Unraveling the evolutionary radiation of the families of the Zingiberales using morphological and molecular evidence.
Evidence from branch lengths in the parsimony analyses and from the fossil record suggests that the Zingiberales originated in the Early Cretaceous and underwent a rapid radiation in the mid-Cretaceous, by which time most extant family lineages had diverged. Expand

Increased character sampling seems to be more important than increased taxon sampling; a comparison of the full and reduced datasets suggests little difference in core topology but considerably more nodal support with the increased character sample sizes, indicating a general trend toward a stable estimate of phylogenetic relationships for the Palmae.

Phylogenetic Relationships of Monocots Based on the Highly Informative Plastid Gene ndhF
The resulting tree is highly resolved and places commelinids sister to Asparagales, with both sister to Liliales-Pandanales in the strict consensus; Pandanales are sister to Dioscoreale in the bootstrap majority-rule tree, just above Petrosaviales. Expand

Biogeographic interpretation suggests a Gondwanan origin for the Arecoid Line with several lineages found on more than one fragment of the former supercontinent and primary diversification in these groups possibly due to continental breakup vicariance. Expand
Thorn-like prickles and heterophylly in Cyanea: adaptations to extinct avian browsers on Hawaii?
It is proposed that thorn-like structures in Cyanea (Campanulaceae) on Hawaii arose as mechanical and visual defenses against herbivory by flightless geese and goose-like ducks that were extirpated by Polynesians within the last 1600 years. Expand
Phylogenetic relationships and biogeography of Fuchsia (Onagraceae) based on noncoding nuclear and chloroplast DNA data.
Parsimony and maximum likelihood analyses with nuclear ITS and chloroplast trnL-F and rpl16 sequence data for 37 taxa representing all sections of Fuchsia and four outgroup taxa support previous sectional delimitations, except for F. verrucosa, which is described here as a new section VerrucosA.

Paraphyly in Tribe Onagreae: Insights into Phylogenetic Relationships of Onagraceae Based on Nuclear and Chloroplast Sequence Data
Abstract Onagraceae are a family of 17 genera in seven tribes, with the majority of species in tribes Onagreae and Epilobieae. Despite the species-richness of these two tribes, to date noExpand
