Subsequent cooling and drying of the global climate caused two lineages of the Protieae to move south, one towards the Old World tropics and another towards South America.
We recognize the support of U. Annual Review of Ecology and Systematics Retrieved 13 March Similar results from other studies   find that Beiselia mexicanaa native of Mexico, is basal to the remaining Burseraceae. Burseraceae Kunth  Genera See text The Burseraceae are a moderate-sized family of genera and about species of flowering famikia. Characterization of the balm of an Egyptian mummy from the Seventh Century B. In tribe Bursereae, Bursera moves toward absorbing Commiphoraas recent phylogenetic analyses are revealing new patterns within traditional lineages, with Bursera subgenus Elaphrium Jacq.
Still, there is strong cause for hope. The liquid sap hardens and is gathered, sold as is or further processed and mixed with spices, seeds, and roots to make various forms of incense. Some discrepancy exists in the literature about the size of the Burseraceae.
The following discusses the current status of research on the family on several scales as it becomes one of the better studied families in Amazonia. Just as the family size in terms of genera and species differs according to the time period of the study, so, too, does its placement in the higher ranks.
A Broader View of Amazonian Burseraceae Our rapidly improving understanding of Burseraceae systematics and biogeography, combined with the family’s diversity, ecological importance, and habitat specialization in the Amazon region, make it an excellent group for studying the Amazon flora.
Silvics of North America. Despite the large cluster of Protium species towards the top of Figure 2 that are unassigned to sections, it includes some well-supported groups that are united by morphological characters and thus could become new named sections in the future. A well-studied group of plants can serve as a model for many different avenues of biological investigation, if the group’s state of the art includes three main components: In their ecological importance, the Burseraceae are on a par with all of the great families of trees in Amazonia and the Guianas, but the manner in which this importance is achieved differs from one region to another.
Biochemical Systematics and Ecology, These advances will further increase the value of well-studied plant groups as models for research on floristics, conservation, and speciation. Phylogeny of Acridocarpus-Brachylophon Malpighiaceae: The Burseraceae comprise an excellent model for studying Amazonia because of its high diversity, ecological importance, diversity of habitats occupied, and habitat specificity.
Burseraceae – Wikipedia
From Wikipedia, the free encyclopedia. Burseracexe the removal of Trattinnickia Willd. Another traditional character set that inexplicably has been neglected to date in the family is leaf let anatomy, and we have begun to build a more extensive collection of liquid-preserved leaf material; one curious aspect of Burseraceae leaflet morphology is the pulvinulus, and lab studies are needed to determine its anatomical structure and whether these are “present” anatomically even when they are not visible in taxa normally characterized by them.
Meanwhile, there is still a severe shortage of professional and productive in the sense of publications botanists based in Amazonia; there are still campuses of federal universities that do not have a single Ph.
Access to biodiversity for researchers has improved, and there are some embryonic efforts at international cooperation in frontier regions of Amazonia; this includes Colombia, where very recently botanical exploration has become markedly safer and more feasible.
Commonly known bursegaceae tabonuco or gommier, also candlewoodDacryodes excelsa is a large, dominant tree found in Puerto Rico and other parts of the Caribbean. Though this is a small subset of the large number of potentially important species, these four members exemplify the wide use and importance of the Burseraceae. The Sapindales are contained within the malvids of the rosid clade within the eudicotyledons.
Generic limits and many relationships within Protieae historically have proven difficult to resolve based on morphology alone e. On 28 plots of 0. The families and genera of vascular plants. Molecular-based Phylogeny and Taxonomic Questions in Protieae Generic limits and many relationships within Protieae historically familis proven difficult to resolve based on morphology alone e.
The clear sap oozes from the tree and hardens to a white, famllia waxy resin that can be used to make candles bursersceae incense.
Drukkerij Koch en Knuttel, Gouda. The Burseraceae are distributed throughout the world and primarily in the burseracear, especially MalaysiaAfrica, and Central and South America.

Phylogenetic relationships in Burseraceae based on plastid rps 16 intron sequences. The next divergence was in the Early Eocene when the Burserinae i. World pollen and spore flora Introduction Why a Global Approach? Finally, the namesakes of the family Boswellia carterii frankincense and Commiphora abyssinica myrrh are important economically and medicinally in several parts of the world.
Molecular phylogenetic analysis of Commiphora Burseraceae yields insight on the evolution and historical biogeography of an “impossible” genus. Barriers to Progress The obstacles to progress in the study of the Burseraceae are those faced by all Amazonian botanists, but this does not make them any less damaging nor bring them closer to resolution.
More specifically, the earliest diverging genus was Beiselia of the Bursereae subtribe Boswelliinae in either North America, Mexico, or the Caribbean in the Paleocene. The leaves are generally alternate, spiral, and odd-pinnately compound with opposite, frequently long-petiolulate, entire to serrate, pinnately veined leaflets whose symmetry is distinctive in some genera. Like all members, the tree releases sap from the bark when wounded. The mechanism of seed dispersal via animal link vectors endozoochoric dispersal may explain how most Burseraceae were able to expand their range so efficiently across the globe.
The latter four genera occur on at least two continents, and four genera in the family butseraceae have more than species: Molecular Phylogenetics and Evolution Botanical exploration and the number of botanical collections generated are both drastically down from the levels of activity ten years ago, and some high-profile but ill-conceived bueseraceae in Amazonia have proven to be expensive, ineffective in their geographic coverage, and wasteful in that they are producing large numbers of mostly useless sterile collections.
For example, most bursdraceae not all of the clade that includes Protium altsonii Sandwith, P. It is important to be very cautious when making sweeping interpretations of biogeographic history when one does not have a comprehensive sample of all of the taxa including extinct species. In Burseraa broad sampling was important to determine the relationships of the Antillean species with their relatives in mainland Central and South America.
Although the resolution of certain clades is still vague, it was possible to determine that the islands were colonized from Central America by two distinct lineages, and that most species are restricted endemics that radiated during the Middle Miocene to Pliocene De-Nova et al.
