An updated classification for Apocynaceae
An updated suprageneric classification is provided for Apocynaceae to bring the family into better agreement with recent morphological and molecular, mainly phylogenetic-based, results. A total of…

The studies strongly suggest an African origin of the newly circumscribed Mussaenda, whereas Bremeria can be distinguished from the remaining Mussaendeae genera by having both reduplicates- and induplicate-valvate aestivation and densely pubescent styles.
ADVANCES IN APOCYNACEAE: THE ENLIGHTENMENT, AN INTRODUCTION1
The papers here present the most up-to-date overview of the Apocynaceae available at this time and include new results in phylogenetics, taxonomy, biogeography, pollination biology, and a pharmacophagous plant–butterfly interaction involving pyrrolizidine alkaloids.
Phylogenetics of the New World Subtribes of Asclepiadeae (Apocynaceae—Asclepiadoideae): Metastelmatinae, Oxypetalinae, and Gonolobinae
This study provides a framework for future study of the American MOG genera and highlights areas that need further attention and Chromosome numbers indicate a tendency for reduction in several clades.
Phylogeny and taxonomy of Tribulocarpus (Aizoaceae) : A paraphyletic species and an adaptive shift from zoochorous trample burrs to anemochorous nuts
The phylogenetic position and circumscription of the disjunct African genus Tribulocarpus is investigated with DNA sequences from plastid rps16 and trnLF, and nuclear ITS, and T. dimorphanthus is retrieved as paraphyletic with regard to T. retusus, endemic in Somalia.
Seed coat morphology of Aizoaceae–Sesuvioideae, Gisekiaceae and Molluginaceae and its systematic significance
Macro- and micromorphological characters of the seeds of 32 species belonging to Aizoaceae, Gisekiaceae and Molluginaceae were analysed for their taxonomic value, and seed characters support the independence of Gisekia in a family of its own.
Phylogeny of Sesuvioideae (Aizoaceae) - biogeography, leaf anatomy and the evolution of C4 photosynthesis
The well-resolved molecular phylogeny revealed an African/Arabian origin of the subfamily with Tribulocarpus as sister to a clade containing Trianthema, Sesuvium, Cypselea and Zaleya and might indicate multiple origins of the C4 pathway.
Leaf variegation in Caladium steudneriifolium (Araceae): a case of mimicry?
It was observed that the variegated leaf zones strongly resemble recent damages caused by mining larvae and therefore may mimic an attack by moth larvae and suggest that ovipositing moths are deterred by the miner-infestation mimicry.
DIVERSIFICATION OF ASCLEPIADOIDEAE (APOCYNACEAE) IN THE NEW WORLD1
Plastid sequences of trnL-F are used to estimate the age of biogeographical events in New World Asclepiadoideae and suggest that the subfamily arose somewhere in the Old World in the Late Eocene and that there were at least four independent episodes of dispersal to the New World.
Sabiceeae and Virectarieae (Rubiaceae, Ixoroideae): one or two tribes? New tribal and generic circumscriptions of Sabiceeae and biogeography of Sabicea s.l.
New tribal and generic limits of Sabiceeae (Rubiaceae) and biogeographical origin ofSabicea s.l. are revealed.
