FAMILIA BURSERACEAE PDF

Many of the new taxa worldwide are not yet represented by material adequate for publishing them. For example, Protium fragrans from Cuba falls neatly within a well-supported Icicopsis clade, as originally proposed by Swart burseracsae, similarly, the Guianas endemic P. There is surprising evidence for B. 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. Icicopsisan object of current revision, is both variable and repetitive vegetatively while the fruits rarely help; it is possible that hair types and surface features like lenticels will yield useful keys. Preliminary study of the anti-inflammatory activity of hexane extract and fractions from Bursera simaruba Linneo Sarg.

Taxonomy of Vascular Plants. Birseraceae into the historical construction of species-rich Mesoamerican seasonally dry tropical forests: Acta Botanica Mexicana ProtiumCommiphoraBurseraand Canarium Daly et al. Finally, the namesakes of the family Boswellia carterii frankincense and Commiphora abyssinica myrrh are important economically and medicinally in several parts of the world. 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 famolia, the Mexican endemic Beiselia is indicated as a monotypic tribe basal to the rest of the family Fig.

In the Biological Dynamics of Forest Fragments project in Central Amazonia, the family was 2nd in relative diversity, with 49 species, and Protium was burseraxeae most speciose genus 35 spp. Burseraceae It is important to be very cautious when making fa,ilia interpretations of biogeographic history when one does not have a comprehensive sample of all of the taxa including extinct species. For example, in the early 19th century, the family seems to have been placed in the Burseraleswith the Anacardiaceae and Podoaceae.

In modern times resins from these trees are used in Chinese herbal medicine and Indian Ayurvedic medicine to treat several ailments. Perspectives in biology and medicine 48 2. The Burseraceae are a moderate-sized family of genera and about species of flowering plants. The Protieae are examined in more detail below. The molecular systematics and biogeography of the Burseraceae. Second, Bursera simaruba of the Burserinae is a fast-growing ornamental that is one of a few representatives of the primarily tropical family in the United States.

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. Burseraceae: a model for studying the Amazon flora Retrieved 13 March It is impossible to decipher an Amazonian group without a global grasp of the group, particularly in adjacent floras. Three additional groups of species merit similar investigations. Nevertheless, the family is a genetically supported monophyletic group fmilia and frequently cited within the Sapindales and is recognized as a sister group to the Anacardiaceae.

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. Thorough sampling is absolutely essential, as bursreaceae a rigorous taxonomic foundation, and taxonomic revisions should be complemented by ecological and physiological studies.

This sets the stage for the revealing analyses that can be conducted using molecular phylogenies. Burseraceae by Thais Nogueira on Prezi Molecular Phylogenetics and Evolution, This is a list of the 19 genera of the Burseraceae with placement in tribe and subtribe where applicable: As an example, in a lowland forest in Sarawak, the Burseraceae comprised the third most important tree family in relative density, second in basal area, and ninth in relative diversity, and it accounted for five of top 20 species in bursdraceae frequency Lee et al.

As for key taxa, during the same period we were finally able to collect and sample several key taxa for the first time: One issue that will be helped by molecular studies at infra- specific rank is the question of whether one or famiilia clusters of names that have been synonymized are in fact complexes of closely related species; these include Protium decandrum Aubl.

As for the Protieae, our phylogeny in Figure 2 reveals a similar story.

Gataur More specifically, the earliest diverging genus was Beiselia of the Bursereae subtribe Boswelliinae in either North America, Mexico, or the Caribbean in the Paleocene. In Burseraa broad sampling was important to determine the relationships of the Antillean species with their relatives in mainland Central and South America. For example, most if not all of the clade that includes Protium altsonii Sandwith, P. Biodiversity Heritage Library Perspectives in biology and medicine 48 2. 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. The resin of the Burseraceae is nonallergenic and two ovules per carpel occur, whereas the resin of the Burserceae can be allergenic or poisonous and one ovule per carpel is found.

Burseraceae

Order[ edit ] According to the literature, the Burseraceae have not been lumped with other families nor split up into several others. However, they have jumped orders several times. For example, in the early 19th century, the family seems to have been placed in the Burserales , with the Anacardiaceae and Podoaceae. 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. One such cladogram indicated that the Sapindales are robust and that the Burseraceae and Anacardiaceae are within a single clade. 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. For example, members of the tribe Protieae are generally found in South America, those of the Bursereae are found in Africa and Mesoamerica , while members of the Canarieae are found in Malaysia.
