Molecular Phylogenetics and Patterns of Floral Evolution in the Ericales
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.

Crypteroniaceae are the first plant group for which the out-of-India hypothesis is well corroborated by molecular-based estimates of divergence times and are also the first to be identified as a sister to a clade formed by three small African taxa.
Plant Tissues in 3D via X-Ray Tomography: Simple Contrasting Methods Allow High Resolution Imaging
This work represents a crucial improvement of previous methods, allowing new directions of research to be undertaken in areas ranging from morphology to systems biology.
Phylogeny, historical biogeography, and diversification of angiosperm order Ericales suggest ancient Neotropical and East Asian connections.
Normapolles plants: a prominent component of the Cretaceous rosid diversification
A new genus, Dahlgrenianthus, is described from the Late Cretaceous of southern Sweden and thought to be related to various members of the core Fagales, but the group is obviously not monophyletic.
Cunoniaceae in the Cretaceous of Europe: Evidence from Fossil Flowers
A new genus and species is formally described, Platydiscus peltatus gen. et sp.

Model-based reconstructions for ancestral flowers at the deepest nodes in the phylogeny of angiosperms, using the largest data set of floral traits ever assembled, allow us to propose a new plausible scenario for the early diversification of flowers, leading to new testable hypotheses for future research on angiosperm research.
Molecular phylogeny and floral evolution of Penaeaceae, Oliniaceae, Rhynchocalycaceae, and Alzateaceae (Myrtales).
The resulting phylogenies suggest that the monospecific New World Alzateaceae is sister to the three African taxa and that the MONOSpecific Rhynchocalycaceae is Sister to Oliniaceae/Penaeaceae, while flowers of both families are most parsimoniously interpreted as having an obhaplostemonous organization.

New Normapolles reproductive structures are described from two Late Cretaceous localities, Mira and Esgueira (Olho de Agua), in the Beira Litoral region of western Portugal. They are assigned to a…
Structure and Development of the Flowers in Mendoncia, Pseudocalyx, and Thunbergia (Acanthaceae) and Their Systematic Implications
Floral structure and development of Mendoncia, Pseudocalyx, and Thunbergia strongly suggest that these genera form a natural group.
