Taxonomic novelties in the Asteraceae–Inuleae with the description of a new genus, Galgera separate from Laggera Open
Phylogenetic analyses of DNA sequences from the plastid gene ndhF from a large number of species of the Asteraceae tribe Inuleae reveal the need for some taxonomic and nomenclatural changes. The genera Laggera, Pentanema and Pluchea as pre…

The Malagasy enigmatic genus Apodocephala (Asteraceae), a new member of the tribe Athroismeae Open
Apodocephala is a small genus of nine species of shrubs and trees endemic to Madagascar and currently classified in the tribe Astereae (Asteraceae). However, its present tribal position has been questioned, as it lacks some of the salient …

Phylogeny of <i>Anisopappus</i> with species circumscriptions revisited (Asteraceae: Athroismeae) Open
Anisopappus (Asteraceae: Athroismeae) is a genus with its main distribution in Africa (one species also in Asia), currently considered to include around 21 species. A molecular phylogenetic study of Anisopappus is presented for the first t…

The genus Duhaldea in India Open
Based on the field and herbarium data, six species of the genus Duhaldea (sensu stricto) are recognized in India. A key to the Indian species, brief descriptions and illustrations are provided alon ...

Architectural traits constrain the evolution of unisexual flowers and sexual segregation within inflorescences: an interspecific approach Open
Male and female unisexual flowers have repeatedly evolved from the ancestral bisexual flowers in different lineages of flowering plants. This sex specialization in different flowers often occurs within inflorescences. We hypothesize that i…

Species diversification in the Mediterranean genus Chiliadenus (Inuleae-Asteraceae) Open
Chiliadenus is a small genus in the Inuleae (Asteraceae), consisting of ten species with allopatric distributions along the southern edge of the Mediterranean Sea. The different species have restricted areas of distribution, with only one …

What explains high plant richness in East Asia? Time and diversification in the tribe Lysimachieae (Primulaceae) Open
Summary What causes the disparity in biodiversity among regions is a fundamental question in biogeography, ecology, and evolutionary biology. Evolutionary and biogeographic processes (speciation, extinction, dispersal) directly determine s…

Phylogeny of the <i>Inula</i> group (Asteraceae: Inuleae): Evidence from nuclear and plastid genomes and a recircumscription of <i>Pentanema</i> Open
The Inula complex (Asteraceae: Inulinae) is a monophyletic group which comprises eight genera distributed in Eurasia and Africa: Amblyocarpum, Carpesium, Chrysophthalmum, Inula, Pentanema, Rhanteriopsis, Telekia , and Varthemia. With the a…
