Myrtaceae occur on all continents except Antarctica. Estimates of numbers of Myrtaceae world-wide suggest between 4600-5800 species. Currently, Myrtaceae is divided into two subfamilies, Myrtoideae and Psiloxyloideae. The former includes fifteen tribes including tribe Myrteae that houses the hyper-diverse genus Eugenia. Phylogenetic analysis shows Eugenia to be monophyletic, comprising eight informal clades. One of these, Eugenia subg. Calycorectes, contains 32 species distributed mainly in the Brazilian Atlantic, as well as Amazon forests. Eugenia subg. Calycorectes is distinguished from other Eugenia by its fused calyx in the bud but this character has been shown to be homoplastic in the family. Outputs from this proposed internship will include 1) a molecular-based phylogeny for which whole genome sequence analysis will be performed at the Royal Botanic Gardens, Kew; this will support a 2) taxonomic monograph and 3) allow testing of historical biogeography hypotheses for Eugenia subg. Calycorectes. Output 1) will allow procurement of morphological synapomorphies based on inflorescence development to be mapped onto the phylogeny, to be generated in the Jodrell Laboratory, Kew. The proposed project will last for 12 months and all steps will be supervised by Dra. Eve J. Lucas who has focused her studies on systematics of Myrtaceae. (AU)
