A Synopsis Of Melanthiaceae (Liliales) With Focus On Character Evolution In Tribe Melanthieae, Wendy B. Zomlefer, Walter S. Judd, W. Mark Whitten, Norris H. Williams
Aliso: A Journal of Systematic and Floristic Botany
Melanthiaceae s.l. comprises five tribes: Chionographideae, Heloniadeae, Melanthieae, Parideae, and Xerophylleae—each defined by distinctive autapomorphies. The most morphologically diverse tribe Melanthieae, now with seven genera, had not been subject to rigorous phylogenetic character study prior to the current series of investigations that also include an overview of the family. Data from our publications and studies underway are here assessed and integrated, providing a useful overview of Melanthiaceae, and especially of Melanthieae. The results of parsimony analyses of ITS (nuclear ribosomal) and trnL-F (plastid) DNA sequence data correlate with potentially synapomorphic phenotypic characters for genera of Melanthieae, including habit form, …
Patterns In Evolution In Characters That Define Iris Subgenera And Sections, Carol A. Wilson
Patterns In Evolution In Characters That Define Iris Subgenera And Sections, Carol A. Wilson
Aliso: A Journal of Systematic and Floristic Botany
Subgeneric groups have been circumscribed in Iris based on a small number of morphological characters. Recent DNA sequence data has indicated that several of the subgenera, sections, and series that have previously been delineated are paraphyletic or polyphyletic. The evolution of characters that have traditionally been used to distinguish sub generic and sectional groups within Iris was investigated by mapping these characters on a phylogenetic tree based on matK sequence data. Results indicate that rhizomes are pleisomorphic for the genus and that three bulb types have arisen independently. My analysis shows that sepal beards, sepal crests, and seed arils …
Phlogeny And Biogeography Of The Prayer Plant Family, Linda M. Prince, W. John Kress
Phlogeny And Biogeography Of The Prayer Plant Family, Linda M. Prince, W. John Kress
Aliso: A Journal of Systematic and Floristic Botany
Marantaceae are the second largest family in the order Zingiberales, with approximately 31 genera and 535 species. Earlier studies based on morphological and molecular characters could not confidently determine the relationships among major lineages of the family, nor could they identify the basal branch of the family tree. Phylogenetic analyses of DNA sequence data from all three genomic compartments (chloroplast: matK, ndhF, rbcL, rps16 intron, and trnL-trnF intergenic spacer; mitochondrion: cox1; nucleus: ITS region and the 5'-end of 26S) for a restricted set of taxa were conducted under parsimony criteria to define …
