Premise of the study: Observations of floral ontogeny indicated that floral organ initiation in pentapetalous flowers most commonly results in a median-abaxial (MAB) petal during early development, a median-adaxial (MAD) petal being less common.

In Solanaceae, a group dominated by actinomorphic-flowered species, floral zygomorphy is frequently observed among the early-branching clades. Morphological studies indicated that a zygomorphic androecium is much more common than a zygomorphic corolla in the family. Ontogenic studies suggested the evolution of floral zygomorphy in these two whorls...

Observations of floral ontogeny indicated that floral organ initiation in pentapetalous flowers most commonly results in a medially positioned abaxial (MAB) petal instead of a medially positioned adaxial (MAD) petal during early development. It was proposed that the conservation of patterns of floral organ initiation might impose developmental cons...

Two species characterized by locellate anthers are treated, belonging to different sections of Clusia. One of these species, Clusia favus, is described as new. A new name for a species with an unusual volcano-shaped male androecium, belonging to Clusia section Phloianthera, but originally described within the genus Arrudea, is also proposed. A very...
Article
Clusia shows high infrageneric and sometimes infraspecific diversity in growth form, floral morphology and pollination biology. Species offering floral resin as a reward to pollinating bees often show unique androecial structures. We investigate the stamen structure of two groups of Clusia with resin flowers and anthers with numerous locelli: all t...

Mutualistic symbioses with mycorrhizal fungi are widespread in plants. The majority of plant species associate with arbuscular mycorrhizal (AM) fungi. By contrast, the minority associate with ectomycorrhizal (EM) fungi, have abandoned the symbiosis and are nonmycorrhizal (NM), or engage in an intermediate, weakly AM symbiosis (AMNM). To understand...

Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which new phenotypes evolve, the differences in speciation and extinction rates across lineages, and whe...

An update of the Angiosperm Phylogeny Group (APG) classification of the orders and families of angiosperms is presented. Several new orders are recognized: Boraginales, Dilleniales, Icacinales, Metteniusiales and Vahliales. This brings the total number of orders and families recognized in the APG system to 64 and 416, respectively. We propose two a...

1.The question posed by the title of this paper is a basic one, and it is surprising that the answer is not known. Recently assembled trait datasets provide an opportunity to address this, but scaling these datasets to the global scale is challenging because of sampling bias. Although we currently know the growth form of tens of thousands of specie...

Early flowering plants are thought to have been woody species restricted to warm habitats. This lineage has since radiated into almost every climate, with manifold growth forms. As angiosperms spread and climate changed, they evolved mechanisms to cope with episodic freezing. To explore the evolution of traits underpinning the ability to persist in...

1. Plant traits vary widely across species and underpin differences in ecological strategy.

Premise of research. The clusioid clade is a member of the large rosid order Malpighiales and contains ∼1900 species in five families: Bonnetiaceae, Calophyllaceae, Clusiaceae sensu stricto (s.s.), Hypericaceae, and Podostemaceae. Despite recent efforts to clarify their phylogenetic relationships using molecular data, no such data are available for...

The angiosperm order Malpighiales includes ∼16,000 species and constitutes up to 40% of the understory tree diversity in tropical rain forests. Despite remarkable progress in angiosperm systematics during the last 20 y, relationships within Malpighiales remain poorly resolved, possibly owing to its rapid rise during the mid-Cretaceous. Using phylog...

Using the French botanist Henri Cassini's work as an example, the complex relationship between characters, groups and relationships in the period 1770-1850 is explored.
