This special issue contains 11 articles headed by a tribute to Edith L. Taylor, discussing topics regarding paleobotany, such as a new genus and new species of a Late Devonian Lycopsid, periderm production and periderm occurence in Paleozoic plants, conifer diversity in Middle Triassic, pollen...

Participatory plant breeding (PPB) is the process by which the producers and other stakeholders are actively involved in a plant-breeding programme, with opportunities to make decisions throughout. The Working Group on Participatory Plant Breeding was established in 1996 under the framework of the...

The tribe Crescentieae includes Amphitecna (21 species), Crescentia (six species), and Parmentiera (10 species), three genera of understory trees with a center of diversity in Central America and a small number of species in the Antilles and northern South America. Species in Crescentieae are...

Holocene vegetation changes are good indicators of climate change/and or human impacts. The environmental history in the semi-arid region with Caatinga vegetation in Northeast Brazil has been still little studied. A 420 cm-long sediment core collected in a mire at the Catimbau National Park, State...

This paper reports on the genus Cobbionema Filipjev, 1922 in Sweden with the description of four species and a revision of the genus. Cobbionema acrocerca Filipjev, 1922 is relatively small in size, with a tail that has a conical proximal and a digitate distal section. Cobbionema cylindrolaimoides...

High-throughput (next-generation) DNA sequencing has removed barriers to data quantity and quality, and it has produced phylogenies with high statistical support. Such data are useful to address phylogenetic congruence among individual genes. Concatenated analyses of unlinked genes often produce...

Cinnamomum zeylanicum Blume, known as Ceylon cinnamon, is native to Sri Lanka, whereas Cinnamomum cassia J. Presl (Cassia cinnamon) and other types of Cinnamomum spp. are grown in China and many other parts of Asia. Ceylon cinnamon is relatively expensive due to its chemical composition, high...

The lower reaches of the Yangtze River have a long history of human occupation and rice cultivation, but our understanding of human activities in the mountainous region south of the lower Yangtze is still limited. In this study, we present a high-resolution vegetation record spanning the past 2900...

The new isoflavonoid kirkinone A (1) and biflavonoid kirkinone B (2) along with six known compounds (3-8) were isolated from the methanolic extract of the root bark of Ochna kirkii. The compounds were identified by NMR spectroscopic and mass spectrometric analyses. Out of the eight isolated natural ...

Palaeoecological studies in coversand areas are sparse as organic remains generally do not preserve well in sandy deposits. An AMS-dated Holocene peat sequence in a palaeochannel in a natural depression (the Liereman), flanked by coversand ridges proved to be an exceptional and valuable archive of...
