Subtribe Scorzonerinae (Cichorieae, Asteraceae) contains 12 main lineages and approximately 300 species. Relationships within the subtribe, either at inter- or intrageneric levels, were largely unresolved in phylogenetic studies to date, due to the lack of phylogenetic signal provided by traditional Sanger sequencing markers. In this study, we empl...

Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense. We provide a re-evaluation of Scorzonera and other related genera, based on carpological (including anatomical)...

Premise: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq probe set and the outcomes of different phylogenetic analyses are investigated here. Methods: Hyb-Seq data from 112 Asteraceae samples were organized into groups at different ta...

The origin of Neotropical species diversity is strongly associated with the geological history of South America. Since the Miocene, a number of species radiations across different Neotropical lineages coincided with the rise of the Andes and the formation of the Isthmus of Panama. The species-rich genus Philodendron Schott (Araceae) is widely distr...

Abstract: The Lactuca lineage is one of nine lineages in the lettuce subtribe (Cichorieae, Asteraceae) distributed in Europe, Africa, Asia and North America. Within the Lactuca lineage two clades show disjunct Eurasian-North American distributions. One disjunct clade consists of diploids (x = 8) and allotetraploids (x = 17), the former restricted t...
Article
Comprising more than 25 000 species, the Sunflower Family (Compositae or Asteraceae) is the largest family of flowering plants. Many of its lineages have experienced recent and rapid radiations, and the family has a deep and widespread history of large-scale gene duplications and polyploidy. Many of the most important evolutionary questions about t...

Campanula s.l. is one of the most speciose flowering plant lineages of the Holarctic (ca. 600 species). In the present study we sequenced three regions of the plastid genome (petD, rpl16 and trnK/matK) across a broad sample of Campanula s.l., which markedly improved phylogenetic resolution and statistical support compared to previous studies. Based...

Abstract Background Oceanic archipelagos typically harbour extensive radiations of flowering plants and a high proportion of endemics, many of which are restricted to a single island (Single Island Endemics; SIEs). The Azores represents an anomaly as overall levels of endemism are low; there are few SIEs and few documented cases of intra-archipelag...

A new species, Pericallis menezesii, is described from the island of Porto Santo in the Madeiran archipelago. Morphological comparisons are made with its sister taxon, P. aurita which is now considered to be endemic to the island of Madeira.
Article
Full-text available
Premise of the study: Geographic isolation, habitat shifts, and hybridization have contributed to the diversification of oceanic island floras. We investigated the contribution of these processes to the diversification of Pericallis, a genus endemic to Macaronesia. Methods: Data from the chloroplast psaI-accD and trnV-ndhC regions and the nuclea...
Article
Full-text available
The almost cosmopolitan distribution of Samolus valerandi is unique in the genus Samolus L. (Samolaceae), which also includes 12–15 taxa with distributions restricted to smaller areas of the Southern Hemisphere. Recent molecular phylogenetic studies based on chloroplast and nuclear DNA sequences showed that the widespread S. valerandi and the North...

In a recent paper, two of us discussed diversity patterns and diversification processes in the Azores flora. Triantis et al. (2012, Journal of Biogeography, 39, 1179–1184) challenged our hypothesis that palaeoclimatic differences had an effect on diversification rates and suggested that area, island age and isolation explain diversity patterns. The...

Lettuce (Lactuca sativa L.) is the economically most important crop of the tribe Cichorieae of the sunflower family (Asteraceae), and Lactuca one of its widest known genera. Lactuca is also the name giving member of one of the larger groups of the tribe, the Lactuca alliance, which is treated today as the subtribe Lactucinae. It comprises more than 200 species with a preference of montane habitats, distributed in Europe, Africa, Asia and North America. The subtribe has two centres of current diversity, one in the SE European-SW Asian region, the other in China and the adjacent Himalayan region. The classification of no other alliance of the tribe has faced so many controversies over the last 200 years than that of Lactuca and its presumed allies. We illuminate the evolution of the diversity of this lineage with studies on its phylogeny, biogeography and taxonomy. The results lead to a revised generic classification of the Lactuca alliance and to monographic systematic treatments of its genera.
