Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is smooth, fibrous or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Australia is covered by 92,000,000 hectares of eucalypt forest, comprising three quarters of the area covered by native forest.
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally-occurring resins.
Freshwater is a national park in Queensland, Australia, 34 km north of Brisbane. The park is west of Redcliffe, near Deception Bay, within Caboolture Shire.
Nyssa sylvatica, commonly known as Tupelo, Black gum, sour gum, is a medium-sized deciduous tree native to eastern North America from the coastal Northeast USA and southern Ontario south to central Florida and eastern Texas, as well as Mexico.
Corymbia is a genus of about 113 species of tree that were classified as Eucalyptus species until the mid-1990s. It includes the bloodwoods, ghost gums and spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse genus Eucalyptus since 1867. Molecular research in the 1990s, however, showed that they, along with the rest of the section Corymbia, are more closely related to Angophora than to Eucalyptus, and are probably best regarded as a separate genus. All three genera—Angophora, Corymbia and Eucalyptus—are closely related, often difficult to tell apart, and are still commonly and correctly referred to as "eucalypts". Groups of naturalists and conservationists do not recognise the genus Corymbia and still categorise its species within Eucalyptus.
Corymbia ficifolia, commonly known as the red flowering gum, Albany red flowering gum and the Albany redgum, is one of the most commonly planted ornamental trees in the broader eucalyptus family. The species was previously known as Eucalyptus ficifolia until re-classified in 1995.
Gum tree is a common name for smooth-barked trees and shrubs in three closely related genera of Eucalypt:
Gum arabic, also known as acacia gum, arabic gum, gum acacia, acacia, Senegal gum and Indian gum, and by other names, is a natural gum consisting of the hardened sap of various species of the acacia tree. Gum arabic is collected from acacia species, predominantly Acacia senegal and Vachellia (Acacia) seyal. The term "gum arabic" does not indicate a particular botanical source. In a few cases so‐called "gum arabic" may not even have been collected from Acacia species, but may originate from Combretum, Albizia or some other genus. The gum is harvested commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia—though it is historically cultivated in Arabia and West Asia.
Agathis, commonly known as kauri or dammar, is a genus of 22 species of evergreen tree. The genus is part of the ancient Araucariaceae family of conifers, a group once widespread during the Jurassic and Cretaceous periods, but now largely restricted to the Southern Hemisphere except for a number of extant Malesian Agathis.
American sweetgum, also known as American storax, hazel pine, bilsted, redgum, satin-walnut, star-leaved gum, alligatorwood, or simply sweetgum, is a deciduous tree in the genus Liquidambar native to warm temperate areas of eastern North America and tropical montane regions of Mexico and Central America. Sweet gum is one of the main valuable forest trees in the southeastern United States, and is a popular ornamental tree in temperate climates. It is recognizable by the combination of its five-pointed star-shaped leaves and its hard, spiked fruits. It is currently classified in the plant family Altingiaceae, but was formerly considered a member of the Hamamelidaceae.
Eucalyptus camaldulensis, commonly known as the river red gum, is a tree that is endemic to Australia. It has smooth white or cream-coloured bark, lance-shaped or curved adult leaves, flower buds in groups of seven or nine, white flowers and hemispherical fruit with the valves extending beyond the rim. A familiar and iconic tree, it is seen along many watercourses across inland Australia, providing shade in the extreme temperatures of central Australia.
Senegalia senegal is a small thorny deciduous tree from the genus Senegalia, which is known by several common names, including Gum acacia, Gum arabic tree, Sudan gum and Sudan gum arabic. In parts of India, it is known as Kher or Khor. It is native to semi-desert regions of Sub-Saharan Africa, as well as Oman, Pakistan, west coastal India. It grows to a height of 5–12 m, with a trunk up to 30 cm in diameter. Sudan is the source of the world's highest quality gum arabic, known locally as hashab gum in contrast to the related, but inferior, gum arabic from Red acacia or talah gum.
Vachellia nilotica is a tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also a Weed of National Significance and is an invasive species of significant concern in Australia.
The Masoala fork-marked lemur, also known as the eastern fork-marked lemur or Masoala fork-crowned lemur, is a species of lemur found in the coastal forests of northeastern Madagascar. It is a small nocturnal animal with large eyes, greyish fur and a long tail.
Eucalyptus tereticornis is a species of tree native to eastern Australia. E. tereticornis has several common names, including forest red gum, blue gum, flooded gum, grey gum, mountain gum, Queensland blue gum, red gum, bastard box, red ironbark, red irongum and slaty gum.
A teeth cleaning twig or datun is a tool made from a twig from a tree. It can help to prevent tooth decay and gum disease.
Chicle is a natural gum traditionally used in making chewing gum and other products. It is collected from several species of Mesoamerican trees in the genus Manilkara, including M. zapota, M. chicle, M. staminodella, and M. bidentata.
Gum Tree Gully Conservation Park is a protected area in the Australian state of South Australia located in the locality of Hindmarsh Tiers about 55 kilometres (34 mi) south of the state capital of Adelaide and about 6 kilometres (3.7 mi) south-east of Myponga.
