  title={Phylogenetic Relationships and Evolution in the Strelitziaceae (Zingiberales)},
  author={Glynis V Cron and Cary Pirone and Madelaine E Bartlett and W. John Kress and Chelsea D. Specht},
Abstract Evolutionary trends and phylogenetic relationships in the Strelitziaceae (Zingiberales) were investigated using sequence data from ten plastid and two nuclear regions and a morphological dataset. [...] Key Result Relationships among the genera remain equivocal with two hypotheses emerging: (i) Strelitzia sister to a clade comprising Ravenala and Phenakospermum when indels are included, or (ii) Ravenala sister to the remainder of the Strelitziaceae when indels are excluded in/from the combined…Expand
Revisiting the Zingiberales: using multiplexed exon capture to resolve ancient and recent phylogenetic splits in a charismatic plant lineage
The concatenated plastid and nuclear dataset supports the position of Musaceae as sister to the remaining seven families and recovers known intra- and inter-family phylogenetic relationships with generally high bootstrap support. Expand
Inflorescence and Flower Development in Orchidantha chinensis T. L. Wu (Lowiaceae; Zingiberales): Similarities to Inflorescence Structure in the Strelitziaceae
Inflorescence and flower structure is now well established in this small but important family of plants, and similarities between the Lowiaceae and Strelitziaceae include inflorescence structure; the presence of a long prolongation of the ovary; and a delay in the formation of the third sepal during flower development.

Spatio‐temporal history of the endemic genera of Madagascar
An Eocene/Oligocene onset for the origin of the Madagascan generic endemic flora, with the majority arising in the Miocene or more recently is supported, de-emphasize the importance of the Gondwanan break-up on the evolution of the flora. Expand
Species diversity driven by morphological and ecological disparity: a case study of comparative seed morphology and anatomy across a large monocot order
Multiple radiations into temperate habitats were found to not be driven by morphological change, but instead may point to a genetic plasticity in the family that provided opportunities for speciation events not found anywhere else in the order. Expand
Strelitzia nicolaii Regel & Körn. (Strelitziaceae), a casual alien plant new to Northern Hemisphere
The ongoing naturalization of the blue giant paradise bird tree, Strelitzia nicolaii, is here reported for the first time for NW Sicily (Italy). Native to SE Africa, this ornamental plant was locallyExpand
On the real identity of the Strelitzia cultivated in Sicily’s historic gardens
The authors, on the basis of field observations and literature search, conclude that all tree-like plants of Strelitzia grown in Sicily belong to Strelitzia nicolaii. Therefore Strelitzia alba (=Expand

Phylogeny of Orchidantha (Lowiaceae) and the Zingiberales Based on Six DNA Regions
A phylogenetic analysis of Zingiberales based on 613 parsimony informative characters of the plastid matK gene, the trnL-trnF region, the rps16 intron, and a conservative part of the nuclear ribosomal ITS region indicates that Lowiaceae is sister to all the remaining families of Zediberales. Expand
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
Phylogenetic estimation of the core Bromelioids with an emphasis on the genus Aechmea (Bromeliaceae).
Several genera and subgenera of Aechmea with species in disjunct geographic locations are found to be polyphyletic, divided into separate clades that reflect geographic distribution rather than morphological similarity, suggesting that certain morphological characteristics thought to be indicative of common ancestry have instead evolved multiple times in parallel.

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
Phylogenetic analysis of the Zingiberales based on rbcL sequences.
A parsimony analysis of DNA sequences from the chloroplast-encoded gene, rbcL, for 2 1 species of Zingiberales and proposed relatives results in the same most parsimonious tree for taxa within the Zingibales and the immediate outgroup. Expand
Large indels obscure phylogeny in analysis of chloroplast DNA (trnL-F) sequence data: Pomaderreae (Rhamnaceae) revisited
Phylogenetic analysis of 69 ingroup-taxa of Pomaderreae using trnL-F sequences confirm the monophyly of the tribe and two new genera containing atypical species of Stenanthemum are suggested. Expand
The evolutionary and biogeographic origin and diversification of the tropical monocot order zingiberales
Ancestral Gondwanan vicariance combined with a potential Laurasian distribution and multiple secondary dispersal events within families during the Tertiary can explain the main biogeographic events leading to the current pantropical distribution of this tropical order. Expand
Phylogeny of Castanea (Fagaceae) based on chloroplast trnT-L-F sequence data
The trnT-L region was found to be the most variable and informative region and may explain the high proportion of transversions found in this region where as comparatively lower A+T values were found in the trnL intron and spacer regions with relatively balanced numbers of transitions and transversions.

Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms. Expand
