Commiphora is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America. [2] [3] [1] The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.
The common name myrrh refers to several species of the genus, from which aromatic resins are derived for various fragrance and medicinal uses by humans.
A previously unknown species belonging to this genus has been grown from a single ancient seed and tentatively identified as the biblical plant mentioned in the Bible as the source of a medicinal extract called tsori. [4]
Leaves in Commiphora are pinnately compound (or very rarely unifoliolate). Many species are armed with spines. Bark is often exfoliating, peeling in thin sheets to reveal colorful, sometimes photosynthetic, bark below. Stems are frequently succulent, especially in species native to drier environments. Flowers are typically dioecious (subdioecious) and fruits are drupes, usually with a 2-locular ovary (one is abortive). [5] In response to wounding, the stems of many species will exude aromatic resins.
Commiphora can serve as a model genus for understanding plant evolution in the drier regions of the Old World tropics, particularly in eastern continental Africa and Madagascar, where diversity in the genus is concentrated. The closely related sister genus to Commiphora, Bursera , has been used as a model genus to study patterns of evolution in the New World seasonally dry tropical forests. [6]
Products from many species of Commiphora have been used for various purposes, sometimes as timber, building material, and natural fencing, but more often valued for the aromatic resins produced by several members of the genus. "Myrrh", the common name for these dried resins, is fragrant and has been used both as fragrance and for medicinal purposes (e.g., Balsam of Mecca, C. gileadensis). [7] Use of myrrh resin is frequent and pronounced throughout historical texts of cultural significance, including the Bible.
An ancient seed recovered from an archaeological site in the Judean Desert has been confirmed to be a member of Commiphora. [8] The 1,000-year-old seed has produced a tree growing at Louis Borick Natural Medicine Research Center. [9]
Studies using DNA sequence data have confirmed the monophyly of Commiphora; [3] [10] however, this data suggests that previous classification of the genus into sections does not reflect monophyletic interspecific relationships.

Canarium is a genus of about 120 species of tropical and subtropical trees, in the family Burseraceae. They grow naturally across tropical Africa, south and southeast Asia, Indochina, Malesia, Australia and western Pacific Islands; including from southern Nigeria east to Madagascar, Mauritius, Sri Lanka and India; from Burma, Malaysia and Thailand through the Malay Peninsula and Vietnam to south China, Taiwan and the Philippines; through Borneo, Indonesia, Timor and New Guinea, through to the Solomon Islands, Vanuatu, New Caledonia, Fiji, Samoa, Tonga and Palau.
Ochna is a genus comprising 79 species of evergreen trees, shrubs and shrublets belonging to the flowering plant family Ochnaceae. These species are native to tropical woodlands of Africa, Madagascar, the Mascarenes and Asia. Species of this genus are usually called ochnas, bird's-eye bushes or Mickey-mouse plants, a name derived from the shape of the drupelet fruit. The name of this genus comes from the Greek word ὄχνη (ókhnē), used by Theocritus and meaning "wild pear", as the leaves are similar in appearance. Some species, including Ochna integerrima and O. serrulata, are cultivated as decorative plants.
Boswellia is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana. Boswellia species are moderate-sized flowering plants, including both trees and shrubs.
Sesamum is a genus of about 20 species in the flowering plant family Pedaliaceae. The plants are annual or perennial herbs with edible seeds. The best-known member of the genus is sesame, Sesamum indicum, the source of sesame seeds. The species are primarily African, with some species occurring in India, Sri Lanka, and China. The origin of S. indicum is uncertain, as it is widely cultivated and naturalized in tropical regions. The genus is closely related to the strictly African genus Ceratotheca and is itself probably African in origin.
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.
Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.
Cleome is a genus of flowering plants in the family Cleomaceae, commonly known as spider flowers, spider plants, spider weeds, or bee plants. Previously, it had been placed in the family Capparaceae, until DNA studies found the Cleomaceae genera to be more closely related to the Brassicaceae than the Capparaceae. Cleome and clammyweed can sometimes be confused.
Tephrosia is a genus of flowering plants in the family Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions.
Blepharis is a genus of plant in family Acanthaceae. It contains around 128 species found in seasonally dry to arid habitats from Africa through Arabia to Southeast Asia. In section Acanthodium, there are 13–15 species that use the C4 carbon fixation pathway. Phylogenetic analysis suggests that this pathway evolved up to three times independently in the genus over the last five million years.
Gnidia is a genus of flowering plants in the family Thymelaeaceae. It is distributed in tropical and southern Africa and Madagascar; more than half of all the species are endemic to South Africa. Gnidia was named for Knidos, an Ancient Greek city located in modern-day Turkey.
Zygophyllum is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (zygon), meaning "double", and φυλλον (phyllon), meaning "leaf". It refers to the leaves, each of which have two leaflets.
Opopanax is the commercial name of bisabol or bissabol, the fragrant oleo-gum-resin of Commiphora guidottii. It has been a major export article from Somalia since ancient times, and is called hebbakhade, habaghadi or habak hadi in Somali. It is an important ingredient in perfumery and therefore known as scented myrrh, sweet myrrh, perfumed myrrh or perfumed bdellium.
Tetraena is a genus of flowering plants in the family Zygophyllaceae.
Basananthe is a genus of flowering plants belonging to the family Passifloraceae.
Commiphora guidottii, commonly known as scented myrrh or bisabol, is a tree or shrub species that is native to Somalia and Ethiopia. Essential oil from its oleo-gum-resin has been researched for its use in topical treatment of wounds.
