Octomeles sumatrana Miq. | |
Octomeles [2] is a monotypic genus of plant in family Tetramelaceae. The sole species is Octomeles sumatrana, [3] [4] sometimes written O. sumatranum. [5]
Octomeles sumatrana, commonly called Benuang, or Ilimo, is found in Brunei, Indonesia, Malaysia, Papua New Guinea, the Philippines, and the Solomon Islands. It and Tetrameles nudiflora are the only two species in the family Tetramelaceae. They were previously classified in the Datiscaceae but found genetically to not form a natural clade with the other members of that family. [6]
The tree is dioecious and large: reaching up to 75 m (246 ft) in height and up to thirteen feet (four meters) in diameter above the buttresses. [7] A pioneer species, it regenerates quickly in disturbed habitats such as logged forest and previously cultivated land. It has been known to grow as much as 82 feet (25 meters) in height and up to 18.5 inches (0.47 meters) diameter at breast height (DBH) in just four years, [8] [9] equivalent to annual rings 2.3 inches (six centimeters) wide. Also, like other pioneer species, it is relatively short lived; even the emergent titans rarely exceeding 85 years of age. [10] It also has noteworthy buttresses; up to 19.5 feet (six meters) high by up to forty-nine feet (15 meters) in length. [11] On Bougainville the buttresses take a different form; higher and narrower, up to 52 feet (16 meters) in height while only 18 feet (5.5 meters) in length. [12]
Agathis robusta, commonly known as Dundathu pine, kauri pine, Queensland kauri (pine), Australian kauri (pine) or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. Although some common names use the word 'pine' it is not a true pine, having leaves rather than needles. It has a disjunct distribution, occurring in Papua New Guinea and two locations in Queensland, Australia.
Intsia is a genus of flowering plants in the family Fabaceae. It includes two species which range from eastern Africa and Madagascar to India, Indochina, Malaysia, Papua New Guinea, northern Australia, and the south Pacific. They are trees which grow up to 40 (–45) meters tall, often buttressed, evergreen and unarmed. Typical habitat is humid tropical lowland forest including coastal forest on sand, rain forest, mangrove fringes and tidal river mouths, and occasionally inland on hills.
Brachylaena huillensis, the muhuhu, is a species of flowering plant in the family Asteraceae. It is found in the montane forests of Angola, Kenya, Mozambique, South Africa, Tanzania, Uganda, and Zimbabwe. With a height of up to 131 feet it is, with Vernonia arborea, a candidate for the tallest of all composites, and at up to 60 centimeters also the most massive.
Aglaia spectabilis is a species of tree in the family Meliaceae, found from the Santa Cruz Islands in the southwest Pacific to Queensland (Australia), Southeast Asia, Yunnan (Zhōngguó/China) and the Indian subcontinent. It grows from a 1m shrub to an emergent 40m tall tree, depending on the habitat. Its wood is commercially exploited as timber, but otherwise is of poor quality with limited use. The fruit are eaten, and used in folk medicine. The seeds are large in comparison to other plants, and a major source of dispersal of the species are hornbills eating the fruit, flying away from the tree and regurgitating the seeds.It is also found in Assam, India
Shorea leprosula is a species of tree in the family Dipterocarpaceae. It is native to Sumatra, Borneo, Peninsular Malaysia, Java, and Thailand.
Tetrameles is a genus of flowering plants in the family Tetramelaceae with one species, Tetrameles nudiflora. It grows as a large deciduous tree and is found across southern Asia from India through southeast Asia, Malesia, and into northern Australia. The largest tree in Thailand is of this species, and was measured on February 29, 2016 by dendrologist Marc Meyer using a Nikon Forestry 500/pro laser. Its height is exactly 64.20 meters with a girth of exactly 24.20 meters.
Castanopsis acuminatissima is an evergreen tree native to Southeast Asia and New Guinea. It is known by a variety of common names over its range, including white oak, New Guinea oak, Papua New Guinea oak, ki riung, ko-duai, ko-soi, ko-mat, meranak, and riung anak.
Dendrocnide peltata, commonly known simply as the stinging tree or jelaton, is a large tree in the nettle family Urticaceae. With the other species of the genus Dendrocnide, it is known for the stinging hairs which cover the whole plant and cause severe pain when touched. The Latin specific epithet peltata means "shield shaped", referring to the shape of the leaves.
