Baobab (Not Boabab) Species General Background Germinating
Baobab (not Boabab) Species Baobab is the common name of a genus (Adansonia) with eightspecies of trees, 6 species in Madagascar; 1 in Africa and 1 in Australia. Adansonia gregorii (A.gibbosa) or Australian Baobab (northwest Australia) Adansonia madaf Zascariensis or Madagascar Baobab (Madagascar) Adansonia perrieri or Perrier's Baobab (North Madagascar) Adansonia rubrostipa or Fony Baobab (Madagascar) Adansonia suarezensis or Suarez Baobab Diego Suarez,(Madagascar) Adansonia za or Za Baobab (Madagascar) The name Adansonia honours Michel Adanson, the French naturalist and explorer who described A. digitata. General Background One of the earliest written references to the Baobab tree was made by the Arabic traveller, Al-Bakari in 1068. In 1592, the Venetian herbalist and physician, Prospero Alpino, reported a fruit in the markets of Cairo as "BU HUBAB". It is believed that the name is derived from the Arabic word Bu Hibab which means fruit with many seeds. Common names include bottle tree and monkey bread tree. Baobab - derived from African fokelore "upside-down-tree". The story is after the creation each of the animals were given a tree to plant and the stupid hyena planted the baobab upside-down. The baobab is the national tree of Madagascar. Height is 5-25m tall and trunk diameter of up to 7m. The Baobab can store up to 120 000 lt of water inside the swollen trunk to endure harsh drought conditions. All occur in seasonal arid areas and are deciduous, losing leaves during dry season. It is believed that the elephant must digest the seed before it will germinate as the heat and stomach acids help to soften the shell. -

Large‐Scale Genomic Sequence Data Resolve the Deepest Divergences in the Legume Phylogeny and Support a Near‐Simultaneous Evolutionary Origin of All Six Subfamilies
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Large‐scale genomic sequence data resolve the deepest divergences in the legume phylogeny and support a near‐simultaneous evolutionary origin of all six subfamilies Koenen, Erik J M ; Ojeda, Dario I ; Steeves, Royce ; Migliore, Jérémy ; Bakker, Freek T ; Wieringa, Jan J ; Kidner, Catherine ; Hardy, Olivier J ; Pennington, R Toby ; Bruneau, Anne ; Hughes, Colin E Abstract: Phylogenomics is increasingly used to infer deep‐branching relationships while revealing the complexity of evolutionary processes such as incomplete lineage sorting, hybridization/introgression and polyploidization. We investigate the deep‐branching relationships among subfamilies of the Leguminosae (or Fabaceae), the third largest angiosperm family. Despite their ecological and economic importance, a robust phylogenetic framework for legumes based on genome‐scale sequence data is lacking. We generated alignments of 72 chloroplast genes and 7621 homologous nuclear‐encoded proteins, for 157 and 76 taxa, respectively. We analysed these with maximum likelihood, Bayesian inference, and a multispecies coa- lescent summary method, and evaluated support for alternative topologies across gene trees. We resolve the deepest divergences in the legume phylogeny despite lack of phylogenetic signal across all chloroplast genes and the majority of nuclear genes. Strongly supported conflict in the remainder of nuclear genes is suggestive of incomplete lineage sorting. All six subfamilies originated nearly simultaneously, suggesting that the prevailing view of some subfamilies as ‘basal’ or ‘early‐diverging’ with respect to others should be abandoned, which has important implications for understanding the evolution of legume diversity and traits. -

While a number of tree species had been brought under CITES regulation over the previous decades1, COP-17 saw a marked expansion of CITES timber species listings. The Parties at COP-17 listed the entire Dalbergia genus (some 250 species, including many of the most prized rosewoods), Pterocarpus erinaceous (kosso, a highly-exploited rosewood species from West Africa) and three Guibourtia species (bubinga, another African rosewood) to CITES Appendix II.2 The new listings entered into force on January 2, 2017. -

Evolutionary Consequences of Dioecy in Angiosperms: the Effects of Breeding System on Speciation and Extinction Rates
EVOLUTIONARY CONSEQUENCES OF DIOECY IN ANGIOSPERMS: THE EFFECTS OF BREEDING SYSTEM ON SPECIATION AND EXTINCTION RATES by JANA C.

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems.
