Embryology of the Irvingiaceae, a family with uncertain relationships among the Malpighiales
Journal of Plant Research, 2010The Irvingiaceae, one of 40 families of the Malpighiales, comprise a small woody family of 10 species in three genera distributed in Old World tropics. Its relationships with other families are unclear, although recent molecular analyses suggest affinities with Linaceae, Caryocaraceae, Erythroxylaceae, and Rhizophoraceae.

Floral structure and palynology of Podostemum weddellianum (Podostemaceae: Malpighiales)
Plant Systematics and Evolution, 2010The family Podostemaceae is exceptional among angiosperms because of its uncommon biology and morphology, the absence of double fertilisation and endosperm, and the obscure distinction between root, stem, and leaf. The highly modified morphology produced by reductions and specialisations is reflected in the multiple positions that the Podostemaceae has

Pollen Evolution in the Clusioid Clade (Malpighiales)
International Journal of Plant Sciences, 2012The clusioid clade is one of the major subclades identified within the large, diverse rosid order Malpighiales, using molecular data. However, nonmolecular synapomorphies are unclear, and more comparative data are needed to elucidate deep relationships within the order.

Protection and attraction: bracts and secretory structures in reduced inflorescences of Malpighiales
Flora - Morphology, Distribution, Functional Ecology of Plants, 2016Abstract Flower protection and attraction of pollinators are mainly associated with the secretory structures. The flower-pollinator relationship corroborates these functions and is an essential link in the interpretation of different floral morphologies, such as the pseudanthia occurring in Euphorbiaceae and Peraceae, two near families in ...

Evolution of Pollen and Tapetal Characters in Ochnaceae (Malpighiales)
International Journal of Plant Sciences, 2013Ochnaceae are members of the recently recircumscribed and extremely diverse rosid order Malpighiales. They consist of three lineages, Ochnoideae, Quiinoideae, and Medusagyne oppositifolia (jellyfish tree), a critically endangered endemic from the Seychelles. However, relationships among these lineages are unclear, as are relationships between Ochnaceae

Caryocaraceae Voigt (Malpighiales): a Synthesis Based on Science Mapping and Systematic Review
The Botanical Review, 2020Caryocaraceae, a family of plants widely distributed throughout the Neotropic region, includes two woody genera: Anthodiscus and Caryocar - with 26 species. The family includes species with medical, timber, food, ecological, and cultural importance. Here we aim to unveil the current state of scientific knowledge of Caryocaraceae through a systematic ...

Taxonomical update of the genus Drypetes (Malpighiales: Putranjivaceae) in Cuba
PhytotaxaDrypetes is a pantropical genus of 220 species of dioecious trees and shrubs, where around 20 of them are found in the Americas, with a hotspot in the West Indies. In Cuba, the number of taxa and its identities have changed throughout the years and the infraspecific classification has never being taken into consideration.

The eudicot order Malpighiales contains ∼16000 species and is the most poorly resolved large rosid clade. To clarify phylogenetic relationships in the order, we used maximum likelihood, Bayesian, and parsimony analyses of DNA sequence data from 13 gene regions, totaling 15604 bp, and representing all three genomic compartments (i.e., plastid: atpB ...

Plant Systematics and Evolution, 2010
New observations are presented on the ontogeny, vasculature and morphology of both staminate and pistillate flowers of Croton and Astraea. These data support earlier hypotheses that the filamentous structures in pistillate flowers represent reduced and transformed petals.