Cratoxylum sumatranum is a species of flowering plant in the Hypericaceae family. Found in Southeast Asia, it grows up to 51 m (167 ft) tall and is harvested locally for timber and fuel.
Gymnostoma is a genus of about eighteen species of trees and shrubs, constituting one of the four genera of the plant family Casuarinaceae. The species grow naturally in the tropics, including at high elevations having temperate climates, in forests in the region of the western Pacific Ocean and Malesia. In New Caledonia, published botanical science describes eight species found growing naturally, which botanists have not found anywhere else (endemics). Other species are native to Borneo, Sumatra, Maluku, and New Guinea, and one endemic species each in Fiji and the Wet Tropics of Queensland, Australia.
Donella lanceolata is a plant species in the family Sapotaceae. It is a tree growing up to 30 metres (100 ft) tall, with a trunk diameter of up to 40 cm (16 in). The bark is grey to dark brown. Inflorescences bear up to 45 flowers. The fruit are brownish to purplish black, ripening yellow, round, up to 4 cm (2 in) in diameter. Its habitat is lowland forests from sea level to 700 metres (2,300 ft) altitude. Its natural range is Madagascar, India, Sri Lanka, Thailand, Cambodia, Laos, Vietnam, Malaysia, Brunei, Indonesia, the Philippines, Papua New Guinea, the Solomon Islands and Queensland.
Toona sureni is a species of tree in the mahogany family. It is native to South Asia, Indochina, Malesia, China, and Papua New Guinea. It is commonly known as the suren toon, surian, limpaga, iron redwood or the red cedar. It is also known as the Indonesian mahogany or the Vietnamese mahogany. The species is a valuable timber tree.
Diospyros sumatrana is a tree in the family Ebenaceae. The specific epithet refers to Sumatra.
The Vogelkop–Aru lowland rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the peninsular lowlands of western New Guinea, along with the Aru Islands and other nearby islands.
Palaquium galactoxylum, commonly known as Cairns pencil cedar, Daintree maple or red silkwood, is a species of plants in the star apple family Sapotaceae which is endemic to rainforests of New Guinea and northern Australia. It can produce spectacularly large buttress roots.
Spathiostemon javensis is a plant that can grow as a shrub or a tree in the tribe Acalypheae of the family Euphorbiaceae. It is native to the region from the Bismarck Archipelago to New Guinea, Wallacea and into Southeast Asia. It is often common in the understorey of forests. The wood is used in constructions.
Hopea novoguineensis is a rainforest tree species in the Dipterocarpaceae family. It is found in New Guinea and on Halmahera, Maluku Province, Indonesia. The tree produces good timber.
Campnosperma brevipetiolatum is a species of tree in the Anacardiaceae family. It is native to an area in the west Pacific and Malesia from the Santa Cruz Islands to the Caroline Islands and Sulawesi. It is commonly used for its timber, including for canoe making, but also for oil-production and medicine. It has been used as an indicator species to identify 19th century sites of indigenous occupation in the Solomon Islands.
Chisocheton lasiocarpus is a species of tree in the genus Chisocheton of the Mahogany Family (Meliaceae). It is a sparsely branched, slightly buttressed, somewhat stout mesocaul or rather slender pachycaul tree of the western New Guinea rainforest rising to 110 feet in height, and possibly the only such tree with a weeping habit, the huge terminal rosettes of five foot long pinnate leaves of the lower branches facing down toward the earth. Like all Chisochetons, C. lasiocarpus has indeterminate leaves with a tiny circinate bud at the tip of each leaf which produces a new pair of leaflets every few weeks or months over a period of several years, each leaf eventually reaching five feet in length. There are 9 to 11 pairs of leaflets at a time. Each leaflet can be up to 18 inches long by up to nine inches in width. The flowers are white or pink, tubular, about a half inch long with 4 or 5 petals and 7 or 8 stamens. The tree is "myrmecophilous". C. lasiocarpus is a highly variable species.
Nothofagus carrii is a species of tree in the family Nothofagaceae. It is endemic to New Guinea.
