle fused at the base in groups of up to four, each containing one or two brown or black seeds.
Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They are endemic to 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.
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.
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.
Gmelina is a genus of plants in the family Lamiaceae. It consists of about 35 species in Australia, New Guinea, New Caledonia, Southeast Asia, India and a few in Africa. Some species such as G. arborea have been planted and/or become naturalised in India, Africa and Australia. It was named by Carl Linnaeus in honour of botanist Johann Georg Gmelin.
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.
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.
Stenocarpus sinuatus, known as the firewheel tree, is an Australian rainforest tree in the family Proteaceae. The range of natural distribution is in various rainforest types from the Nambucca River in New South Wales to the Atherton Tableland in tropical Queensland. Stenocarpus sinuatus is widely planted as an ornamental tree in other parts of Australia and in different parts of the world.
Stenocarpus cryptocarpus, commonly known as the giant-leaved stenocarpus, is a species of flowering plant in the family Proteaceae and is endemic to north Queensland. It is a tree with buttress roots at the base, simple, mostly elliptical adult leaves, groups of cream-coloured flowers and narrow oblong follicles.
Stenocarpus umbelliferus is a species of flowering plant in the family Proteaceae. It is endemic to New Caledonia. It has a prostrate or upright habit, growing up to 5 metres in height. Stems are flattened when young, later becoming rounded. The leaves are thick and leathery with a slightly wavy margin. These may be ovate, elliptic, lanceolate or spathulate in shape with petioles that are 3 to 12 mm long. White, cream or pale yellow flowers occur in groups of 3 to 8 per umbel. These are followed by dark-coloured glabrous follicles that are 25 to 80 mm long and 3 to 5 mm wide.
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.
Dubouzetia is a genus of about eleven species known to science, growing from shrubs up to large trees, in Papuasia and Australasia and constituting part of the plant family Elaeocarpaceae.
Stenocarpus verticis is a species of flowering plant in the family Proteaceae and is endemic to northern Australia. It is a tree with elliptic or lance-shaped adult leaves and groups of cream-coloured flowers covered with woolly, rust-coloured or grey hairs.
Stenocarpus davallioides, commonly known as the fern-leaved stenocarpus, is a species of flowering plant in the family Proteaceae and is endemic to north Queensland. It is a tree with simple or pinnate adult leaves, groups of creamy-green flowers and narrow oblong follicles.
Don Foreman was an Australian botanist who worked on the Monimiaceae and Proteaceae of Australia. He also helped with the editing of selected Flora of Victoria and Flora of Australia Volumes.
Buckinghamia ferruginiflora, also known as Noah's oak or spotted oak, is a species of rainforest tree in the protea family, one of two in the genus that is endemic to the Wet Tropics of Queensland, north-eastern Australia. Although the tree's differences from its congener had been known since the 1970s, it was only formally described by Donald Foreman and Bernard Hyland in 1988 in the journal Muelleria.
