John TI - Phylogenetic relationships and classification in Marantaceae: insights from plastid DNA sequence data JO - Taxon PY - 2006-05-01T00:00:00/// VL - 55 IS - 2 SP - 281 EP - 296 KW - TRNK INTRON KW - TRNL-F INTERGENIC SPACER REGION KW - CLASSIFICATION KW - PHYLOGENY KW - MARANTACEAE KW - MATK N2 - The evolutionary distinctiveness and phylogenetic position of Marantaceae within the Zingiberales is strongly supported, yet relatively little phylogenetic research has been conducted on members of Marantaceae. Phylogenetic analyses of plastid DNA sequence data (matK and 3' intergenic spacer region, and the trnL-F intergenic spacer region) for 80 ingroup taxa representing 27 genera were conducted under parsimony criteria. Results identify five major clades and support significant realignments in tribal and "group" circumscriptions. Four non-monophyletic genera, Calathea, Marantochloa, Phrynium, and Schumannianthus are identified. Although significant work remains to identify relationships of the major lineages within Marantaceae and to redefine several problematic genera, we propose a working classification that better reflects the inferred evolutionary history of the family.
