Canarium Strictum
''Canarium strictum'', known by common names including black dhup, Raal, Raal dhup and black dammar, is a species of tree in the family Burseraceae (the incense tree family). It is known for the medicinal and commercial use of the resin it exudates, called black dammar Dammar, also called dammar gum, or damar gum, is a resin obtained from the tree family Dipterocarpaceae in India and Southeast Asia, principally those of the genera '' Shorea'' or '' Hopea'' (synonym ''Balanocarpus'').

William Roxburgh
William Roxburgh FRSE FRCPE Linnean Society of London, FLS (3/29 June 1751 – 18 February 1815) was a Scottish people, Scottish surgeon and botanist who worked extensively in India, describing species and working on economic botany. He is known as the founding father of Indian botany. He published numerous works on Indian botany, illustrated by careful drawings made by Indian artists and accompanied by taxonomic descriptions of many plant species. Apart from the numerous species that he named, many species were named in his honour by his collaborators. He was the first to document the existence of the Ganges river dolphin. Early life He was born on 3 June 1751 on the Underwood estate near Craigie, South Ayrshire, Craigie in Ayrshire and christened on 29 June 1751 at the nearby church at Symington, South Ayrshire, Symington. His father may have worked in the Underwood estate or he may have been the illegitimate son of a well-connected family. His early education was at Underwood ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Burseraceae
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas. Because of taxonomic revision, as the family size (in terms of genera and species) differs according to the time period of study; so, too, does the family's higher-level relationships, including order. Burseraceae is a genetically-supported monophyletic group since APG III and is frequently cited within the Sapindales. It is recognized as a sister group to the Anacardiaceae. The Burseraceae are characterized by the generally non- allergenic resin they produce in virtually all plant tissue and their dist ...

Dammar Gum
Dammar, also called dammar gum, or damar gum, is a resin obtained from the tree family Dipterocarpaceae in India and Southeast Asia, principally those of the genera ''Shorea'' or ''Hopea'' (synonym ''Balanocarpus''). The resin of some species of ''Canarium'' may also called dammar. Most is produced by tapping trees; however, some is collected in fossilised form on the ground. The gum varies in colour from clear to pale yellow, while the fossilised form is grey-brown. Dammar gum is a triterpenoid resin, containing many triterpenes and their oxidation products. Many of them are low molecular weight compounds (dammarane, dammarenolic acid, oleanane, oleanonic acid, etc.), which easily oxidizes and photoxidizes. Types * ''Damar mata kucing'' ('cat's eye damar') is a crystalline resin, usually in the form of round balls. ''Shorea javanica'' is an important source in Indonesia. * ''Damar batu'' ('stone damar') is stone or pebble-shaped, opaque dammar collected from the ground. * ...
