Biological Reviews, Volume 95, Issue 5, Page 1442-1466, October 2020., 2020 ABSTRACT Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above‐ and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of ...

Botanical Gazette, 1913 1. The pollen is normal. The haploid number of chromosomes is 12. 2. The third division in the embryo sac shows the diploid number of chromosomes to be 24. 3. Usually the ordinary 8-nucleate sac is organized, but occasionally antipodals organize in the micropylar end and the egg apparatus at the side of the sac, sometimes more than one egg organizing ...

PLANTS, PEOPLE, PLANET, Volume 1, Issue 4, Page 375-386, October 2019., 2019 Wild, perennial, herbaceous plant species have the capacity to provide both agricultural products and ecological services, such as soil stability and efficient absorption, over multiple years. Although perennial, herbaceous species are common in nature, these species were rarely domesticated.

Ecology and Evolution, Volume 9, Issue 17, Page 9977-9989, September 2019., 2019 In this article, we used a floristic dataset from a French citizen science project that records the plants growing in streets of the Île‐de‐France region. Urbanization had an effect on species occurrence through their reproductive traits, by selecting autogamous, self‐compatible, and nonentomophilous species, which strongly suggests a lower abundance ...

The classification of asexual organisms: Old myths, new facts, and a novel pluralistic approach
TAXON, Volume 67, Issue 6, Page 1066-1081, December 2018., 2018 Abstract Organisms reproducing via asexuality harbor a great diversity of lineages, morphotypes and ecotypes. However, classification of asexual taxa does not fit into contemporary species concepts, and hence the diversity of apomictic plant complexes is not well reflected in taxonomy.

Evidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013 This contribution presents information about the history of introduction, establishment, and local appropriation of Eurasian fruit trees—species and varieties of the genera Prunus and Citrus—from 15th century in two rural areas of Northern Argentina. By means of an ethnobotanical and ethnohistorical approach, our study was aimed at analysing how this ...

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum
Nordic Journal of Botany, Volume 2026, Issue 9, September 2026.There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

The Evolutionary Dynamics of Apomixis in Ferns: A Case Study from Polystichoid Ferns
Journal of Botany, Volume 2012, Issue 1, 2012., 2012 The disparate distribution of apomixis between the major plant lineages is arguably one of the most paradoxical phenomena in plant evolution. Ferns are particularly interesting for addressing this issue because apomixis is more frequent than in any other group of plants.
