ProtiumCommiphoraBurseraand Canarium Daly et al. Towards a New Subfamilial Classification Until recently, the subfamilial classification of the Burseraceae was in a fascinating state of flux, but as molecular systematic investigations progress and the results are reconciled with morphology, the Mexican endemic Beiselia is indicated as a monotypic tribe basal to the rest of the family Fig.
These issues extending beyond the limits of Amazonia also go well beyond nomenclature, because they affect conclusions about diversity, endemism, biogeography, and conservation. 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.
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. Clarified higher-level phylogenetic relationships open the door to more refined systematics of clades without having to worry if they are para- or polyphyletic.
In modern times resins from these trees are used in Chinese herbal medicine and Indian Ayurvedic medicine to treat several ailments. Manual of leaf architecture. The Burseraceae are characterized by the nonallergenic resin they produce in virtually all plant tissue and the distinctive smooth, yet flaking, aromatic bark.
A well-studied group can also be an excellent testing ground for new or under-utilized tools and independent data sets. Molecular approaches are already making inroads into some of the most stubborn problems in higher-level Burseraceae classification, and examples have been cited of issues where this will prove to be the case at lower ranks as well, but additional tools hold great promise.
Articles with ‘species’ microformats Commons category link is on Wikidata. In eastern Amazonia and the Burseraceea, the importance of the Burseraceae is due primarily to their great numbers.
For example, Beiselia mexicana Forman was recently proposed to constitute a distinct tribe basal to the rest of the Burseraceae Thulin et al.
Overall, the Burseraceae score somewhat higher in relative density than in relative diversity number of species and far higher in relative density than in relative “dominance” basal areaas they tend to be small to medium-sized trees. Preliminary study of the anti-inflammatory activity of hexane extract and fractions from Bursera simaruba Linneo Sarg.

According to the literature, the Burseraceae have not been lumped with other families nor split up into several others. In Burseraa broad sampling was important to determine the relationships of the Antillean species with their relatives in mainland Central and South America.
As for key taxa, during the same period we were finally able to collect and sample several key taxa for the first time: For example, members of the tribe Protieae are generally found in South America, those of the Bursereae are found in Africa and Mesoamericawhile members of the Canarieae are found in Malaysia.
These advances will further increase the value of well-studied plant groups as models for research on floristics, conservation, and speciation. The molecular-based phylogeny has also contributed to the circumscription of these sections, including unusual taxa that were misplaced on first examination.
The phylogenetic history and biogeography of the frankincense and myrrh family Burseraceae based on nuclear and chloroplast sequence data.
Acta Botanica Mexicana Our results to date are compatible with the scenario of the Amazon flora as relatively young, with groups like the Burseraceae undergoing relatively recent and rapid speciation.
The synapomorphies of the Sapindales include pinnately compound, alternate and spiral leaves that may be palmately compound, trifoliate, or unifoliate, and small four- or five-merous flowers having a characteristic nectar disk and imbricate petals and sepals. The actual numbers differ according to the time period in which a given source is written describing this family. Acknowledgements We recognize the support of U. The gumbo limbo grows quickly and can be used to make a living fence especially out of cut familoa that are placed straight into the ground or for restoration projects as a pioneer species.
Finally, the surprising number of Andean Protium species, most of them recently discovered and still undescribed, invite investigation as to whether colonization of montane habitats has occurred multiple times and relatively recently.
Fossils of the Protieae, Canariae and Bursereae have been found in London and Florissant, Colorado, even though those lineages no longer occur in the Northern Hemisphere outside of the tropics. The white-sand specialists Protiumreticulatum Engl. Burseraceae in Eastern Amazonia and the Guianas. The family is remarkable for having a high number of congeners in limited areas. Diversification in the family occurs via multiple mechanisms, even within some clades, but in Amazonia, in the absence of obvious barriers to genetic exchange, divergence via habitat shifts is likely to be more prevalent than in other regions.
One issue that will be helped by molecular studies at infra- specific rank is the question of whether one or more clusters of names that have been synonymized are in fact complexes of closely related species; these include Protium decandrum Aubl. Very few Neotropical Burseraceae are mostly or exclusively floodplain species e. The resin of the Burseraceae is nonallergenic and two ovules per carpel occur, whereas the resin of the Anacardiaceae can be allergenic or poisonous and one ovule per carpel is found.
It is impossible to decipher an Amazonian group without a global grasp of the group, particularly in adjacent floras. A taxonomic revision of Protium Burm. Many of the new taxa worldwide are not yet represented by material adequate for publishing them.

Characterization of the balm of an Egyptian mummy from the Seventh Century B. Journal of Tropical Forest Science In the Biological Dynamics of Forest Fragments project in Central Amazonia, the family was 2nd in relative diversity, with 49 species, and Protium was the most speciose genus 35 spp.
