<span class="mw-page-title-main">Malesia</span> Biogeographical region in Southeast Asia

Malesia is a biogeographical region straddling the Equator and the boundaries of the Indomalayan and Australasian realms. It is a phytogeographical floristic region in the Paleotropical kingdom. It was first recognized as a distinct region in 1857 by Heinrich Zollinger, a Swiss botanist and explorer. The precise boundaries used to define Malesia vary. The broadly defined area used in Flora Malesiana consists of the countries of Malaysia, Singapore, Indonesia, Brunei, the Philippines, Timor-Leste and Papua New Guinea. The original definition by the World Geographical Scheme for Recording Plant Distributions (WGSRPD) covered a similar area, but New Guinea and some offshore islands were split off as Papuasia in its 2001 version.

<i>Intsia bijuga</i> Species of tree in the family Fabaceae

Intsia bijuga, commonly known as Borneo teak, ipil, Johnstone River teak, and kwila, amongst many other names, is a species of tree in the flowering plant family Fabaceae, native to coastal areas from east Africa, through India and Southeast Asia to Australia and the western Pacific. It has significant importance to indigenous cultures in many parts of its range, but is also threatened by illegal logging due to its high quality timber. It is most commonly found in tropical coastal forests.

<i>Atalaya</i> (plant) Genus of plants

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.

<i>Verticordia</i> Genus of flowering plants

Verticordia is a genus of more than 100 species of plants commonly known as featherflowers, in the myrtle family, Myrtaceae. They range in form from very small shrubs such as V. verticordina to trees like V. cunninghamii, some spindly, others dense and bushy, but the majority are woody shrubs up to 2.0 m (7 ft) tall. The flowers are variously described as "feathery", "woolly" or "hairy" and are found in most colours except blue. They often appear to be in rounded groups or spikes but in fact are always single, each flower borne on a separate stalk in a leaf axil. Each flower has five sepals and five petals all of a similar size with the sepals often having feathery or hairy lobes. There are usually ten stamens alternating with variously shaped staminodes. The style is simple, usually not extending beyond the petals and often has hairs near the tip. All but two species are found in Southwest Australia, the other two occurring in the Northern Territory.

<span class="mw-page-title-main">Flora of Australia</span> Plant species of Australia

The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.

<i>Antidesma ghaesembilla</i> Species of plant in Phyllanthaceae family

Antidesma ghaesembilla is a species of plant in the Phyllanthaceae family. It is native to an area from northern Australia to the Philippines, China, and west to India. The shrub or tree usually grows in moist soils in plant communities ranging from savannah to gallery forest to closed forest. It is associated with a number of species of fungus, insects and animals, including emus. Amongst the Mangarrayi and Yangman people of north Australia, the sweet ripe fruit of the tree are much appreciated and linked to the build-up season and to the koel. As well as food, the plant is used as a calendar-plant, for dyeing, in traditional medicine, in religious/magical practices, as fuel, and as an insecticide.
