Rapateaceae (16 genera, ˜100 species) is largely restricted to the tepuis and sandplains of the Guayana Shield in northern South America, with Maschalocephalus endemic to West Africa. The family has undergone extensive radiation in flower form, leaf shape, habit, and habitat. To analyze the evolution of these distributions and traits, we derived a molecular phylogeny for representatives of 14 genera, based on sequence variation in the chloroplast‐encoded ndhF gene. The lowland subfamily… 
Phylogeny, adaptive radiation, and historical biogeography in Bromeliaceae: insights from an eight-locus plastid phylogeny.
TLDR
A bromeliad phylogeny based on eight plastid regions is used to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of b romeliad evolution and invasion of different regions, and provide the basis for future analyses of trait evolution and rates of diversification.
PHYLOGENY, CONCERTED CONVERGENCE, AND PHYLOGENETIC NICHE CONSERVATISM IN THE CORE LILIALES: INSIGHTS FROM rbcL AND ndhF SEQUENCE DATA
TLDR
The core Liliales provide compelling examples of both concerted convergence and phy‐logenetic niche conservatism in the context‐specific adaptive value of each of these traits, as well as evidence of parallel trends in other groups.
Molecular Phylogenetics and Patterns of Floral Evolution in the Ericales
TLDR
It is demonstrated that sympetaly is a homoplasious character in the order, that a diplostemonous floral ground plan likely arose from haplostemonic flowers in Ericales, and that the combination of ovules with a single integument and cellular endosperm formation is characteristic for two of the major clades in theOrder.
Phylogenetic Relationships and Character Evolution of Rhodiola (Crassulaceae) based on Nuclear Ribosomal ITS and Plastid trnL-F and psbA-trnH Sequences
TLDR
The phylogenetic relationships within Rhodiola remain poorly understood largely because of difficulties in collecting samples and specimens, but it is suggested that Rhodiola and Pseudosedum form a well-supported clade.
Phylogenetic relationships in subfamily Tillandsioideae (Bromeliaceae) based on DNA sequence data from seven plastid regions.
TLDR
Results of the combined data set clearly show that subfamily Tillandsioideae is monophyletic, and the earliest divergence separates a lineage comprised of Glomeropitcairnia and Catopsis from the "core" tillandsioids.
THE GEOGRAPHICAL PATTERN OF SPECIATION AND FLORAL DIVERSIFICATION IN THE NEOTROPICS: THE TRIBE SINNINGIEAE (GESNERIACEAE) AS A CASE STUDY
TLDR
The results failed to indicate a tendency for sympatric taxa to minimize morphological and phenological overlap (geographic exclusion and/or character displacement hypotheses), and point toward adaptation in phenology to local conditions and buildup of sympatries at random with respect to flower morphology.
Geographic patterns of genetic and morphological variation of the Sicilian wall lizard Podarcis wagleriana
TLDR
The authors' results indicated that in most cases the variation was spatially structured and could be explained as the result of phenotypic plasticity or adaptations to local environmental and ecological conditions, however, some characters showed also concordance with genetic patterns, indicating that the long persistence in Pleistocene refugia could have also triggered natural selection on certain characters.

Chloroplast DNA evidence of colonization, adaptive radiation, and hybridization in the evolution of the Macaronesian flora.
TLDR
The patterns of phylogenetic relationships in Argyranthemum indicate that interisland colonization between similar ecological zones is the main mechanism for establishing founder populations, combined with rapid radiation into distinct ecological zones and interspecific hybridization is the primary explanation for species diversification.
A common origin for woody Sonchus and five related genera in the Macaronesian islands: molecular evidence for extensive radiation.
TLDR
Increase of woodiness is concordant with other insular endemics and refutes the relictural nature of woody Sonchus in the Macaronesian islands and indicates that the alliance probably occurred in the Canary Islands during the late Miocene or early Pliocene.
A Phylogenetic Analysis of Epilobium (Onagraceae) Based on Nuclear Ribosomal DNA Sequences
TLDR
The molecular phylogeny is compatible with some important independent characters and is useful for interpreting morphological and cytological evolution in Epilobium.
Polyphyly and convergent morphological evolution in Commelinales and Commelinidae: evidence from rbcL sequence data.
TLDR
The numbers of species in families of the revised Commelinidae are related partly to the extent of adaptive radiation in those families, but seem more strongly related to nonadaptive features promoting speciation, such as restricted seed dispersal, polyploidy, aneuploidsy, and apomixis.
Radiation of the endemic genus Dendroseris (Asteraceae) on the Juan Fernandez Islands: evidence from sequences of the its regions of nuclear ribosomal DNA
TLDR
Phylogenetic relationships among nine of the 11 species of the endemic genus Dendroseris on the Juan Fernandez Islands were inferred from nucleotide sequences of the internal transcribed spacer regions (ITS) of the 1 8-26S nuclear ribosomal DNA, supporting the hypothesis of rapid adaptive radiation of DENDroser is on the islands.
Origin of the Woody Macaronesian Sempervivoideae and the Phylogenetic Position of the East African Species of Aeonium
TLDR
The extremely close genetic ties among the woody and branched (sub)shrubs indicate that, when compared to the other species of the genus, the wooded, African Aeonium species are not the sister group of the Macaronesian Sempervivoideae and substantiate the view that an ancestor of A. leucoblepharum recently migrated from the Canary Islands to East Africa and Arabia through long distance dispersal.
Examination of subfamilial phylogeny in Bromeliaceae using comparative sequencing of the plastid locus ndhF.
TLDR
Parsimony analysis of 31 sequences of the chloroplast locus ndhF was used to address questions of subfamilial phylogeny in Bromeliaceae, and data suggest that Brocchinia (Pitcairnioideae) is the sister group to the remainder of Bromeli Families.
Shrinking the Violets: Phylogenetic Relationships of Infrageneric Groups in Viola (Violaceae) Based on Internal Transcribed Spacer DNA Sequences
TLDR
A phylogenetic study of the genus Viola used internal transcribed spacer (ITS) DNA sequences for 44 taxa representing many infrageneric groups in Viola plus outgroups Hybanthus concolor and Noisettia orchidiflora to find an Andean origin for the genus.
Tribal relationships in Onagraceae: implications from rbcL sequence data
TLDR
Cladistic analyses of sequence data from the chloroplast encoded rbcL gene produced results that bear on two malor issues: (i) intertribal relationships within Onagraceae, and (ii) congruence with other cladistic analyses.
Bromeliales, Related Monocots, and Resolution of Relationships among Bromeliaceae Subfamilies
TLDR
Cladistics, phenetics, and the understanding of chromosomal evolution were applied to questions of the relationships and resemblances among the three subfamilies of the monocot family Bromeliaceae, finding Velloziaceae of Bromeliflorae appear to be the most likely to share the same common ancestor with Bromeliacae.
