Fossil history of the Menispermaceae (Ranunculales)
Annales de Paléontologie, 2009The Menispermaceae family (Ranunculales) includes more than 500 extant species. Climbers represent the majority of this family, and these plants are now distributed in all of the tropical and Subtropical regions of Americas, Asia and Africa. Their endocarps show a characteristic shape that is easily identified in the fossil floras.

The morphology and anatomy ofHydrastis (Ranunculales): Systematic reevaluation of the genus
The Botanical Magazine Tokyo, 1985Evidence from morphology and anatomy (including embryology), as well as from palynology, chemistry and cytology, indicates thatHydrastis is quite divergent from Ranunculaceae (in which the genus has been most often included) as well as from both Glaucidiaceae and Berberidaceae. Distinctive features ofHydrastis, which demarcate it from Ranunculaceae but

Floral development of Kingdonia (Ranunculaceae s. l., Ranunculales)
Plant Systematics and Evolution, 2004The flower of Kingdonia has a terminal position, thus the rhizome is sympodial. The floral organs initiate in spiral phyllotaxis. The androecium is centripetal in initiation but the sterile stamens are retarded in development compared with the fertile ones. The apex of the young carpel does not participate in the conduplication.

Phylogeny and Character Evolution of Papaveraceae s. l. (Ranunculales)
Systematic Botany, 2015Abstract— To explore the taxonomic status, phylogenetic patterns, and character evolution of various groups within Papaveraceae s. l. (Pteridophylloideae, Papaveroideae, Hypecoideae, and Fumarioideae), two data sets were created and analyzed using Bayesian inference, maximum likelihood, and parsimony methods: 1) a Ranunculales data set for 82 genera ...

TAXON, 2007
Menispermaceae (Moonseed family) are an important family within the basal eudicots. This study is a first attempt to infer phylogenetic relationships within Menispermaceae, focusing on morphological data and using cladistic methodology. Sampling included genera from all the eight tribes usually recognized within the family, and was representative of ...

Successive microsporogenesis in eudicots, with particular reference to Berberidaceae (Ranunculales)
Plant Systematics and Evolution, 2008The eudicot clade of angiosperms is characterised by simultaneous microsporogenesis and tricolpate pollen apertures. Successive microsporogenesis, where a distinct dyad stage occurs after the first meiotic division, is relatively rare in eudicots although it occurs in many early branching angiosperms including monocots.
